following calendar month. All progress payments shall be made to Seller
upon submission of invoices by Seller in accordance with Section 3.5,
provided that each invoice submitted by Seller pursuant to the
applicable Appendix shall include charges only for those applicable
events or durations as described in Appendix B. All payments to be made
under this Section 3.3 shall be in accordance with Sections 3.1 and 3.4
of this Contract.
3.4 CHANGES IN TOTAL CONTRACT PRICE. In the event that a change in the
Contract scope pursuant to Section 9.1 results in a change in the Unit
Contract Price for one or more Units and in the Total Contract Price,
all payments shall be adjusted accordingly. However, if the change

CONFIDENTIAL
to the extent of the next payment and each subsequent payment as it
becomes due.
3.5 PROGRESS PAYMENT INVOICES. Invoices shall be received by Buyer not
later than the fifteenth (15th) calendar day of the month preceding the
month in which payment is due, and such invoices shall be due and
payable on the twenty-fifth (25th) calendar day of the month following
the month in which such invoice is received by Buyer, except that the
Shipment Payments (as described in Appendix B) and the Final Payments
(as described in Appendix B), shall each be due within three (3)
Business Days respectively after receipt of proper invoices documenting
the events or dates shown in Appendix B. In the event payment is not
received by the due date, interest shall accrue on such amount at an
annual rate of interest equal to the prime rate of The Chase Manhattan
Bank, N.A. in effect on the due date plus one percent (1%). Buyer may
withhold payment of the disputed portion of any invoice until such
dispute is resolved to the reasonable satisfaction of Buyer. If it is
determined that Buyer was justified in withholding payment or if the
dispute is settled in favor of Buyer, Buyer shall not pay interest on
the amounts withheld. If it is determined that Buyer was not justified
in withholding such amounts or if the dispute is settled in favor of
Seller, Buyer shall pay interest at the rate provided above, from the
time the withheld amount was due. Buyer may retain the Final Payment
for each Unit in Phase I in the amount of five percent (5%) per Unit
("Retainage") as security for any liquidated damages which may become
due under this Contract until Substantial Completion is achieved for
all Units in Phase I or until payment is made of Unit Performance
Liquidated Damages with respect to all of the Units in Phase I;
provided that if an election is made by Seller pursuant to Section
17.2(d) with respect to one or more Units in Phase I, then the
Potential Liquidated Damages calculated as set forth in Section 17.2(d)
shall be aggregated for all Units in Phase I and to the extent that the
aggregate Potential Liquidated Damages for such Units is less than the
Retainage for all of the Units in Phase I, Buyer shall pay to Seller
the amount by which the Retainage exceeds such aggregate Potential
Liquidated Damages; provided that as a condition to such payment each
Unit in Phase I which is not subject to an election under Section
17.2(d) shall have achieved Substantial Completion. Buyer may retain
the Final Payment for each Unit in Phase II in the amount of five
percent (5%) per Unit ("Retainage") as security for any liquidated
damages which may become due under this Contract until (i) the Deferred
Tests are completed for Units #2 and #3 and (ii) Substantial Completion
is achieved for all Units or until payment is made of final liquidated
damages with respect to all of the Units; provided that if an election
is made by Seller pursuant to Section 17.2(d) with respect to one or
more Units in Phase II, then the Potential Liquidated Damages
calculated as set forth in Section 17.2(d) shall be aggregated for all
Units in Phase II and to the extent that the aggregate Potential
Liquidated Damages for such Units is less than the Retainage for all of
the Units in Phase II, Buyer shall pay to Seller the amount by which
the Retainage exceeds such aggregate Potential Liquidated Damages;
provided that as a condition to such payment each Unit in Phase II
which is not subject to an election under Section 17.2(d) shall have
achieved Substantial Completion. Notwithstanding the achievement of
Substantial Completion for a Unit, Buyer may continue to hold a portion
of the Retainage for such Unit equal to Twenty Five Thousand Dollars
($25,000) until the satisfactory completion of tests with respect to
the
9
CONFIDENTIAL
Combustion Turbine Evaporative Cooler for such Unit plus an amount
equal to twice the value of any Punch List items for such Unit. Buyer
and Seller shall mutually agree upon an estimated cost for each item
included by Buyer on the Punch List, and Buyer shall, on a monthly
basis, release such amounts from such Retainage as correspond to twice
the value of those items on the Punch List which Seller has completed
and when all remaining Punch List items are complete and approved by
Buyer, Buyer shall release the entire Retainage. In the event that,
following timely Delivery of all of the Units in a Phase in accordance
with the provisions of this Contract, all of the Units in a Phase have
not achieved Substantial Completion by the date ("Delayed Final Payment
Date") which is the earlier of (i) six (6) months after the Scheduled
Date of Commercial Operation for such Phase, as such date is determined
at the time of execution of the EPC Agreement or (ii) June 1, 2002 for
Phase I and June 1, 2003 for Phase II, as applicable, through no cause
of Seller (including any claim of Excusable Delay by Seller under this
Contract), then Buyer shall pay to Seller all of the Retainage for the
Units in such Phase (if, with respect to Phase II only, less than [*]
of Technical Services have been used at such time with respect to all
of the Units, Buyer shall receive a credit against any Retainage to be
paid equal to the difference between [*] and the number of man-weeks
actually used multiplied by [*]) within three (3) Business Days after
the Delayed Final Payment Date for such Phase, provided that payment of
such Retainage shall not release Seller from any liability or
obligation due or which may become due under this Contract, except
that Seller will no longer be obligated to provide additional Technical
Services as set forth in Section 19.1. Payment of Retainage to Seller

or other failures to perform the terms of this Contract caused by
events beyond its reasonable control which Seller is unable to
overcome by the exercise of reasonable diligence, including acts
of God, acts (or failure to act) of Buyer, acts of civil or
military authority, governmental priorities, fires, floods,
epidemics, strike or labor disturbance, war, or riot, (collectively,
"Excusable Delay"); provided, however, that such Excusable Delay must
directly, adversely, and materially affect a specific portion of the
manufacture of a Unit or Units or Seller's obligations under this
Contract with respect to such Unit or Units and Seller shall establish
that such Excusable Delay will cause a delay in Delivery as set forth
in Article 4 or a required performance date in this Contract. In the
event of an Excusable Delay, the Party claiming Excusable Delay will
use commercially reasonable efforts to mitigate the effects of the
Excusable Delay on its performance of the Contract, including, if
applicable, Seller making available replacement Equipment at the
earliest possible date. In the event of any such Excusable Delay
with respect to any Unit, the Scheduled Delivery Date, and any
performance requirement or other date of required performance,
shall be extended only by that amount of delay demonstrated by
Seller to have been caused by such Excusable Delay, Seller shall
give Buyer written notice of the occurrence of any such event
within seven (7) days after Seller becomes aware or reasonably
should have become aware of an Excusable Delay which notice shall
include a good faith estimate of the expected impact that such
event will have on Delivery or the performance of Seller under
this Contract.

adjustment to the Total Contract Price and any applicable Unit Contract
Prices and time of delivery and any other pertinent provisions of the
Contract. Any such change in the Equipment, Documentation and/or
Services and in the Total Contract Price and any Unit Contract Price or
the Scheduled Delivery Date or any other pertinent provisions of the
Contract, shall be indicated on the change order. If Buyer and Seller
do not agree upon the price of such change or its effect on the
Scheduled Delivery Date or its effect on any other pertinent provisions
of the Contract, Buyer may issue a Directed Change Order, so long as
such Directed Change Order is reasonably capable of being performed by
Seller and is intended solely to cause the Documentation, Equipment or
Services to comply with Applicable Laws, and Seller shall proceed
without undue delay to perform the change described in the Directed
Change Order, as set out in such order and consistent with this Section
9.1. Within ten (10) days after Buyer's submission of a Directed Change
Order, Seller shall submit a Dispute Notice to Buyer setting out the
reasons for Seller's disagreement with the price of such change or its
effect on the Scheduled Delivery Date or its effect on any other
pertinent provisions of Seller, and the Parties shall resolve such

CONFIDENTIAL
ARTICLE 10. WARRANTY
10.1 WARRANTIES AND REPRESENTATIONS.
(a) Seller warrants and represents to Buyer that the Equipment to
be delivered hereunder shall be as described in the
Specifications; shall be designed and fit for the purpose of
generating electric power in accordance with the
Specifications; shall be new; and shall be free from defects
in material, workmanship, and title; and that the Services
shall be performed in a competent, diligent, workmanlike
manner in accordance with generally accepted industry
standards. Seller further warrants and represents to Buyer
that the Documentation, Specifications, and other materials
which are to be provided to Buyer under this Contract, will
faithfully and accurately reflect the Equipment provided under
this Contract.
(b) Seller warrants and represents to Buyer that Seller will have
good and indefeasible title, and will at the time of transfer
of title under this Contract, convey to Buyer good and
indefeasible title to the Equipment, free and clear of any and
all liens and security interests which may arise by or through
Seller or any subcontractor of Seller.
10.2 WARRANTY PERIOD. The warranties set forth in Section 10.1(a) for each
Unit shall apply to defects which appear prior to Substantial
Completion and during a period of either (i) twelve (12) Months
following the earlier of (1) the date on which Seller makes a valid
election with respect to such Unit under Section 17.2(d) or (2) the
date such Unit achieves Substantial Completion; or (ii) thirty (30)
Months from the actual date of Delivery of such Unit to Buyer,
whichever period expires first ("Warranty Period"). Where any item of
Equipment is used with more than one Unit, the warranty on such item
shall be for the same period as the warranty on the Unit with which it
is first used. The Warranty Period for a Unit shall be extended on a
day-for-day basis for any period of time in excess of ten (10) days
that the Unit is not capable of operating due solely to a warranty
claim attributable to Seller. For the purposes of this paragraph, the
number of days of Warranty Period extension shall be counted as those
days in excess of ten (10) between:
(i) the date the Unit is removed from service, or unable to return
to service, solely due to a warranty nonconformity for which Seller is
responsible; and
(ii) the date the corrective work is complete and Seller advises that
the Unit is available for return to service.
"Substantial Completion" of a Unit shall mean the satisfaction by such
Unit of each of the Liquidated Damage Performance Guarantees,
Performance Guarantees, Demonstration Test Requirements and the
Availability Test Requirements under Article 16; provided that with
respect to Units #2 and #3, certain tests as indicated in Section 3.15
of Exhibit C
21
CONFIDENTIAL
("Deferred Tests") shall be deferred and the performance requirements
of such Deferred Tests shall not be a condition of Substantial
Completion of such Units. The Warranty Period for the warranties set
forth in Section 10.1(b) shall extend for a period of five (5) years
from the date of this Contract.
10.3 GENERAL CONDITIONS OF WARRANTY. The warranties and remedies set forth
herein are conditioned upon the following:
(a) The proper receipt, handling, storage, installation, use,
inspection, operation and maintenance of the Equipment by
Buyer in accordance with the Specifications and written
service manuals and written advisories (to the extent such
service manuals and advisories are not inconsistent with the
terms of this Contract including the Specifications) provided
by Seller pursuant to the Contract, and, in the absence
thereof, Buyer following generally accepted industry practices
in regard to the above activities.
(b) The Equipment not being subjected to accident, alteration,
abuse or misuse by Buyer, which directly causes a defect in
the Equipment.
(c) Buyer shall allow Seller the reasonable opportunity to review
operating and maintenance records relating to the Facility at
which the warranted Equipment is located and shall provide
Seller's representatives reasonable access to the Site for the
purpose of observing the Equipment and the operation and
maintenance thereof.
10.4 WARRANTY OBLIGATIONS.
(a) Except with respect to the warranties set forth in Section
10.1(b), if during the applicable Warranty Period, the
Equipment or Documentation delivered and/or Services
performed under this Contract do not meet the above
warranties, then Buyer shall promptly notify Seller, not later
than thirty (30) days after the expiration of the Warranty
Period, and make the Equipment or Documentation available
promptly for correction; provided that Buyer may elect to
defer the correction for a reasonable period of time to permit
Buyer's continued use of the Equipment, but Buyer assumes the
risk of any additional damage which may arise from the
deferral of such correction. Seller, at its expense, shall
thereupon correct any defect, at its option, by (i)
re-performing the defective Service, (ii) modifying or
repairing any Equipment or Documentation not in compliance
with Section 8.1, and/or (iii) repairing, replacing, or
modifying any defective Equipment, or any defects in the
Documentation (including repairing, replacing, or modifying
any parts of the Equipment damaged ("Collateral Damage") as a
result of the defective Service, defective parts, or defective
Documentation, except that Seller shall be entitled to be
reimbursed by Buyer for the costs incurred by Seller with
respect to repairing the Collateral Damage, but only to the
extent of any insurance proceeds
22
CONFIDENTIAL
received by Buyer to cover the expense of repairing such
Collateral Damage); provided that in repairing, replacing,
or modifying any Equipment, Buyer shall not materially
change the functionality or performance of the Equipment to
the detriment of Buyer. Seller shall provide technical
advisory services reasonably necessary for any such repair
or replacement. If required to avoid or mitigate a forced
outage, warranty work and services by Seller shall be
performed on a twenty-four (24) hours a day, seven (7) days
a week basis. Such warranty work and services are limited to
the Equipment supplied and do not include removal and
replacement of structures or other parts of the facility
reasonably necessary to conduct the warranty work. In the
event Seller shall fail to undertake and perform its
warranty obligations within a reasonable time, Buyer may,
with prior written notice to Seller, perform or retain a
third party contractor to perform such warranty work and
Seller shall be liable for the reasonable costs thereof. In
such event, Seller's ongoing warranty obligations on the
portion of work on which Buyer or a third party contractor
are performing such warranty work shall only continue if
Seller gives written approval, which shall not be
unreasonably withheld, to the remedial work performed by
Buyer or third party contractor.
(b) Seller shall perform its warranty obligations under this
Contract without materially changing the performance
of the Equipment to the detriment of Buyer. In the
event that following the performance of warranty
obligations by Seller, Buyer believes that the
performance of the Equipment with respect to Net
Equipment Electrical Output or Net Equipment Heat
Rate may have materially changed to the detriment of
Buyer because of the work done under the warranty
obligation. Buyer shall conduct retests of the
Equipment to determine any such changes in Net
Equipment Electrical Output or Net Equipment Heat
Rate (adjusted in accordance with the degradation
curves attached in Appendix C). Seller shall be
notified of such tests and shall be permitted to
witnesses such tests. If the tests performed by
Buyer indicated that the Net Equipment Electrical
Output or Net Equipment Heat Rate of the Equipment
has materially changed to the detriment of Buyer
(after adjusting for degradation in accordance with
the degradation curves attached in Appendix C),
Seller may attempt to remedy and retest the
Equipment (all retesting to be conducted by Buyer
under Seller's technical guidance) for a period not
to exceed 60 days, provided that Seller's remedy and
testing will not unreasonably interfere with the
normal and continuous operation of the Equipment
and that all changes, adjustments and retesting
shall be at Seller's expense, excluding fuel and
operating expenses. In the event that at the end of
such period, despite the best efforts of Seller to
remedy the defect in a manner which does not
materially change the Net Equipment Electric Output
or Net Equipment Heat Rate of the Equipment to the
detriment of Buyer, the Net Equipment Electrical
Output or Net Equipment Heat Rate of the Equipment,
as measured by the final test performed, has
materially changed to the detriment of Buyer because
of the work done under the warranty obligation.
Seller shall pay to Buyer liquidated damages as a
predetermined reasonable and exclusive remedy for
such reduced performance and not as a penalty for
any such change, based upon the following items:
23
CONFIDENTIAL
(i) NET EQUIPMENT ELECTRICAL OUTPUT - [*] for each
kilowatt that the Net Equipment Electrical Output
(using an aggregated number for all reworked Units
based upon the testing of all reworked Unit(s) at
the Project) measured after such warranty work is
less than the Final Test Value for Net Equipment
Electrical Output of such Unit(s) measured during
Acceptance Testing, adjusted in accordance with
the degradation curve attached in Appendix C.
(ii) NET EQUIPMENT HEAT RATE - [*] for each BTU per
kilowatt hour per Unit that the Net Equipment Heat
Rate (determined as an average for all reworked
Unit(s) based upon the testing of all reworked
Unit(s) at the Project) measured after such
warranty work and when operated on natural gas is
greater than the Final Test Value for Net
Equipment Heat Rate (determined as an average for
all Unit(s)) measured during Acceptance Testing
when operated on natural gas, adjusted in
accordance with the degradation curve attached in
Appendix C, plus [*] for each BTU per kilowatt
hour per Unit that the Net Equipment Heat Rate
(determined as an average for all reworked
Unit(s) based upon the testing of all reworked
Unit (s) at the Project) measured after such
warranty work and when operated on fuel oil is
greater than the Final Test Value for Net
Equipment Heat Rate (determined as an average for
all Unit(s)) measured during Acceptance Testing
when operated on fuel oil, adjusted in accordance
with the degradation curve attached in Appendix C.
Seller's total aggregate liability for liquidated damages
under this Section 10.4 shall not exceed [*] of the
Contract Price. Payment of liquidated damages under
this Section 10.4 shall relieve Seller from all further
liability with respect to the change in Net Equipment
Electrical Output or Net Equipment Heat Rate of the Equipment
but shall not relieve Seller in any way from any warranty
obligations under this Contract.
10.5 EXTENSION OF WARRANTY PERIOD. Any modified, repaired or replaced part
of the Equipment, revised Documentation and/or service furnished in
connection therewith and any Service re-performed under the aforesaid
warranty shall carry warranties on the same terms as set forth above
except that the warranty period shall be for a period of one (1) year
from the date of such modification, repair or replacement, revision, or
reperformance. Seller's warranty obligations with respect to any Unit,
if not terminated earlier pursuant to this Article 10, shall terminate
on and shall be subject to the overall warranty limit of, the lesser of
four (4) years after Substantial Completion of the Unit, or five (5)
years after Delivery of the Unit.

ARTICLE 17. LIQUIDATED DAMAGES AND ACCEPTANCE TESTING
17.1 SCHEDULE LIQUIDATED DAMAGES. In the event of a delay in Shipment or
Delivery (as applicable, depending upon which of such events has an
applicable Guaranteed Date in Section 4.1(a)) of a Unit or if Seller's
failure to comply with the requirements of this Contract with respect
to Equipment and Services causes a delay in the achievement of
Commercial Operation of one or more Units, the Parties agree that
Buyer's loss would be difficult to determine. Each Party acknowledges
and agrees, after taking into account the terms of this Contract and
all relevant circumstances at the date hereof, that the liquidated
damages payable under this Section 17.1 represent a reasonable and
genuine pre-estimate of the damages which would be suffered by Buyer in
the event of a delay in the Delivery or Shipment (as applicable) of one
or more Units or a delay in the achievement of Commercial Operation of
one or more Units and does not constitute a penalty. Accordingly,
Seller and Buyer agree, as a predetermined reasonable and exclusive
remedy for any such loss to the following liquidated damages:
(a) SHIPMENT OR DELIVERY.
Except for Spare Parts, in the event that Shipment or Delivery
(as applicable depending upon the Guaranteed Date) of a Unit
(as defined in Section 4.1(d)) is not made on or before the
applicable Guaranteed Date for such Unit as set forth in
Section 4.1(a) due to causes not excused by the provisions of
this Contract, daily liquidated damages shall accrue (subject
to the notice requirements of Section 4.1(d)(i) and (ii) in
the event that certain Equipment is missing) at the following
rates for each full day that Shipment or Delivery (as
applicable) of such Unit occurs after the Guaranteed Date:
for days one (1) through fourteen (14), the sum of
Twenty Thousand Dollars ($20,000) per day, per
Unit; and for days beyond the fourteenth (14th) day,
the sum of Forty Thousand Dollars ($40,000) per day,
per Unit.
(b) COMMERCIAL OPERATION. To the extent that Seller's failure to
comply with the requirements of this Contract with respect to
a Unit is the primary cause of one or more days that the Unit
does not achieve Commercial Operation by the Scheduled Date of
Commercial Operation for such Unit and such cause of delay is
not excused by the provisions of this Contract, Seller agrees
to pay liquidated damages in accordance with the following
schedule: for days one (1) through fourteen (14), the sum of
Thirty Thousand Dollars ($30,000) per day, per Unit; and for
days beyond the fourteenth (14th) day, the sum of Fifty
Thousand Dollars ($50,000) per day, per Unit.
(i) If, despite the efforts of the EPC Contractor to
mitigate the effects of late Shipment or Delivery
under Section 17.1(a), such late Shipment or
37
CONFIDENTIAL
Delivery of a Unit is the primary cause of a delay of
any day the Unit does not achieve Commercial Operation
by the Scheduled Date of Commercial Operation for such
Unit (excluding the first thirty (30) days of late
Shipment or Delivery under Section 17.1(a) which shall
be deemed to have no effect on the achievement of
Commercial Operation), Seller shall pay liquidated
damages to Buyer in accordance with the schedule set
forth in Section 17.1(b) above, provided that in
determining the amount of any liquidated damages under
this Section 17.1(b)(i) for delay after the first
thirty (30) days, the liquidated damages paid by
Seller under Section 17.1(a) with respect to each day
of delay shall reduce the amount of liquidated damages
due under this Section 17.1(b)(1) for such
corresponding day of delay. FOR EXAMPLE, if Commercial
Operation of a Unit is fifty (50) days late, all of
which was caused by late delivery of such Unit, the
first thirty (30) days of late Commercial
Operation are disregarded. Liquidated damages under
this Section 17.1(b)(1) will be $10,000 per day for
each day thereafter through the fiftieth day,
calculated by using $50,000 for the thirty first day
of delay in achieving Commercial Operation as shown in
the schedule at the beginning of this Section 17.1(b)
minus $40,000 of liquidated damages paid for such gas
turbine Unit which was delivered thirty-one days late,
and continuing similarly with such calculation for
each of the days through the fiftieth day.
(ii) If, excluding any and all effects of any late
Shipment or Delivery under Section 17.1(a), the
actions or inactions of Seller are the primary cause
of a delay of any day a Unit does not achieve
Commercial Operation by the Scheduled Date of
Commercial Operation for such Unit and such cause of
delay is not excused by the provisions of this
Contract, Seller shall pay liquidated damages to Buyer
in accordance with the schedule set forth in Section
17.1(b) above, provided that (i) Seller shall have a
minimum time period (the "Minimum Period") of
thirty-one (31) days after each of ▇▇▇▇▇ #▇, #▇, #▇
and #6 is Mechanically Complete and twenty-seven (27)
days after each of Units #2 and #3 is Mechanically
Complete, as shown in the EPC Project Schedule
attached to this Contract as Appendix H (commissioning
of Units #2 and #3 on fuel oil to be delayed until
after Commercial Operation) for inspecting the Unit
and its installation, the performance of pre-testing,
startup, commissioning, correction of discovered
problems, tuning, verification that the Unit is in
proper adjustment and condition to begin Acceptance
Testing and the performance of Acceptance Testing by
Buyer's EPC Contractor (extended for any time periods
during such Minimum Period when Seller reasonably
needs to perform services or tests on such Unit and
does not have such access and availability to such
Unit, consistent with the EPC Project Schedule),
prior to the expiration of which no liquidated damages
shall accrue under this Section 17.1(b). Seller shall
notify Buyer's EPC Contractor, in writing, in the
event that, as provided in the immediately
38
CONFIDENTIAL
preceding sentence, Seller believes that it has not
had the access to such Unit which it reasonably needs
and Buyer's EPC Contractor shall have 24 hours in
which to cure such problem by providing such access to
Seller. Buyer shall cause the EPC Contractor to
provide Seller with written notice when each Unit is
Mechanically Complete, and the Minimum Period shall
not commence until Seller has received such notice.
Any modifications to the EPC Project Schedule made by
the EPC Contractor shall provide Seller with durations
for the performance of Seller's activities during the
Minimum Period, which are comparable to or greater
than the durations available under the original EPC
Project Schedule attached as Appendix H. If, prior to
Commercial Operation of a Unit, Seller recommends
repair activities for a Unit which Buyer's EPC
Contractor has the responsibility to perform, Seller
shall not be charged for liquidated damages for delay
in achieving Commercial Operation of such Unit for any
period of time which is longer than the normal period
of time which would be required to accomplish such
repairs or for any period of time after such repairs
are completed which is longer than reasonably
necessary to prepare such Unit for testing or
retesting. In connection with Seller's performance of
Services under this Contract, including work performed
by Seller during the Minimum Period, Seller shall work
in conjunction with Buyer's EPC Contractor to
coordinate all activities in order to minimize the
total time required for the achievement of Commercial
Operation. Any liquidated damages which accrue under
this Section 17.1(b)(ii) shall be in addition to any
liquidated damages which may accrue under Section
17.1(a) or Section 17.1(b)(i).
In the event that liquidated damages are to be paid to Buyer
pursuant to this Section 17.1(b), such liquidated damages
shall continue to accrue for a Unit for each day until the
earlier of (1) Commercial Operation for such Unit is achieved
or (2) Seller, having (i) achieved the Interim Performance
Requirements for such Unit, (ii) satisfied the exhaust
emission requirements as measured by CEMS in accordance with
the requirements of Appendix C (compliance testing not
required prior to this date), (iii) satisfied the
Demonstration Test Requirements (excluding an Evaporation
Cooler Test), and (iv) successfully completed a ten (10) hour
availability test requirement for such Unit, as described in
Section 7.0 of Appendix C, elects to stop the accrual of
liquidated damages under this Section 17.1(b) by making an
election under Section 17.2(d). "Commercial Operation" means
the satisfaction of all requirements of applicable tests
required under the EPC Agreement for Commercial Operation of a
Unit, as determined under the EPC Agreement. Buyer shall cause
the contractor under the EPC Agreement to cooperate with
Seller to provide timely information, including an Acceptance
Testing schedule during the Minimum Period, to Seller
concerning the Scheduled Commercial Operation Date for each
Unit under the EPC Agreement, including any changes to such
dates within a reasonable time after such changes. In the
event that the aggregate amount of liquidated damages charged
to Seller under
39
CONFIDENTIAL
Section 17.1(b) exceeds the aggregate amount of liquidated
damages paid by the EPC Contractor under the EPC Agreement
for failing to timely achieve Commercial Operation, as
defined in the EPC Agreement, the amount of liquidated
damages charged to Seller under Section 17.1(b) shall be
reduced to such amount paid by the EPC Contractor, and Buyer
shall, if necessary, refund any excess payments to Seller.
In the event that Seller is the primary cause of delay in
the achievement of Commercial Operation of a Unit and the
maximum liquidated damages for delay in achieving Commercial
Operation under this Section 17.1 have accrued, or the delay
in the achievement of Commercial Operation of a Unit caused
by Seller exceeds one (1) year, for whatever reasons,
including delay in Shipment or Delivery of the Unit, Seller
shall be in material breach for substantial nonperformance
of this Contract. Upon a material breach for substantial
nonperformance pursuant to this Section 17.1, Buyer may
pursue any and all remedies available to Buyer, at law or in
equity, including termination of this Contract with respect
to such Unit at any time thereafter without payment of any
Cancellation Charge, and the filing of an action for damages
in addition to any previously accrued liquidated damages
relating to such Unit, caused by such material breach,
subject only to the limitation of liability set forth in
Section 13.1 and the exclusion of damages set forth in
Section 13.2, provided that Section 13.2 shall not restrict
Buyer from the recovery of damages for any additional direct
costs arising from the completion of the performance
required under this Contract, whether by another party or by
Buyer.
(c) ACCRUAL OF LIQUIDATED DAMAGES UNDER SECTIONS 17.1. Liquidated
damages shall accrue pursuant to Section 17.1(a) beginning on
the Scheduled Shipment Date or the Scheduled Delivery Date for
each Unit, as applicable. Liquidated damages, if any,
applicable pursuant to Section 17.1(b) shall be determined by
Buyer within thirty (30) days after Commercial Operation of a
Unit and shall be deemed to have accrued upon the notification
to Seller, in accordance with Section 22.7, of the amount of
such liquidated damages and the basis for such determination;
provided that in the event that Commercial Operation of a Unit
is delayed beyond ninety (90) days after the Scheduled Date of
Commercial Operation for such Unit as a result of delays
caused by Seller or Commercial Operation of a Unit fails to
occur within twelve (12) months of the date of the Delivery of
a Unit, Buyer may, at any time thereafter, notify Seller of
the amount of liquidated damages, if any, applicable to Seller
under Section 17.1(b) and such liquidated damages shall be
deemed to have accrued on such date of notification.
(d) AGGREGATION OF LIQUIDATED DAMAGES. The amounts specified in
the schedule set forth in Section 17.1(a), when aggregated for
all days of late Shipment or Delivery, as applicable, plus the
amounts specified in the schedule set forth in Section 17.1(b)
when aggregated for all Units and all days of delay in
Commercial Operation for all Units represent the aggregate
maximum liability of Seller for late Shipment or Delivery, as
applicable, under Section 17.1(a) and for delay in Commercial
Operation under Section 17.1(b).
40
CONFIDENTIAL
(e) LIMITATION. Seller's total aggregate liability for
liquidated damages under this Section 17.1 for all Units,
together with any payments made pursuant to Section 17.2(e),
shall not exceed thirty percent (30%) of the Total
Contract Price.
17.2 PERFORMANCE.
(a) PERFORMANCE GUARANTEES. If Buyer elects to conduct Acceptance
Testing, then each of the Units shall satisfy the Liquidated
Damage Performance Guarantees set forth in Section 1.0 of
Appendix C, the Performance Guarantees set forth in Section
4.0 of Appendix C, the Demonstration Test Requirements set
forth in Section 6.0 of Appendix C, and the Availability Test
Requirements set forth in Section 7.0 of Appendix C. Seller
may observe any preliminary tests including standard start-up
tests made by Buyer, for the purpose of verifying that the
Unit is in proper adjustment and condition to undergo
Acceptance Testing.
(b) PERFORMANCE LIQUIDATED DAMAGES. With respect to the Liquidated
Damage Performance Guarantees, it is agreed that Buyer's loss
would be difficult to determine in the event that one or more
of the Units fails to satisfy the Liquidated Damage
Performance Guarantees. Accordingly, Seller and Buyer agree as
a predetermined reasonable and exclusive remedy (provided that
with respect to Net Equipment Electrical Output and Net
Equipment Heat Rate, the Units must achieve the Performance
Minimums before liquidated damages become the exclusive
remedy) for any such loss, Seller shall pay to Buyer for
liquidated damages and not as a penalty, sums based upon the
following items:
(i) NET EQUIPMENT ELECTRICAL OUTPUT - [*] for each
kilowatt that the actual Net Equipment Electrical
Output (using an aggregated number for all Units
based upon testing of all Units located at the
Project) is less than the guaranteed Net Equipment
Electrical Output set forth in Section 1.1 of
Appendix C.
(ii) NET EQUIPMENT HEAT RATE - [*] for each BTU per
kilowatt hour per Unit that the actual Net Equipment
Heat Rate (using an average number based upon testing
of all Units located at the Project Site), when
tested on natural gas, is greater than the guaranteed
Net Equipment Heat Rate set forth in Section 1.2 of
Appendix C, plus [*] for each BTU per kilowatt hour
per Unit that the actual Net Equipment Heat Rate
(using an average number based upon testing of all
Units located at the Project Site), when tested on
fuel oil, is greater than the guaranteed Net
Equipment Heat Rate set forth in Section 1.2 of
Appendix C.
(c) ACCEPTANCE TESTING.
(i) TESTING PROCEDURES. Buyer may conduct Acceptance
Testing in order to
41
CONFIDENTIAL
determine whether the Liquidated Damage Performance
Guarantees, the Performance Guarantees, the
Demonstration Test Requirements, and the Availability
Test Requirements have been satisfied. Such testing
shall be conducted by Buyer or on Buyer's behalf and
may be witnessed by Seller. Seller shall develop the
detailed test procedures for initial testing and
potential retesting and obtain Buyer's review,
comment, and approval not later than October 31,
2000; provided that test procedures for the Utility
Tests shall be developed on Buyer's behalf by the EPC
Contractor as set forth in Section 8.0 of Appendix C.
For all Acceptance Testing performed under this
Contract, Buyer (or, as applicable, the EPC
Contractor on Buyer's behalf) shall at no cost to
Seller: (i) make the Units available at the times,
loads and conditions necessary for proper testing,
(ii) provide all instrumentation, labor, operators,
technicians, fuel and consumables required to perform
Acceptance Testing and to read and record the test
data, (iii) provide fuel and consumables in
accordance with the Specifications and (iv) conduct
the Performance Tests, Demonstration Tests, Emissions
Test, Availability Test and Utility Tests in
accordance with test procedures approved by Buyer and
calculate the test results. Seller, based upon
project information provided by Buyer, estimates that
[*] of fuel will be consumed during operation of the
Units in connection with the installation, start up,
commissioning, Acceptance Testing, diagnostic
testing, and retesting of the Units and Seller will
perform the Services under this Contract so as to
minimize the potential use of fuel in excess of such
estimated amounts. Seller shall have no liability for
fuel costs associated with the Project. Seller shall
(i) have the right of representation at all
Acceptance Testing, (ii) have access to all data
resulting from the Acceptance Testing, and (iii) be
promptly furnished with a copy of the test data and
have the right to review and comment on the
calculations used to determine the test results.
(ii) DIAGNOSTIC TESTING AND REMEDY If results of any
Acceptance Testing indicate that any of the
Liquidated Damage Performance Guarantees, the
Performance Guarantees, the Demonstration Test
Requirements, or the Availability Test Requirements
have not been satisfied, Buyer (or the EPC Contractor
on Buyer's behalf) will, at Seller's request, conduct
diagnostic tests (which may include tests to
determine the efficiency of the groups of blading in
each turbine element) to determine the cause(s) of
the failure and the expedient remedial action. With
respect to such diagnostic tests, Seller will at its
expense (i) provide test instrumentation for the
period of the tests, (ii) provide engineering
direction and labor for installation of the test
instrumentation and for conducting the tests, and
(iii) analyze the test data from such tests. With
respect to such diagnostic tests, Buyer (or the EPC
Contractor on Buyer's behalf) will at its expense (i)
provide fuel for the tests, (ii) provide sufficient
load during the tests, (iii) operate the Units during
the tests, and (iv) read and record the test data.
Seller shall, at its
42
CONFIDENTIAL
expense, using all reasonable efforts, attempt to
remedy the failure by repair, adjustment or
replacement of the Equipment as Seller deems
necessary to correct such failure.
(iii) RETESTING. If Seller has completed its attempt to
remedy the failure of the Equipment to satisfy the
Liquidated Damage Performance Guarantees, the
Performance Guarantees, the Demonstration Test
Requirements, or the Availability Test Requirements,
the Parties shall as soon as practicable after the
date of re-synchronization following completion of
Seller's remedy, reperform Acceptance Testing.
Reperformance of Acceptance Testing shall occur as
soon as reasonably possible following notice from
Seller during the Retest Period that a Unit is again
ready for Acceptance Testing. With respect to such
Acceptance Testing, Seller will (i) provide test
instrumentation for the period of the tests, (ii)
provide technical guidance and assistance during the
tests, and (iii) calculate the tests results.
Following any failure of the Equipment to satisfy any
of the Liquidated Damage Performance Guarantees, the
Performance Guarantees, the Demonstration Test
Requirements, or the Availability Test Requirements,
Seller shall continue to use all reasonable efforts
to satisfy the Liquidated Damage Performance
Guarantees, the Performance Guarantees, the
Demonstration Test Requirements, and the Availability
Test Requirements in accordance with the preceding
procedures of this Section 17.2(c), provided that
upon satisfying all of the Performance Guarantees
(other than the Emissions Test, if delayed),
the Demonstration Test Requirements (other than the
Combustion Turbine Evaporative Cooler portion, if
delayed), and the Availability Test Requirements and
achieving all of the Interim Performance
Requirements, Seller may elect to proceed in
accordance with Section 17.2(d). Notwithstanding any
provision in this Contract to the contrary, Buyer
reserves the right to require Seller to reconduct any
Acceptance Testing which Buyer reasonably
deems necessary after any changes, adjustments or
modifications are made to the Equipment by Seller, in
order to confirm or establish the final test results.
Subject to the right of Seller to elect pursuant to
Section 17.2(d), and Buyer's right to terminate this
Contract pursuant to Section 17.2(f), Seller shall be
required to continue diagnostic testing, remedy and
retesting of the Units until all of the Performance
Guarantees, the Demonstration Test Requirements, the
Availability Test Requirements, and the Performance
Minimums have been satisfied.
(d) SELLER'S ELECTION TO REDUCE LIQUIDATED DAMAGES FOR COMMERCIAL
OPERATION. In the event that after completion of Acceptance
Testing, a Unit has (i) achieved the Interim Performance
Requirements, (ii) satisfied the exhaust emission requirements
as measured by CEMS in accordance with the requirements of
Appendix C (compliance testing not required prior to this
date), (iii) satisfied the Demonstration Test Requirements
(excluding an Evaporation Cooler Test), and
43
CONFIDENTIAL
(iv) successfully completed an ten (10) hour availability test
requirement, as described in Section 7.0 of Appendix C, but
has failed to satisfy all of the Liquidated Damage Performance
Guarantees, Seller may elect to stop the accrual of liquidated
damages under Section 17.1(b) by delivering written notice to
Buyer under this Section 17.2(d) of such election, which
notice shall include a statement that the Unit has achieved
the Interim Performance Requirements based upon the results
of the most recent Performance Tests and setting forth the
values for Net Equipment Heat Rate and Net Equipment
Electrical Output achieved by such Unit. For purposes of a
Unit satisfying the Interim Performance Requirements for Net
Equipment Heat Rate and Net Equipment Electrical Output in
order to stop the accrual of liquidated damages under Section
17.1(b), such Unit will be tested individually and must
satisfy each of the Net Equipment Heat Rate Interim
Performance Requirement and the Net Equipment Electrical
Output Interim Performance Requirement individually, and Buyer
shall calculate the performance liquidated damages which would
otherwise be due with respect to such Unit based upon such
values for Net Equipment Heat Rate and Net Equipment
Electrical Output ("Potential Liquidated Damages"), but such
liquidated damages shall not be deemed to have accrued as a
result of such election. Notwithstanding the immediately
preceding sentence, for purposes of finally calculating
liquidated damages under this Contract, Net Equipment Heat
Rate will be determined as an average of all Units and Net
Equipment Electrical Output will be determined as an aggregate
of all Units. After making an election under this Section
17.2(d), Seller shall use all reasonable efforts to cause such
Unit to satisfy all of the Liquidated Damage Performance
Guarantees making such changes and adjustments to the Unit as
Seller deems necessary and diligently retesting until all of
the Liquidated Damage Performance Guarantees for such Unit
have been satisfied or until one hundred eighty (180) days
have expired from the date of the notification, whichever
occurs first ("Retest Period"). As a condition to proceeding
under this Section 17.2(d), Seller agrees that Seller's remedy
and testing will not unreasonably interfere with the normal
and continuous operation of the Unit during the Retest Period
and that the cost of all changes, adjustments and retesting,
excluding fuel and operating expenses, shall be at Seller's
expense. If the Retest Period has elapsed and the Unit has
failed to satisfy all of the Liquidated Damage Performance
Guarantees, Buyer may terminate Seller's remedy and retesting
activities or require Seller to continue remedy and testing
activities for an additional period of up to one hundred
twenty (120) days under the same provisions and procedures
which governed the Retest Period. If Buyer terminates Seller's
remedy and retesting activities, liquidated damages relating
to the Liquidated Damage Performance Guarantees shall be
finally determined in accordance with Section 17.2(f). If
Buyer extends the time for remedy and retesting, Seller shall
make changes and adjustments to the Unit as Seller deems
necessary to satisfy the Liquidated Damage Performance
Guarantees and shall use all reasonable efforts and shall
diligently remedy and retest until all of the Liquidated
Damage Performance Guarantees are satisfied or until such
extension has expired, whichever comes first ("Extended Retest
Period"). The cost of any
44
CONFIDENTIAL
such changes, adjustments and retesting, excluding fuel and
operating expenses, shall be at Seller's expense. If at the
end of such Extended Retest Period, the Equipment has failed
to satisfy all of the Liquidated Damage Performance
Guarantees, Buyer shall terminate retesting and liquidated
damages relating to the Liquidated Damage Performance
Guarantees shall be finally determined in accordance with
Section 17.2(f). If during the Retest Period or the Extended
Retest Period, Buyer operates a Unit more than a total of two
hundred fifty (250) hours to satisfy the requirements of the
Power Purchase Agreement, the Liquidated Damage Performance
Guarantee values will be adjusted in accordance with a
degradation schedule provided in the Acceptance Test
procedures pursuant to Appendix C of this Contract.
(e) MODIFIED LIQUIDATED DAMAGES. During any Retest Period and
Extended Retest Period pursuant to Section 17.2(d),
Buyer and Seller shall, in good faith, coordinate
the availability of Unit(s) for diagnostic testing,
remedy or retesting, so as to permit Seller to
perform such diagnostic testing, remedy or retesting
at times when Buyer would not otherwise operate such
Units under the Power Purchase Agreement. Seller
shall be required to pay modified liquidated damages
only if diagnostic testing, remedy or retesting
during the Retest Period and any Extend Retest
Period causes a Unit to be unavailable to Buyer for
generation of power under the Power Purchase
Agreement for periods in excess of the periods
described in the immediately preceding sentence.
Liquidated damages, if applicable, shall be
calculated on a daily basis with respect to each day
or part thereof that such Unit was unavailable to
Buyer because of diagnostic testing, remedy or
retesting, during the entire period, using the
following formula (this value shall not be less than
zero):
$/Day x (Hours Not Available/24)
The $/Day in the above formula is the full daily
amount of liquidated damages as stipulated in
Section 17.1(b) and considering the number of days,
if any, previously used in such schedule. Hours Not
Available are the actual hours during which Buyer
was prevented from earning revenue from such Unit
during such Day becuase of Seller's activities.
(f) FAILURE OF PERFORMANCE TESTS. If Seller has achieved the
Performance Minimums but failed to satisfy all of the
Liquidated Damage Performance Guarantees with respect to a
Unit, Unit Performance Liquidated Damages shall be
calculated by Buyer in accordance with Section 17.2(b) based
upon the test results from the most recent Performance
Tests, provided that if Seller has not elected to proceed in
accordance with Section 17.2(d), Seller shall use reasonable
commercial efforts to satisfy the Liquidated Damage
Performance Guarantees for a period of at least thirty (30)
days. Unit Performance Liquidated Damages for each Unit
(based upon the most recent performance tests) for failure
to satisfy any Liquidated Damage Performance Guarantees, if
not previously satisfied, shall
45
CONFIDENTIAL
accrue under this Contract on the earlier of (i) such time
as Seller, having satisfied the Performance Minimums and
having used reasonable commercial efforts to satisfy the
Liquidated Damage Performance Guarantees for a period of at
least thirty (30) days, has notified Buyer that it accepts
the results of the most recent Performance Test for such
Unit as the Final Test Values, (ii) if written notice is
delivered to Buyer pursuant to Section 17.2(d), at the end
of any period for remedy and testing of a Unit allowed
pursuant to Section 17.2(d), or (iii) ninety (90) days
having passed since the beginning of initial Acceptance
Testing for a Unit and Seller, having satisfied the Interim
Performance Requirements but failed to achieve the
Liquidated Damage Performance Guarantees for such Unit, has
not elected to proceed pursuant to Section 17.2(d). In the
event that Seller, having been permitted the opportunity to
exercise all reasonable efforts to achieve the Performance
Minimums and satisfy the Performance Guarantees, the
Demonstration Test Requirements, and the Availability Test
Requirements for a Unit for a period not to exceed one
hundred sixty (160) days after the beginning of initial
Acceptance Testing, is unable to achieve all of the
Performance Minimums and to satisfy each Performance
Guarantee, each Demonstration Test Requirement, and each
Availability Test Requirement for a Unit, Buyer may declare
that there has been a material breach and substantial
nonperformance of this Contract with respect to such Unit
and Buyer may thereafter pursue any and all remedies
available to Buyer, at law or in equity (including
termination of this Contract with respect to such Unit
without payment of any Cancellation Charge and the filing of
an action for damages, in addition to any previously accrued
Unit Performance Liquidated Damages, caused by such material
breach and substantial nonperformance), subject only to the
limitation of liability set forth in Section 13.1 and the
exclusion of damages set forth in Section 13.2, provided
that Section 13.2 shall not restrict Buyer from the recovery
of damages for any additional direct costs arising from the
completion of the performance required under this Contract,
whether by another party or by Buyer. In any event, Seller
shall be deemed to have satisfied its obligations under this
Section 17.2 with respect to any Unit upon such Unit
satisfying or achieving the Liquidated Damage Performance
Guarantees, the Performance Guarantees, the Demonstration
Test Requirements, and the Availability Test Requirements
for such Unit. At such time as all of the Units have
accomplished one of the following:
(i) achieved Substantial Completion, or
(ii) completed testing and retesting under a Section
17.2(d) election, or
(iii) satisfied the Performance Minimums and all other
requirements of Acceptance Testing but Seller, in the
absence of a 17.2(d) election, having tried for at
least thirty (30) days after completion of initial
Acceptance Testing to achieve the Liquidated Damage
Performance Guarantees and having not achieved the
Liquidated Damage Performance Guarantees has elected
to accept Unit Performance Liquidated Damages at the
current
46
CONFIDENTIAL
performance level,
final liquidated damages shall be finally determined for all
of the Units based upon Net Equipment Heat Rate determined as
an average of all Units and Net Equipment Electrical Output
determined as an aggregate of all Units and final liquidated
damages shall be adjusted on an equitable basis and paid in
accordance with Section 17.6. Unit Performance Liquidated
Damages for each Unit shall be calculated based upon
performance tests performed on each Unit as a condition to
achieving Substantial Completion of such Unit and the results
of such tests shall be used for all aggregate calculations of
final liquidated damages (without any requirement to repeat
such performance tests), except that Unit Performance
Liquidated Damages for Units #2 and #3 shall be initially
calculated without the Deferred Tests for such Units and Unit
Liquidated Damages for Units #2 and #3 shall be recalculated
as such time as the Deferred Tests are completed for such
Units.
(g) LIMITATION. Seller's total aggregate liability for liquidated
damages under this Section 17.2, excluding any payments made
pursuant to Section 17.2(e), shall not exceed thirty percent
(30%) of the Total Contract Price.
17.3 DOCUMENTATION LIQUIDATED DAMAGES. In the event that the Project
specific documentation, in reasonable form and substance for the power
industry, identified by the initials ▇.▇. in the left margin next to
the documents listed in Appendix G is not provided by the applicable
dates set forth in Appendix G due to causes not excused by the
provisions of this Contract, Seller shall pay to Buyer daily liquidated
damages in the amount of [*] per day for each late document until such
documentation is provided; not to exceed in the aggregate an amount of
[*] per day, regardless of the number of late documents. Seller's
liability for liquidated damages pursuant to this Section 17.3 shall
not exceed [*]. Daily liquidated damages shall accrue under this
Section 17.3 beginning upon the applicable dates set forth in Appendix
G.
17.4 LIMITATION OF LIQUIDATED DAMAGES. Seller's total aggregate
liability for liquidated damages under this Contract shall not exceed
thirty five percent (35%) of the Total Contract Price.
17.5 EXCLUSIVE REMEDY. If the Units achieve all of the Performance Minimums,
Seller's liability for liquidated damages with respect to such Units
shall be the exclusive remedy of Buyer and the sole liability of Seller
for an unexcused failure of the Seller to comply with the Liquidated
Damage Performance Guarantees and the requirements of this Contract in
Section 17.3 with respect to such Units which result in liquidated
damages, whether based in contract, in tort (including negligence and
strict liability), or otherwise. In the event liquidated damages for
failure to meet all of the Liquidated Damage Performance Guarantees or
the requirements of Section 17.3 with respect to the Units are paid by
Seller or by refund in accordance with Section 17.6, Seller's
Liquidated Damage
47
CONFIDENTIAL
Performance Guarantees or the requirements of Section 17.3, as
applicable, shall be deemed met at the level of performance actually
achieved by such Units and Seller's obligations with respect to such
Liquidated Damage Performance Guarantees and Section 17.3 shall
terminate with respect to such Units. Payment of liquidated damages
shall not relieve Seller of its obligations to repair or replace as
provided in Section 10.4 and Seller's obligations arising under
Section 13.3 except, after testing by Seller is completed, with
respect to those specific defects or deficiencies in a Unit for which
such liquidated damages have been paid.
17.6 APPLICATION OF TOTAL CONTRACT PRICE REDUCTIONS As any liquidated
damages accrue pursuant to Article 17, Buyer may invoice Seller for the
amount of such liquidated damages and Seller shall pay to Buyer the
amount invoiced within thirty (30) days of the date invoiced by Buyer,
provided that Buyer, upon written notice to Seller of the amount of
liquidated damages which have accrued, may withhold or cause to be
withheld, such amount of liquidated damages from any payments remaining
due to Seller under this Contract. If the aggregate Unit Performance
Liquidated Damages paid by Seller exceeds the final liquidated damages
determined as set forth in Section 17.2(f), Buyer shall pay to Seller
such excess amount within thirty (30) days of the final determination.
Any amount of liquidated damages which is not paid when due shall
accrue interest at an annual rate of interest equal to the prime rate
of The Chase Manhattan Bank, in effect on the due date plus one percent
(1%). The term Total Contract Price, for the purposes of determining
all limitations on liquidated damages or liability as provided in this
Contract, shall mean the sum of [*] unless the Total Contract Price is
modified pursuant to Section 3.5 or Article 9. The amount set forth in
the preceding sentence shall not be changed by reason of any liquidated
damages which may be withheld from payments due to Seller pursuant to
this Article 17.

22.1 ASSIGNMENT.
(A) ASSIGNMENT TO PROJECT DEVELOPER OR OWNER. Buyer may assign any or
all of its rights or obligations under this Contract to an
affiliate of Buyer, provided such assignee has adequate resources
(as determined by Seller in the exercise of its reasonable
judgment) to fulfill those obligations of Buyer which are
assigned, and further provided such assignee agrees to be bound
by all of the protections and limitations afforded Seller under
this Contract and any defaults of Buyer existing at such time are
cured. Upon completion of such assignment and the delivery of an
assumption agreement (in a form reasonably satisfactory to
Seller) executed by such assignee to Seller, Buyer shall be
released from any and all obligations and liabilities therefor
under this Contract which are assumed by the assignee, provided,
however, Buyer shall not be released from those obligations, if
any, which Buyer elects to reserve from such assignment.
Notwithstanding any provision of this Contract to the contrary,
Buyer and Buyer's assignee, if applicable, shall have the
absolute right, without the consent of Seller, to assign this
Contract, or any rights reserved by Buyer after assignment,
including any licenses granted hereunder pursuant to Section 6.4,
to the Project lenders for collateral security purposes. Seller
will have the right to assign any part of its obligations under
this Contract to any of its subsidiaries or affiliates, in which
case Seller will guarantee the performance of such assignee.
(b) ASSIGNMENT TO CONTRACTOR. In addition to the rights of assignment
under Section 22.1(a), Buyer or Buyer's assignee under Section
22.1(a) may assign this Contract to a third party contractor that
has entered into an agreement with Buyer or such assignee for the
construction of the Project ("Contractor Assignee"), provided
such Contractor Assignee has adequate resources (as determined by
Seller in the exercise of its reasonable judgment) to fulfill
those duties or rights of Buyer or Buyer's assignee under Section
22.1(a) which are assigned and provided such Contractor Assignee
agrees to be bound by all of the protections and limitations
afforded Seller under this Contract and any defaults of Buyer or
Buyer's assignee under Section 22.1(a) existing at such time are
cured. Those rights which are reserved to Buyer or Buyer's
assignee under Section 22.1(a) pursuant to the terms of this
Contract and Appendix M are not assigned to such Contractor
Assignee. Upon the delivery of an assumption agreement (in a form
reasonably satisfactory to Seller) executed by such Contractor
Assignee to Seller, Buyer or Buyer's Assignee under Section
22.1(a), as the case may be, shall be released from any and all
obligations and liabilities therefor under this Contract which
are assumed by the Contractor Assignee, provided, however, Buyer
or Buyer's assignee under Section 22.1(a) is not released from
those obligations which are identified in this
53
CONFIDENTIAL
Contract and in Appendix M as obligations retained by Buyer. In
the event of the delay or cancellation of the Project after this

2.2 GAS TURBINE MECHANICAL DESCRIPTION
The gas turbine output flange is located at the compressor
end of the rotor assembly to provide "cold end" drive. This
feature substantially improves alignment control and
provides an axial exhaust to optimize the plant arrangement
for combined cycle or waste heat recovery applications. The
generator is connected to the gas turbine through a solid
coupling. The direction of rotation is counter-clockwise
when facing the direction of airflow through the gas
turbine.
[GRAPHIC OMITTED]
The gas turbine has an eighteen stage axial flow compressor
with modulated inlet guide vanes. Interstage extraction is
used for turbine nozzle and wheelspace cooling.
A reverse flow, fourteen chamber combustion system is
utilized with multiple fuel nozzles per chamber. Redundant
spark plugs and flame detectors are a standard part of the
combustion system with crossfire tubes connecting each
combustion chamber to adjacent ▇▇▇▇▇▇▇▇. If required, water
injection can be introduced for NOx emissions control.
Transition pieces are effectively cooled by air impingement.
Thermal barrier coatings are applied to the inner walls of
the combustion liners for smoother temperature gradients.
The gas turbine has three turbine stages with the first and
second stage nozzles and buckets being air cooled. The
buckets are designed with long ▇▇▇▇▇▇ to isolate the turbine
wheel rim from the hot gas path. Precision cast buckets are
used for each turbine stage with the second and third stages
incorporating an integral tip shroud for better gas path
leakage control. All turbine buckets are
coated to provide corrosion resistance. The turbine section
is coupled to an axial diffuser with optimum pressure
recovery for higher thermal efficiency.
The rotor is a two bearing single shaft design with high
torque capability. It incorporates internal cooling and
thermal response control in the turbine section. Both the
compressor and turbine sections are constructed of
individually rabbeted discs held with through bolts. For
field changeout, the unit rotor is handled as one piece.
The turbine and compressor casings are horizontally split
for ease of inspection and maintenance. For each combustion
chamber, the liners and transition pieces can be
individually changed out. Borescope holes are located in the
compressor, combustion and turbine sections to facilitate
visual inspection.
2.2.1 COMPRESSOR CLEANING
2.2.1.1 ON-LINE/OFF-LINE COMPRESSOR WATER WASH
Compressor water washing is used to remove fouling deposits
and to restore performance. Fouled compressors result in
reduced air flow, lower compressor efficiency, and lower
compressor pressure ratio. Compressor cleaning may also slow
the progress of corrosion, thereby increasing blade life and
reducing the contribution of corrosion products to the
formation of fouling deposits. On-line cleaning is the
process of injecting cleaning solution into the compressor
while running at full speed and some percentage of load.
Off-line cleaning is the process of injecting cleaning
solution into the compressor while it is being turned at
cranking speed. The advantage of on-line cleaning is that
washing can be done without having to shut down the machine.
On-line washing, however is not as effective as off-line
washing: therefore on-line washing is used to supplement
off-line washing, not replace it.
The on-base compressor washing feature consists of piping,
nozzles, solenoid valves and software in the turbine control
panel. A compressor water wash can be initiated while the
turbine is either on-line or off-line.
The off-base detergent pumping skid consists of detergent
storage tank, mixing venturi, forwarding pump, enclosure and
freeze protection. One skid is provided for the site
(approximate plan dimensions of 9' x 8').
2.2.1.1.1 ON-LINE MANIFOLD AND NOZZLES
The on-line washing components consist of two piping
manifolds, and spray nozzles (one in the forward bellmouth
and one in the aft bellmouth) and a motor-operated valve
which is also controlled by the turbine control panel. The
turbine control system is equipped with software to perform
an automatic on-line wash by simply initiating the wash from
the turbine control panel.
2.2.1.1.2 OFF-LINE MANIFOLD AND NOZZLES
The off-line washing components consist of a piping
manifold, and spray nozzles in the forward bellmouth, and a
motor-operated valve controlled by the turbine control
panel. Off-line washing is a manual operation because of the
large number of manual valves on the turbine which need to
be manipulated in order to perform an off-line wash.
[GRAPHIC OMITTED]
2.2.1.2 COMBUSTION
A reverse flow, multi chamber (can annular) combustion
system is utilized. Combustion ▇▇▇▇▇▇▇▇ are arranged around
the periphery of the compressor discharge casing. This
system also includes the fuel nozzles, spark plug ignition
system, flame detectors, and crossfire tubes.
Crossfire tubes connect each combustion chamber to adjacent
▇▇▇▇▇▇▇▇ on both sides. Transition pieces connect the
combustion liners to the turbine nozzles Each liner, fuel
nozzle, and transition piece can be individually replaced.
[GRAPHIC OMITTED]
2.2.1.2.1 COMBUSTION ▇▇▇▇▇▇▇▇
The combustion liners are cylindrical. Discharge air from
the axial-flow compressor flows forward along the outside of
the combustion liner, as guided by the flow sleeve. Liner
cooling is achieved via film cooling with annular slots
distributed along the length of the combustion liner.
Backside only cooling is utilized on some DLN combustors.
Thermal barrier coatings are applied to the inner walls of
the combustion liners for longer inspection intervals.
Air enters the combustor through a variety of holes in the
liner. The air, depending on its injection location is
utilized in the actual combustion process, for cooling, or
as dilution to tailor the exhaust gas profile.
2.2.1.2.2 TRANSITION PIECES
Transition pieces direct the hot gases from the liners to
the turbine nozzles. The transition pieces have a circular
inlet for the combustion liners transitioning to an annular
segment at the exit for the turbine nozzle. Seals are
utilized at both connection locations to control leakage
flows.
2.2.1.2.3 SPARK PLUGS
Combustion is initiated by discharge from two electrode
spark plugs each in a different combustion chamber. At the
time of firing, a spark at one or both of these plugs
ignites a chamber.
No LP gas torch ignitor system is required with this design.
2.2.1.2.4 CROSSFIRE TUBES
The combustion ▇▇▇▇▇▇▇▇ are interconnected by means of
crossfire tubes. These tubes enable flame from the fired
▇▇▇▇▇▇▇▇ containing spark plugs to propagate to the unfired
▇▇▇▇▇▇▇▇.
2.2.1.2.5 ULTRAVIOLET FLAME DETECTORS
The control system continuously monitors for presence or
absence of flame. Cooled flame detectors are installed in
several combustors. The detector consists of a small gas
filled tube with two closely spread electrodes. An
electronic package containing a power supply applies a high
DC voltage across the electrodes. When ultraviolet (UV)
radiation is present, it causes a discharge within the tube,
which results in a current pulse and discharge of the power
supply.
The power supply recharges and the discharge process
continues to repeat as long as the UV radiation is present.
The presence of flame is determined by the electronic
package which measures the pulse frequency, and relays the
flame condition to the gas turbine control system. The
"FAILURE TO FIRE" or "LOSS OF FLAME" is indicated on the
control panel.
2.2.1.2.6 DRY LOW NOx COMBUSTION SYSTEM
The Dry Low NOx (DLN) combustor is a single stage multi-mode
combustor capable of operation with either gaseous or liquid
fuel. The burning zone is formed by the combustion liner and
the face of the cap. The majority of the combustion air is
introduced through annular passages (premix ▇▇▇▇▇▇▇▇)
surrounding each of the six fuel nozzles.
[GRAPHIC OMITTED]
The DLN 2.6 fuel system operation is fully automated,
sequencing the combustion system through a number of staging
modes prior to reaching full load. The primary controlling
parameter for fuel staging is the calculated combustion
reference temperature. Other DLN 2.6 operation influencing
parameters available to the operator are inlet guide vane
(IGV) temperature control "ON" or "OFF" and inlet bleed heat
"ON" or "OFF". To achieve maximum exhaust temperature, as
well as an expanded load range for optimal emissions, both
IGV temperature control and inlet bleed heat should be
selected "ON".
[GRAPHIC OMITTED]
Liquid fuel injection is injected at the tip of the fuel
nozzle only. Operation is thus in diffusion mode, with
emissions comparable to a standard GE multi-nozzle
combustor. A water injection passage is integral to the fuel
nozzle and is used for NOx abatement while operating on
liquid fuel.
2.2.1.2.7 CONTINUOUS DYNAMICS MONITORING SYSTEM

tuning the combustion system on a rental basis, and will be
returned after unit commissioning. The system shall consist
of the following (optional):
o Probes

2.2.3 DUAL FUEL SYSTEM
2.2.3.1 FUEL TRANSFER
Fuel is to be in accordance with GE fuel specifications as
indicated in the Reference Specification section of the
proposal.
The gas turbine may be started on either fuel, and transfers
from one fuel to the other may be initiated by the operator
prior to start up or at any time after completion of the
starting sequence. Since gas is usually the primary fuel,
with distillate as a backup, transfers from gas to
distillate can be automatically initiated on low gas supply
pressure, provided that liquid fuel is available, and that
there is adequate time to start the fuel forwarding pump.
Transfer back to the primary fuel is by operator initiation
only, in order to ensure the integrity of the supply and
prevent oscillatory operation if the gas supply pressure is
marginal at the transfer initiation pressure. If liquid fuel
is the primary fuel, this automatic sequence can be switched
to accommodate this.
A typical gas/distillate transfer is illustrated below. The
energy equivalent of the fuel flow as the function of fuel
command is matched between the two fuels, so that equal gas
and liquid commands will result in equal energy release in
the gas turbine combustors. The fuel signal divider then
splits the signal to each fuel system in a manner that
maintains the sum of the two signals equal to the total
required fuel demand.
[GRAPHIC OMITTED]
The transfer sequence is divided into two parts, a line
filling period and the actual transfer. During the first
period, the incoming fuel command is raised to
a level that will allow filling of the system in about
thirty seconds, and the outgoing fuel command is lowered by
an equivalent amount. After fuel has reached the fuel
nozzles, the incoming fuel is ramped up to equal the total
fuel demand, and the outgoing fuel is ramped down to zero.
Since total energy to the gas turbine is held reasonably
constant, load variations for a properly matched and tuned
system are minimal, and generally are less than five percent
of nameplate rating.
The next step in the process involves initiation of the
inactive fuel system purge, if purging is required, and
automatic verification of proper operation. Since purging
results in additional, although limited, fuel being injected
into the turbine to clear the inactive fuel system, there is
potential for a load disturbance at this time if the purge
is initiated too abruptly. Once the system is cleared, the
potential for a load spike disappears. Purge system
sequencing is designed to minimize this effect, and in the
case of liquid fuel nozzle purging, is initiated during the
transfer. This results in random opening of purge check
valves, which has been shown to substantially reduce the
load spikes. The final step in the transfer process is
resetting the NOx control system to meet the needs of the
new fuel.

2.2.5 INLET SYSTEM
2.2.5.1 GENERAL
Gas turbine performance and reliability are a function of
the quality and cleanliness of the inlet air entering the
turbine. Therefore, for most efficient operation, it is
necessary to treat the ambient air entering the turbine and
filter out contaminants. It is the function of the air inlet
system with its specially designed equipment and ducting to
modify the quality of the air under various temperature,
humidity, and contamination situations and make it more
suitable for use. The inlet system consists of the equipment
and materials defined in the Scope of Supply chapter of this
proposal. The following paragraphs provide a brief
description of the major components of the inlet system.
2.2.5.2 INLET FILTRATION
2.2.5.2.1 INLET FILTER COMPARTMENT
The inlet filter compartment sits on a steel support
structure upstream of the gas turbine. The elevated
arrangement provides a compact system and minimizes pickup
of dust concentration near the ground.
The two stage inlet filter is comprised of a prefilter and a
high-efficiency filter. The media-type prefilters provide an
inexpensive, disposable stage of filtration. The prefilters
usually extend the life of high-efficiency filters by a
factor of about three.
The high-efficiency filters use filter medium appropriate
for the site environmental conditions to achieve good
collection efficiency for all particles, including those as
small as 1 micron. Because the collection
efficiency is very high, the air quality downstream is also
high, even when the ambient air is badly contaminated.
The filter elements are contained within a fabricated steel
enclosure which has been specially designed for proper air
flow management and weather protection.
As the outside of the filter elements become laden with
dust, increasing differential pressure is sensed by a
pressure switch in the plenum.
2.2.5.2.2 EVAPORATIVE COOLER
The evaporative cooler is used in applications where
significant operation occurs in the hot months and where low
relative humidities are common. With evaporative cooling,
water is added to the inlet air and, as the water
evaporates, the air is cooled. The amount of water required
for evaporative cooling depends upon the airflow through the
turbine, the temperature and humidity of the ambient air and
the amount of hardness in the water. The exact increase in
power available from the gas turbine is dependent upon the
same site conditions.
The cooler consists of a water distribution system and media
packed blocks made of corrugated layers of fibrous material.
Water is distributed over the blocks through one set of
channels and the air passes over alternate channels. The air
side is wetted by the wicking action of the media. This
system minimizes water carryover.
Water is to be provided per GEK 101944, "Requirements for
Water/Steam Purity in Gas Turbines."
2.2.5.3 INLET SYSTEM INSTRUMENTATION
2.2.5.3.1 INLET SYSTEM DIFFERENTIAL PRESSURE INDICATOR
Standard pressure drop indicator (gauge) displays the
pressure differential across the inlet filters in inches of
water.
2.2.5.3.2 INLET SYSTEM DIFFERENTIAL PRESSURE ALARM
When the pressure differential across the inlet filters
reaches a preset value , an alarm is initiated. This alarm
may signify a need to change the filter elements.
2.2.5.4 INLET DUCTING AND SILENCING
2.2.5.4.1 INLET DUCTING
The inlet ductwork system connects the inlet filter
compartment with the gas turbine compressor inlet plenum.
The ducting is designed to deliver the required air flow to
the compressor while minimizing the pressure drop of the
incoming air stream. There is a stationary trash screen
within the ducting system to prevent the remote possibility
of ingestion of foreign objects. The trash screen can be
accessed for cleaning and inspection through a removable
access panel. The inlet ducting makes use of materials and
coatings in their construction which are designed to
minimize maintenance requirements.
2.2.5.4.2 INLET SILENCING
The noise generated during gas turbine operation is
attenuated by means of absorptive silencing material and
devices built into the inlet system which dissipate or
reduce the acoustical energy to an expected level of 58 dBA
at normal operation and 65 dBA during filter cleaning at 400
feet. The silencer is specifically designed to eliminate the
fundamental compressor tone, and to attenuate the noise at
other frequencies also. The inlet silencer consists of an
acoustically lined duct containing 8 feet of silencing
baffles constructed of a low-density insulating material
which is encapsulated by perforated sheet steel. The
acoustic lining in the walls of the silencer duct and the
walls of the ducting downstream of the silencer have a
similar construction.
2.2.5.4.3 INLET SYSTEM ANTI-ICING PROTECTION
This system features an inlet bleed heat injection manifold
integrated with the inlet silencer.
2.2.6 EXHAUST SYSTEM
The exhaust system arrangement includes the exhaust
diffuser. After exiting the last turbine stage, the exhaust
gases enter the exhaust diffuser section in which a portion
of the dynamic pressure is recovered as the gas expands. The
gas then flows axially into the exhaust system which is not
in GE's scope of supply.
GE is providing an inconel flex-joint expansion joint at the
outlet flange of the exhaust frame which is designed to
interface with internally insulated exhaust diffuser.
2.2.7 ACOUSTICS
Measuring procedures will be in accordance with ASME PTC 36
(near field) and/or ANSI B133.8 (far field).
2.2.8 PAINTING
The exteriors of the turbine compartment, accessory and
liquid fuel/atomizing air modules, generator compartment,
control cab (if supplied), BAC/LCI and accessory base and
other equipment are painted with two coats of alkyd primer
prior to shipment.
The turbine compartment interior is painted with
high-temperature paint. Interiors of all other compartments
are painted.
2.2.9 WIRING
The gas turbine electrical interconnection system includes
on-base wiring, terminal boards, junction boxes, etc. as
well as compartment interconnecting cables. Junction boxes
are selected to meet the environmental requirement of the
Purchaser but are, in general, of steel or cast aluminum
construction. Special environments such as corrosive or
hazardous can be accommodated. Terminal boards within
junction boxes are of the heavy duty industrial type
selected for the particular environment in which the
junction box is located. On-base gas turbine wire
termination uses spring tongue crimped type terminals.
Generator wire terminations are ring type. Control panel
wiring is General Electric type SIS Vulkene insulated
switchboard wire, AWG #▇▇-▇▇ ▇▇▇▇▇▇ ▇▇-▇▇▇▇▇. ▇▇▇▇▇▇ cables
are used as appropriate.
With the exception of cables pre-connected with specific
equipment, the Purchaser or his Installer is responsible for
interconnecting cable purchase, installation, and
connection. GE will supply appropriate connection diagrams
and recommended cable installation procedures for the
turbine and GE furnished off-base equipment. On-base gas
turbine wire installation and termination is performed in
the factory.
2.2.10 MISCELLANEOUS PARTS
As a service to the customer and to facilitate an efficient
installation of the gas turbine, GE provides for shipment of
miscellaneous parts needed during field installation.
Shipment is in a single 96" x 96" x 192" (2438 mm x 2438 mm
x 4877 mm) weather-tight cargo container. The plywood
container, which can be opened from one end, is outfitted
with shelves and bins for parts storage. The container
comprises what amounts to a "mobile stockroom" and is
designed for transport by truck or rail.
Within the container, each part is packed, identified with
its own label or tag, and stowed in an assigned bin or
shelf. A master inventory list furnished with the container
provides the location of each part for ease in locating the
item.
An additional box approximately 60" x 60" x 216" (1524 mm x
1524 mm x 5486 mm) is furnished for the interconnecting
piping.
2.2.10.1 OFF-BASE COOLANT-TO-AIR INDUSTRIAL TYPE COOLING SYSTEM

pressurized coolant system is supplied to dissipate the heat
from the lubrication oil and turbine support legs. It also
cools the flame detectors, atomizing air system and
generator. The following major components are included:

will only require a minimum amount of field inspection of
these components.
All generator wiring, including winding and gas RTD's,
bearing metal and drain TC's, and vibration detection
systems will all be terminated on the main unit with level
separation provided. The standard arrangement will be hard
wired.
Prior to full assembly, the generator stator will receive a
150% pressure test. Following full assembly, a 45 psig seal
oil test will be performed to ensure the seals are seated
properly.
Feed piping between the bearings will be stainless steel and
mounted on the units in the factory to a common header. All
connections to the end ▇▇▇▇▇▇▇ will be assembled. All
assembled piping will be welded without backing rings and a
first pass TIG weld. A full oil flush will be performed
prior to shipping.
Some amount of field assembly will be required but should be
limited to the following:
o Factory fitted bearing drain piping and bearing drain
enlargement (BDE)
-- Matched, marked, and shipped separate
-- Loop seal between BDE and drain tank will be stainless
steel and will ship loose
o Water manifolds will be factory fitted and shipped
separate
o Collector compartment
-- Interconnecting wiring and piping
-- Alignment of collector housing and brush rigging to
collector ring
2.3.1.3 FRAME FABRICATION
The frame is a stiff structure, constructed to be a hydrogen
vessel and to be able to withstand in excess of 200PSI. It
is a hard frame design with its four-nodal frequency
significantly above l20Hz. The ventilation system is
completely self contained, including the gas coolers within
the structure. The gastight structure is constructed of
welded steel plate, reinforced internally by radial web
plates and axially by heavy wall pipes, bars and axial
braces.
A series of floating support rings and core rings are welded
to keybars which in turn will support the core. This allows
the entire core to be spring mounted at twenty locations.
This arrangement isolates the core vibration, resulting from
the radial and tangential magnetic forces of the rotor, by
damping the amplitude and reducing the transmissibility by
20:1 Excessive movement of the core, as may result from out
of phase synchronization, is limited by the use of stop
collars at certain locations circumferential around the
frame. The clearance is designed to allow the spring action
of the bar to be unrestricted during normal operation but to
transmit the load of excessive movement through the
structure prior to yielding of any of the components. This
entire arrangement is in keeping with long standard
practices and experience with similar frame designs which
have proven to be very effective and reliable.
The stator frame is supported on four welded-on feet
attached at the lower portion of the fabrication. All the
weight of the unit and the operating loads are carried
through the structure by the web plates and the wrapper to
the feet. The machined portion of the feet are located 85"
below the centerline of the unit.
2.3.1.4 CORE
The core is laminated from grain oriented silicon steel to
provide maximum flux density with minimum losses, thereby
providing a compact electrical design. The laminations are
coated on both sides to ensure electrical insulation and
reduce the possibility of localized heating resulting from
circulation currents.
The overall core is designed to have a natural frequency in
excess of 170 hertz, well above the critical two-per-rev
electromagnetic stimulus from the rotor. The axial length of
the core is made up of many individual segments separated by
radial ventilation ducts. The ducts at the core ends are
made of stainless steel to reduce heating from end fringing
flux. The flanges are made of cast iron to minimize losses.
The unit will receive periodic pressing during stacking to
ensure compactness, and after stacking the core will receive
a final press in excess of 700 tons.
2.3.1.5 ROTOR
The rotor is machined from a single high alloy steel
forging. The two pole design has 24 axial slots machined
radially in the main body of the shaft. The axial vent slots
machined directly into the main coil slot are narrower then
the main slots and provide the direct radial cooling of the
field copper.
The two retaining rings are of the body mounted design. The
rings will be made of 18 Mn - 18 Cr forged material which
offers excellent protection against stress corrosion
cracking.
The coil wedges are segmented stainless steel. Radial holes
are drilled in the wedges for ventilation passages.
The shaft at the collector is designed to transmit the
torque of an optional starting motor. A shrunk-on coupling
is assembled after the collector rings are on, and it
provides the interface point to the flex-coupling connection
to the motor. The same arrangement and coupling are used
with a static start system when the turning gear is replaced
by a torque converter and starting motor.
2.3.1.6 FIELD ASSEMBLY
The field consists of coils made from high conductivity
copper. Each turn will have slots punched in the slot
portion of the winding to provide direct cooling of the
field. The end turns are of the same cross section as the
slot portion and the entire coil will be pre-assembled with
overlapping brazed joints.
The slot armor used in the slots is a Class "F" rigid epoxy
glass design. An insulated cover is positioned on the bottom
of each slot armor and on top of the subslot vent. The cover
will provide the required creepage between the lower turn
and the shaft. Epoxy glass insulation strips are used
between each coil turn. A pre-molded polyester glass
retaining ring insulation is utilized over the end windings
and a partial amortisseur is assembled under the rings to
form a low resistance circuit for eddy currents to flow. The
rotor is designed to accommodate static start hardware
utilizing full length slot amortisseurs.
The collector assembly incorporates all the features of GE
proven generator packages with slip on insulation over the
shaft and under the rings. The collector rings use a radial
stud design to provide electrical contact between the rings
and the field leads. The rings are designed to handle the
excitation requirements of the design (approximately 2200
amps on cold day operation and 1900 amps at rated
conditions).
The entire rotor assembly, weighing 76,000 pounds is
balanced up to 10% over operating speed.
[GRAPHIC OMITTED]
2.3.1.7 END SHIELD/BEARING
The unit is equipped with end ▇▇▇▇▇▇▇ on each end designed
to support the rotor bearings, prevent gas from escaping and
to be able to withstand a hydrogen explosion in the unlikely
event of such a mishap. The end shield is constructed from
steel plate and it is reinforced to provide the required
strength and stiffness. The split at the horizontal joint
allows for ease of assembly and removal. The horizontal
joints, as well as the vertical face which bolts to the end
structure, are machined to provide a gas tight joint.
Sealing grooves are machined into these joints. These steps
are taken to prevent gas leakage between all the structural
components for pressures up to 45 psig.
The center section of the end ▇▇▇▇▇▇▇ contain the bearings,
oil deflectors and hydrogen seals.. The lower halves of the
bearings are equipped with dual element thermocouples. The
leads are connected through a quick disconnect through the
end shield to allow ease of bearing removal.
A three section inner and a two section outer oil deflector
are bolted into the end shield and provide sealing of the
oil along the shaft. The deflectors are either fabricated or
cast aluminum. All faces of the deflectors have "O" ring
grooves to provide additional protection from oil leaks. All
annular areas formed between the set of teeth are designed
to provide minimum pressure drops and have oil gutters
machined in to prevent oil from backdripping on the shaft.
The hydrogen seal casing and seals, which prevent hydrogen
gas from escaping along the shaft utilize steel babbitted
rings. Pressurized oil for the seals is supplied from the
main oil system header to the seal oil control unit, where
it is regulated. The seal oil control unit is factory
assembled packaged system and is located in the collector
end compartment and includes the following components:
o Differential pressure regulator valve with bypass
o Differential pressure gage (seal oil pressure vs casing
gas pressure) and two differential pressure switches: one
for alarm and one for actuating the DC emergency seal oil
pump
o Shut-off and isolation valves for operation and
maintenance
The connection end bearing and hydrogen seals are insulated
from the rotor to prevent direct electrical contact between
the rotor and the end shield. Both end ▇▇▇▇▇▇▇ will have
proximity type vibration probes. These are located axially
outboard of the bearing. Mounting for velocity type
vibration sensors is also provided on the surface of the
bearing caps.
All exiting wiring from the temperature indication devices
and the insulating test leads are brought out of the unit
through gas tight conex type seals to prevent any chance of
a hydrogen leak.
2.3.1.8 WINDING
The armature winding consists of "Class F" insulated bars.
The winding is a three phase, two circuit design. The bar
ground insulation is protected with a semi-conducting armor
in the slot and our well proven grading system on the end
arms.
The ends of the bars are pre-cut and solidified prior to
insulation to allow strap brazing connections on each end
after the bars are assembled. A resin impregnated insulation
cap is used to insulate the end turn connections.
The bars are secured in the slot with side ripple springs
(SRS) to provide circumferential force and with a top ripple
spring (TRS) for additional mechanical restraint in the
radial direction. The SRS's, TRS's and the wedging system
are well-proven reliable designs. The end winding support
structure consists of glass binding bands, radial rings and
the conformable resin-impregnated felt pads and glass roving
to provide the rigid structure required for system
electrical transients.
[GRAPHIC OMITTED]
2.3.1.9 LEAD CONNECTIONS
All the lead connection rings terminate at the top of the
structure at the excitation end of the unit. Each of the
circuits are connected to the high voltage bushings. The
bushings, which provide a compact design for factory
assembly and shipment, are positioned in the top of the
frame and are offset to allow proper clearances to be
maintained. This configuration also allows connections to
the leads to be staggered and provides ease of bolting and
insulation.
The six high voltage bushings exit the frame at the top.
These bushings are made up of a porcelain insulators
containing silver plated, copper conductors which form a
hydrogen tight seal. The bushings are assembled to
non-magnetic terminal plates to minimize losses. Copper bus
is assemble to the bushings within an enclosure. Customer
connections are made beyond the terminal enclosure and the
specific mating arrangements will be provided within the
enclosure, not inside the generator.
2.3.1.10 LUBRICATION
Lubrication for the generator is supplied from a system in
common with the turbine lubrication system which is
contained in the lubrication module. Lubricant feed and
drain lines are provided as an integral part of the
generator
package. Flanged connections are provided for connection to
piping from the lubrication module.
2.3.1.11 DETRAINING SYSTEM
The air-side seal oil and the generator bearing oil drain to
a bearing drain enlargement mounted under the generator
casing. This bearing drain enlargement is a detraining
chamber and provides a large surface area for detraining the
oil before it is returned to the main oil tank.
Two seal drain enlargements are provided for removing
entrained hydrogen from the oil which drains from the
hydrogen-side seal rings. They are drained through a common
line to a float trap which then drains to the bearing drain
enlargement for further detraining. A high liquid level
alarm switch is provided to detect abnormal oil level in the
seal drain enlargement.
Piping is all factory fitted and the system is well-proven
to assure that no hydrogen can enter into the oil system.
2.3.1.12 HYDROGEN CONTROL CABINET
To maintain hydrogen purity in the generator casing at
approximately 98 percent, a small quantity of hydrogen is
continuously scavenged from the seal drain enlargements and
discharged to atmosphere. The function of the hydrogen
control cabinet is to control the rate of scavenging and to
analyze the purity of the hydrogen gas. The cabinet is
divided into two compartments, the gas compartment and the
electrical compartment, which are separated by a gas-tight
partition.
2.3.1.13 GAS COMPARTMENT

60 HZ, with a short circuit capacity of 42,000 amps RMS
symmetrical at the incoming 480VAC line terminals. The main
protective device will be a Tri break 600 amp, type TB4,
200,000 amp interrupting, 125-400 amp trip, bolt -in
connection.
2.3.1.18 COOLING SYSTEM
The generator is cooled by a recirculating gas stream cooled
by gas-to-water heat exchangers. Cold gas is forced by the
generator fans into the gas gap, and
also around the stator core. The stator is divided axially
into sections by the web plates and outer wrapper so that in
the center section cold gas is forced from the outside of
the core toward the gap through the radial gas ducts, and in
the end section it passes from the gas gap toward the
outside of the core through the radial ducts. This
arrangement results in substantially uniform cooling of the
windings and core.
The rotor is cooled externally by the gas flowing along the
gap over the rotor surface, and internally by the gas which
passes over the rotor and windings, through the rotor
ventilating slots, and radially outward to the gap through
holes in the ventilating slot wedges.
After the gas has passed through the generator, it is
directed to five horizontally mounted gas-to-water heat
exchangers. After the heat is removed, cold gas is returned
to the rotor fans and recirculated.

the generator. The end wall of the enclosure will have
provisions for the flex coupling between the generator and
the starting motor or torque converter to pass through. The
generator end of the enclosure will interface with the
generator and be sealed against the elements.
The enclosure is designed with a removable end wall section
& roof to allow ease of rotor removal without moving the
housing. Position of all the above hardware will be spaced
to allow easy access for maintenance and to prevent any
unnecessary disassembly during rotor removal. Two doors are
provided on the end wall to allow access from either side.
Safety latches are provided on the inside of the doors to
provide easy exit from the enclosure. AC lighting is
standard. One DC light fixture is optional. Fire detectors

--------------------------------------------------------------------------------
2.4 GAS TURBINE CONTROL DESCRIPTION
2.4.1 ▇▇▇▇ V SPEEDTRONIC CONTROL SYSTEM
2.4.1.1 CONTROL SYSTEM
The gas turbine control system, SPEEDTRONIC ▇▇▇▇ V, is a
state-of-the-art Triple Modular Redundant (TMR)
microprocessor control system with a heritage of over 40
years of successful turbine automation. The core of this
system is the three separate but identical controllers
called [R], [S], and [T]. All critical control algorithms,
protective functions, and sequencing are performed by these
processors. In so doing, they also acquire the data needed
to generate outputs to the turbine. Protective outputs are
routed through the [P] module consisting of triple redundant
processors [X], [Y], and [Z], which also provide independent
protection for certain critical functions such as overspeed.
The three control processors, [R], [S], and [T], acquire
data from triple-redundant sensors as well as from dual or
single sensors. The actual number of sensors will depend on
the turbine type. All critical sensors for continuous
controls, as well as protection, are triple-redundant. Other
sensors are dual or single devices fanned out to all three
control processors. The extremely high reliability achieved
by TMR control systems is due in considerable measure to the
use of triple sensors for all critical parameters.
2.4.1.1.1 ▇▇▇▇ V ELECTRONICS
All of the microprocessor-based controls have a modular
design for ease of maintenance. Each module or controller
contains up to five cards, including a power supply.
Multiple microprocessors reside in each controller which
distribute the processing for maximum performance.
Individual microprocessors are dedicated to specific I/O
assignments, application software communications, etc., and
the processing is performed in a real-time, multi-tasking
operating system. Communications between the controller's
five cards is accomplished with ribbon cables and gas-tight
connectors. Communication between individual controllers is
performed on high-speed Arcnet links.
2.4.1.1.2 SHARED VOTING
Software Implemented Fault Tolerance (SIFT) and hardware
voting are utilized by the ▇▇▇▇ V TMR control system. At the
beginning of each computing time frame, each controller
independently reads its sensors and
exchanges this data with the data from the other two
controllers. The median value of each analog input is
calculated in each controller and then used as the resultant
control parameter for that controller. Diagnostic algorithms
monitor a predefined deadband for each analog input to each
controller, and if one of the analog inputs deviates from
this deadband, a diagnostic alarm is initiated to advise
maintenance personnel.
Contact inputs are voted in a similar manner. Each contact
input connects to a single terminal point and is parallel
wired to three contact input cards. Each card optically
isolates the 125 or 24 V dc input, and then a dedicated
80196 processor in each card time stamps the input to within
1 ms resolution. These signals are then transmitted to the
[R], [S], and [T] controllers for voting and execution of
the application software. This technique eliminates any
single point failure in the software voting system.
Redundant contact inputs for certain functions such as low
lube oil pressure are connected to three separate terminal
points and then individually voted. With this SIFT
technique, multiple failures of contact or analog inputs can
be accepted by the control system without causing an
erroneous trip command from any of the three controllers as
long as the failures are not from the same circuit.
Another form of voting is accomplished through hardware
voting of analog outputs. Three coil servos on the valve
actuators are separately driven from each controller, and
the position feedback is provided by three LVDTs. The normal
position of each valve is the average of the three commands
from [R], [S], and [T]. The resultant averaging circuit has
sufficient gain to override a gross failure of any
controller, such as a controller output being driven to
saturation. Diagnostics monitor the servo coil currents and
the D/A converters in addition to the LVDTs.
2.4.1.1.3 PC BASED OPERATOR INTERFACE
The operator interface, [I], consists of a PC, color
monitor, cursor positioning device, keyboard, and printer.
It can be used as the sole operator interface or as a local
maintenance work station with all operator control and
monitoring coming from communication links with a plant
distributed control system (DCS). Operators use the monitor,
cursor positioning device, and keyboard. The keyboard is not
necessary. However, the keyboard is convenient for accessing
displays with dedicated function keys and adjusting
setpoints by entering a numeric value such as 100 mw rather
than issuing a manual raise/lower command. The keyboard is
primarily used for maintenance such as editing application
software or alarm messages. Setpoint and logic commands
require an initial selection, such as the command to engage
the
turning gear, which is followed by a confirming execute
command. The monitor is available in various sizes and
types, and it can be used for desktop mounting, packaged as
a drop-in insert for a control room console, or mounted in a
separate free-standing cabinet.
2.4.1.1.4 DIRECT SENSOR INTERFACE
▇▇▇▇ V input/output (I/O) is designed for direct interface
to turbine and generator devices such as thermocouples,
RTD's , vibration sensors and flame sensors. Direct
monitoring of these sensors eliminates the cost and
potential reliability factors associated with interposing
transducers and instrumentation. In addition, all of the
resultant data visible to the operator from the ▇▇▇▇ V
operator interface and Distributed Control System (DCS)
system via a communication link if desired.
2.4.1.1.5 BUILT-IN DIAGNOSTICS
The ▇▇▇▇ V control system has extensive built-in diagnostics
and includes "power-up", background and manually initiated
diagnostic routines capable of identifying both control
panel, sensor, and output device faults. These faults are
identified down to the board level for the panel, and to the
circuit level for the sensor or actuator component. On-line
replacement of boards is made possible by the ▇▇▇▇ V's
triply redundant design and is also available for those
sensors where physical access and system isolation are
feasible.
2.4.1.1.6 GENERATOR INTERFACE AND CONTROL
The primary point of control for the generator is though the
▇▇▇▇ V operator interface. However, the ▇▇▇▇ V is integrated
with the EX2000 excitation system over an Arcnet local area
network (LAN). Therefore the ▇▇▇▇ V is used to control
megawatt output and the EX2000 is used to control megavar
output. The generator protection panel (GPP) is used to
provide primary protection for the generator. This
protection is further augmented by protection features
located in the EX2000 and the ▇▇▇▇ ▇.
2.4.1.1.7 SYNCHRONIZING CONTROL AND MONITORING
Automatic synchronization is performed by the [X], [Y], and
[Z] cards in conjunction with the [R], [S], and [T]
controllers. The controllers match speed and voltage and
issue a command to close the breaker based on a predefined
breaker closure time. Diagnostics monitor the actual breaker
closure time and self-correct each command. Another feature
is the ability to
synchronize manually via the ▇▇▇▇ V operator interface
instead of using the traditional synchroscope on the
generator protective panel. Operators can choose one
additional mode of operation by selecting the monitor mode,
which automatically matches speed and voltage, but waits for
the operator to review all pertinent data on the CRT display
before issuing a breaker close command.
2.4.1.1.8 ARCHITECTURE
The ▇▇▇▇ V control configuration diagram depicts several
advantages for increased reliability and ease of interface.
For example:
o Multiple unit control from a single [I] which allows any
turbine to be controlled from any [I]
o Back-up display wired directly to [R], [S], and [T]
controllers
o PC interface to plant DCS system
o Hard wire protective signal from [R] [S] [T] controllers
o Additional protective processors [X], [Y], [Z]
The protective block diagram shows the built in
redundancy/reliability of the ▇▇▇▇ V control system. For
example, if there is an overspeed condition requiring a trip
of the unit, the first line of defense would be the primary
overspeed protection via the [R], [S], and [T] controllers.
All three trip signals then pass to the [P] trip card where
two out of three voting occurs prior to sending the
automatic fuel supply trip signal. The secondary overspeed
protection is via the [X], [Y], and [Z] cards which
similarly send their independent trip signals to the [P]
trip card for voting.

2.4.1.2 SCOPE OF CONTROL
The ▇▇▇▇ V control system provides complete monitoring
control and protection for Gas Turbine-Generator and
Auxiliary systems. The scope of control is broken down into
three (3) sections: Control, Sequencing and Protection.

-- Protection
-- Overspeed, redundant electronic
-- Overtemperature (including generator)
-- Vibration
-- Loss of flame
-- Combustion monitor
-- Redundant sensor CO(2) fire protection
-- Low lube oil pressure, high lube oil temperature,
etc.
2.4.1.3 GAS TURBINE PLANT OPERATING MODES
2.4.1.3.1 STARTING/LOADING
All starting is done automatically, with the operator given
the opportunity to hold the start-up sequence at either the
crank (pre-ignition) or fire (post-ignition, pre-accelerate)
points of the start-up. An "Auto" mode selection results in
a start without any holds.
Either before issuing a start command, or during the start,
the operator may make the following selections:
1. Select or disable the automatic synchronization
capability of the ▇▇▇▇ V control. Auto synch utilizes
the proven microsynchronizer first introduced in the
▇▇▇▇ ▇▇ generation of SPEEDTRONIC. The
microsynchronizer provides extremely accurate and
repeatable breaker closures based on phase angle, slip,
the rate of change of slip and the response time of the
breaker which is in the system memory.
2. Select Preselected Load or Base Load. If a selection is
made the unit will automatically load to the selected
point and control there. If no selection is made the
unit will load to a low load referred to as "Spinning
Reserve"
automatically upon synchronization; be it automatic or
manual. The turbine governor is automatically regulated
to maintain the megawatt setting assigned to "Spinning
Reserve".
2.4.1.3.2 OPERATING
Once the unit is on line, it may be controlled either
manually or automatically from the ▇▇▇▇ V control Operator
Interface.
Manual control is provided by the governor raise/lower
control displayed on the operator interface screen.
Automatic operation is switched on when the operator selects
one of three load points (preselect or base) from the
turbine control interface.
For a fully automatic start with automatic loading to base
load, the operator selects the "Auto" operating mode,
enables auto synchronization and selects "Base" load. Given
a "Start" signal, the unit will then start, synchronize and
load to Base load with no further input on the part of the
operator.
2.4.1.3.3 SHUTDOWN
On shutdown, the system will automatically unload and return
to turning gear motor operation. The unit will stay on
turning gear until an operator turns it off. Note: the
operator must insure the unit is sufficiently cool before
shutting off turning gear to avoid temporary rotor bow due
to heat.
2.4.1.4 COMMUNICATIONS
The open architecture of the [I] processor facilitates a
wide range of external communication links. The ▇▇▇▇ V's
internal Arcnet communication link is isolated from external
communication links at the [I] processor.
The External communication link utilizes Ethernet with
TCP-IP protocol to facilitate transmitting of data with
local time tags for alarms and events to the plant level.
Ethernet provides high speed 10 mega baud transmission rates
combined with TCP-IP which is widely used throughout the
world. GE supplies an application layer protocol call GSM
(i.e. GEDS Standard Messages) which supports four classes of
application level messages.
Time synchronization between ▇▇▇▇ Vs, and/or between ▇▇▇▇ Vs
and a DCS enable all time tags to be referenced to a common
source. The [I] operator interface is the common reference
point within the ▇▇▇▇ V control system, and it sends the
time synchronization commands to the ▇▇▇▇ V controllers
where the individual time tags are assigned. Sites with
multiple ▇▇▇▇ Vs can have a master [I] for time
synchronization with the other [I]s acting as slaves. A
failure of the master [I] will initiate an automatic default
to one of the slaves as the new master.
The [I] operator interface is supplied with 50 ft (15 m) of
cable to facilitate convenient location near the ▇▇▇▇ V
panel. However, the communications link provided allows for
remote location of a single interface using up to 1500 ft
(457 m) of cable without repeaters or 9600 ft (2926 m) using
a fiber optic link without repeaters. Multiple operator
interfaces may be used to communicate to a ▇▇▇▇ ▇. This
capability changes the maximum allowable distance of a
remote operator interface. Cable routing between buildings
of this stage link cable requires adequate lightning
protection (i.e., fiber optics).
2.4.1.5 OPERATOR DISPLAYS
Two (2) out of the typical forty (40) available displays are
shown on the following pages. The first screen is the main
menu display. From the main menu all operation/maintenance
and user defined screens can be reached. The main menu
screen is made up of three (3) major areas:
-- List of available displays
-- Alarm field shows the three (3) latest unacknowledged
alarms (Black band near bottom of screen in the
example. Blue is the actual color.)
-- Function control keys (bottom of screen)
[GRAPHIC OMITTED]
The second screen shown is a typical operating screen. Note
that the alarm list and function control key fields are also
shown below the primary display field on this screen.
Control target values are shown in the primary display
field. Selecting and executing commands is very simple. For
example, to go to baseload, you would move the cursor to the
"Baseload" target and click on it. Then before the control
times out, you would move the cursor to the "Execute
Command" target and click on it. The "Execute Command" step
protects against accidental activation of the wrong command
that might occur with a one step (point/click) command.
Signals that require an Execute command in order to be
activated are:
-- Start -- Stop
-- Operation Selection
-- Off
-- Crank
-- Fire
-- Auto
-- Remote
-- Fuel Selection
-- Gas
-- Distillate (Dist)
-- Load Selection
-- Preselected Load
-- Base
-- Guide Vane Control
-- Temp Control Off
-- Temp Control On
-- Governor Type Selection
-- Droop (nominal 4%)
[GRAPHIC OMITTED]
Interface displays can be in either English or Metric units.
Standard operator display language is English.
2.4.1.6 BACKUP INTERFACE
In the unusual event that the operator interface becomes
unavailable, a small backup interface is provided on the
▇▇▇▇ V cabinet door. It uses a liquid crystal display with
two (2) lines of forty (40) characters per line to display
key control parameters and alarms. The ▇▇▇▇ V accepts
operator commands from this backup interface.
2.4.1.7 PRINTER
The standard ▇▇▇▇ V operator interface printer is a 240 cps,
dot matrix type with these convenient features:
-- Alarm logging
-- Event logging
-- Historical trip display printing capability
-- User defined display printing capability
-- Periodic log display printing capability
-- CRT screen copy
Each alarm and event is logged with a high resolution time
tag. Contact inputs are logged to 1 millisecond. Separate
alarm queues are maintained for turbine/generator system
alarms and for ▇▇▇▇ V internal self-diagnostic alarms.
System alarms can be silenced, acknowledged and reset
locally or from a DCS via a two-way communication link, if
desired. Any intermittent alarms can be locked out with a
permanent lockout message residing in the alarm queue.
If a trip occurs, the historical trip display automatically
captures in memory all key control parameters and alarm
messages at the time of the trip and at several time
intervals preceding the trip. The operator can print the
historical trip display when required. A start signal
triggers the display to start collecting new data and all
previous data is deleted from the current log. Display logs
can be saved at any time to a memory buffer.
A user-defined display allows selection of any desired data
for viewing or printing. The periodic log allows a user to
define points to be collected and printed periodically to a
printer. The period of each list is defined in minutes, from
1 to 10,080 (one week).
2.4.1.8 DOCUMENTATION
Documentation for the ▇▇▇▇ V turbine control system consists
of two types: unit-specific drawings and instruction books.
A unique set of requisition-specific documentation is
supplied with each control system and three instruction
books are available for the specific needs of each user.
2.4.1.8.1 REQUISITION SPECIFIC DRAWINGS
-- I/O REPORT contains the unit-specific assignment of I/O
terminations in the ▇▇▇▇ V control panel. This report
also has I/O related information such as the signal
names.
-- CONTROL SEQUENCE PROGRAM PRINTOUT is a unit-specific
printout that shows a functional representation the Big
Blocks and sequencing of a particular requisition.
Software on the operator interface allows editing and
printing of this document from any location.
-- OUTLINE DRAWINGS provide an external view of the
control panel and primary operator interface. The
drawings furnish information needed for handling and
installing the equipment.
-- CASE LAYOUT DRAWING supplies an internal view of the
control panel. The primary purpose of this drawing is
to furnish information needed to route interconnect
cables.
-- CASE WIRING DRAWING defines the factory cabling
internal to the control panel case. The drawing's
primary purpose is to document the internal wiring for
maintenance use.
-- CORE DRAWINGS provide an isometric drawing of the core
depicting the cards and their respective locations
within the core. For each card, the physical location
and identification of removable parts, such as
connectors and hardware jumpers, are highlighted. The
core drawing is placed in a pocket on the inside of the
core door.

2.4.3 GENERATOR PROTECTION
2.4.3.1 GENERATOR PROTECTION PANEL
The current generator protection panel is the result of
years of research to best meet our customers needs and to
upgrade the generator protection panel to incorporate the
latest in digital technology. The heart of the generator
protection panel is the digital multifunction relay
integration with the ▇▇▇▇ V turbine control panel.
The standard generator protection panel incorporates this
features along with generator metering, Watt and Var
transducers for turbine control, and bus ground detection.
Pre-engineered protective modules such as generator step-up
transformer protection and auxiliary transformer protection
are not
included in the generator protection panels design. The
generator protective panel can also be customized to
incorporate protective and monitoring features as required.
A simple one-line diagram of the standard generator
protection panel is presented on the following page. This
one-line is for illustration purposes only. For job specific
details see the one-line diagram in the Equipment Drawings
chapter of this proposal.
[GRAPHIC OMITTED]
2.4.3.2 GENERATOR PROTECTION
The Digital Generator Protection is a compact, digital,
multiprocessor, space saving, multifunction protection
system. It's modular construction allows for easy
maintenance. The Digital Generator Protection module
provides a wide range of protection, monitoring, control and
recording functions for ac generators. It can be used on
generators driven by steam, gas and hydraulic turbines. Any
size of generator can be protected with the Digital
Generator Protection. A high degree of dependability and
security is achieved by extensive self diagnostic routines
and redundant power supplies.
The Digital Generator Protection provides the commonly used
protective functions in one package, including 100% stator
ground fault detection using 3rd harmonic voltage
monitoring. It has adaptive sampling frequency for better
protection during startup. The Digital Generator Protection
has eight configurable output relays, four trip and four
alarm relays.
The Digital Generator Protection can record the last 100
sequence of events, 120 cycles of oscillography fault
recording and the last 3 fault reports. These records and
fault reports require connection to a local (customer
supplied) PC for displaying of reports.
IRIG-B time synchronization capability is available within
the Digital Generator Protection Module. To take advantage
of this feature, the customer must supply all external
equipment.
A Man Machine Interface (MMI) with integral keypad, 16
character displays, and target LEDs allow easy local user
interface for entering settings, display present values,
view fault target information and access stored data. Some
of the present values that can be displayed are amps, volts,
Watts, Vars, power factor, negative sequence, third harmonic
level.
A front 9 pin RS232 serial ports allow both local and remote
computer access. Available options include, serial printer
port supplied on the rear, and Sequential trip such as the
33ST function for steam turbines. It can be specified to
operate with wye-wye or open-delta connected VTs and any
phase rotation.
2.4.3.2.1 GENERATOR LOCKOUT RELAY (86G-1)
Trips the generator breaker, the turbine, and the excitation
system. This lockout is normally tripped by either one of
the three functions 40, 87G or
59GN ( 64G1 ). The reasoning behind this is that if a loss
of excitation, or differential, or stator ground fault
occurs the structural integrity of the generator may have
been compromised and continued operation will potentially
lead to more devastating results. The turbine ▇▇▇▇ V logic
monitors this lockout.
2.4.3.2.2 BREAKER OR LOCKOUT TRIP COIL MONITOR (74)
Monitoring of trip coil circuit integrity is of sufficient
concern to warrant the installation of an auxiliary relay
and indicating lights for the lockout relays and generator
breaker. A high impedance relay 74 is placed in series with
the trip coil to be monitored. This relay drops out if
either the power source fails (i.e. a fuse blows) or circuit
integrity to the trip coil is interrupted. A visual
indication is also supplied via a white indication light
mounted on the front of the generator protection panel. The
contacts from the monitoring relay can go to either the
Turbine control panel or customer DCS for alarm
2.4.3.2.3 GENERATOR BREAKER CONTROL SWITCH WITH STATUS LIGHTS (52G/CS)
The generator breaker control is through the ▇▇▇▇ V [I]. The
52G/CS function provides a way to manually open the
generator breaker from the generator protection panel. This
breaker control switch is for TRIPPING ONLY, the breaker
can't be closed with it.
2.4.3.2.4 BREAKER DUAL COIL CROSS TRIPPING (94BG)
The standard panel has the capability to take full advantage
of redundant breaker trip coils when supplied on the
breaker. To take full advantage of the redundant breaker
coils (if supplied with the breaker) two separate dc sources
feed the trip coil circuits. The separation of sources is
normally via separate fusing. A high speed, low pickup
voltage auxiliary relay 94GB is placed in parallel with each
trip coil. Contacts from the relay in trip coil "A" circuit
are used to cross trip coil "B" and vice versa.
2.4.3.2.5 SYNCHRONIZING UNDERVOLTAGE RELAYS (27BS-1,2)
Undervoltage conditions can be present in a system due to
faults to ground, sudden energization of a considerable load
onto a loaded system, primary and backup regulator failure,
and when running up or coasting to a stop. The 27BS-1, and 2
are used with the ▇▇▇▇ V synchronizing scheme to provide
additional inputs to help determine whether the generator
can be synchronized
to a live or dead station bus. The ▇▇▇▇ V logic alarms when
undervoltage conditions are present after the breaker has
closed.
2.4.3.2.6 GENERATOR DIGITAL METER (DMM)
This single meter provides the following functions:
1. VM - Generator Volts: 1-2, 2-3, 3-1
2. AM - Generator Amps: Phases 1,2,3 and Neutral
3. MWATTS - Generator MegaWatts
4. MVAR - Generator MegaVARs
5. FM - Generator frequency
6. MVA - Generator MVA
7. PF - Generator Power Factor
8. MWH - Generator MegaWatt-Hours
9. MVAH - Generator MVA Hours
2.4.3.2.7 BUS GROUND FAULT (59BN)
This protection scheme is designed to protect the system
(station bus) from faults to ground. The synchronous
generator is connected through a breaker to a step-up
transformer. The low voltage side of this transformer is
usually connected in a delta configuration. If one phase of
the system should go to ground, virtually no fault current
would flow. However, voltage reference in the delta
connection will be fixed at the ground fault location
causing the voltage vectors to be shifted. One set of PT's
connected in a Wye - Broken Delta configuration, in
conjunction with an overvoltage 59BN relay, are used to
detect such a fault.
2.4.3.2.8 DC BLOWN FUSE PROTECTION (74)
Each lockout tripping circuit is fused independently in the
generator protection panel. If the fuse of a particular
tripping bus is blown, the associated protective relays
cannot trip the lockout relay. The intent of this function
is to alert the operator when the dc voltage to the tripping
bus is lost. This loss of dc can be a result of either a
blown fuse or incoming dc source failure/low level.
2.4.3.2.9 TRANSDUCERS (96GW1, GG1)
The main purpose of these transducers is to provide power
feedback to speed governing control in place of the
conventional fuel command feedback. The cases when this
function is required are:.
-- Constant Settable Droop (Gas Turbine of "Load
reference")
2.4.3.3 ▇▇▇▇ V INTEGRATION
In addition to the relaying mounted in the generator
protection panel, the ▇▇▇▇ V handles protection such as
generator temperature protection (49), synchronizing check
(25A), backup frequency and reverse power. Generator control
and monitoring is primarily accomplished via the ▇▇▇▇ V
operator interface. The ▇▇▇▇ V handles manual and
auto-synchronizing, speed raise/lower, voltage raise/lower,
and generator breaker control. The ▇▇▇▇ V operator interface
also displays frequency and voltage for the generator and
bus, breaker status, field current and voltage, along with
the status of permissive. For the gas turbines connected to
a generator breaker, the ▇▇▇▇ V auto/manual synchronizing
module will be capable of synchronizing across the generator
breaker and line breaker.
2.4.3.4 OPTIONAL PROTECTIVE FEATURES
The following additional protective features are
incorporated into a customized Generator Protective Panel.
This panel will be larger than the standard standard
generator panel.
2.4.3.4.1 SYSTEM BACKUP DISTANCE PROTECTION (21)
The distance relays are typically used instead of
overcurrent with voltage restraint when the lines leaving
the station bus have distance or pilot relay protection
schemes and the generator ties the station bus through a
step-up transformer.
This protection scheme is designed to protect the generator
from faults in the adjacent system which are not cleared by
the first line relays. It is used in lieu of 51V (system
phase fault over current relays with voltage restraint).
2.4.3.4.2 REVERSE/INADVERTENT ENERGIZATION PROTECTION (50RE/86RE)
This is also sometimes called: Accidental Energization, Back
Energization. Prior to the generator achieving rated speed,
the ▇▇▇▇ V arms/enables the trip
circuit ( using 14HS, i.e. 95% speed ) of the overcurrent
relay. A normally closed TMR contact is utilized in the ▇▇▇▇
V for maximum reliability both during normal operation and
during shutdowns ( i.e. ▇▇▇▇ V powered down ). When the
turbine is above 95% speed the ▇▇▇▇ V disarms the
overcurrent relay trip circuit, allowing the unit to be
synchronized.
An additional independent lockout 86RE is included to allow
the 86G fuses to be removed while the unit is shut down. The
trip contacts from the 86RE should trip customer upstream
breakers since the generator breaker trip coil may be
disabled (i.e. fuses removed during maintenance).
This protection scheme protects against inadvertent breaker
closure while the unit is at standstill, running up or down
in speed. One (1) three phase instantaneous overcurrent
relay 50RE is supervised by frequency/turbine speed
controlled outputs from the ▇▇▇▇ ▇.
2.4.3.4.3 VOLTAGE BALANCE PROTECTION (60)
The 60 relay is used in this protection scheme is designed
to prevent the misoperation of protective relays and/or
regulator in the event of PT signal loss. In the event a
potential transformer fuse is blown or the PT voltage is
lost for any reason, the excitation ac regulator and certain
relays may operate incorrectly. (See Note below.) The relay
is operational only when the generator breaker is closed.
Both set of contacts ("a" and "b") are monitored by the
turbine control panel. If the 60 relay indicates a blown
fuse, the turbine panel will alarm and appropriate relay's
trips are blocked.
NOTE: The EX2000 has its own internal logic to transfer from
auto regulator to manual regulator in the event of a loss of
its PT feedback signal. So the "b" contact from the 60 relay
would not be required in that application. Also the DGP
relay has a VTFF ( voltage transformer fuse failure )
function that may be used for transfer or blocking functions
if it is connected to the appropriate PT's. Finally, several
of the functions that the 60 relay is normally used for
(e.g. blocking the 40, 51V and 32 ) are functions that are
in the DGP. The DGP software automatically disables these
functions if it detects a loss of its PT input signal.
2.4.3.5 ELECTRICAL SYSTEM INTEGRATION STUDY
All necessary studies and calculations required to integrate
the generator panel into the electrical system, including
short circuit, load flow, installation and protective device
coordination studies are by Owner.
2.4.4 EX2000 DIGITAL EXCITATION SYSTEM
2.4.4.1 EX2000P DIGITAL, STATIC VOLTAGE REGULATOR FOR BUS FED
EXCITATION
The EX2000P is a digital, static, potential source
excitation system, utilizing the latest hardware and
software technology. To meet customer and operational
requirements, a full range of control and protection
functions are available for the product. A simplified
one-line diagram of the EX2000P with Hot Backup is shown
below.
[GRAPHIC OMITTED]
The EX2000P system comes equipped with a full-wave,
inverting, thyristor bridge which supplies excitation power
to the rotating field winding of the main AC generator. In
addition, all control and protective functions are
implemented in the system software. Digital technology
coupled allows the EX2000P to maintain 99.98% availability.
The EX2000P is comprised of four basic components: 1) Power
Conversion Module; 2) Digital Controller; 3) Excitation
Transformer; and 4) Communication (ARCNET) Interface. The
following briefly describe these basic components.
2.4.4.1.1 POWER CONVERSION MODULE
A three phase, full-wave, inverting thyristor bridge is the
standard power conversion module for EX2000P digital
exciters. The inverting bridge provides both positive and
negative field forcing voltage for optimum performance.
Negative forcing provides fast response for load rejection
and de-excitation. Software changes of the firing circuits
can be made to suppress negative forcing if it is not
required for the system application. The standard current
capability of the bridge is 6% above the calculated rated
full load field current of the generator.
The thyristor bridge assembly is forced air cooled. These
blower assemblies are all energized during normal operation.
Thermostats are used to monitor the power conversion module
temperature. An alarm is provided for a high temperature
level and a trip at an even higher temperature level.
2.4.4.1.2 EXCITATION TRANSFORMER
The excitation transformer is more commonly referred to as
the input Power Potential Transformer (PPT). It is in a
separate enclosure from the exciter. The power to the
transformer can be obtained a station auxiliary bus. The
purpose of this transformer is to step the voltage down to
the required level for the excitation system.
With the use of a regulator in the static exciter, it is not
necessary to specify transformer full capacity taps, above
and below normal, on the primary winding. The transformer
rating is chosen so that the transformer can deliver the
excitation required for the application at 105% rated
generator terminal voltage on a continuous basis
2.4.4.1.3 DIGITAL CONTROLLER
The Digital Controller consists of five printed wire boards
mounted on the front door of the Power Conversion Module.
The cards included are the Main
Processor Card, Microprocessor Application Card, Power
Supply and Instrumentation Card, Power Connect Card and LAN
Communications Card
2.4.4.1.4 COMMUNICATION (ARCNET) INTERFACE
For communications to the EX2000P, GE uses an ARCNET (local
area network) controller with modified ARCNET drivers. The
ARCNET controller adheres to standard ARCNET protocol
2.4.4.1.5 FEATURES AND FUNCTIONS
The exciter is enclosed in a NEMA-I stand alone enclosure
and contains the SCR power conversion module and regulator
with all standard control and protection functions, and
auxiliary functions such as de-excitation module, DC field
flashing module, and shaft voltage suppression circuit.
Standard features and functions and features included with
the EX2000P are listed below.
2.4.4.1.5.1 INTERFACE WITH THE GE SPEEDTRONIC ▇▇▇▇ V TURBINE CONTROL
SYSTEM
The connection between the EX2000 and ▇▇▇▇ V is accomplished
through a coaxial cable on the ARCNET LAN. Therefore, the
▇▇▇▇ V provides a digital window into the EX2000 through
which all pertinent variables can be monitored and
controlled (See Typical ▇▇▇▇ V display - EX2000 variables).
Any or all of the following functions can be provided:
-- Voltage matching
-- VAR/PF controller
-- Selection of automatic or manual regulator
-- Raise/lower of the active regulator set-point
-- Enter set-point command
-- Start/stop
-- Field volts, amps and transfer volts
-- Status and alarms
-- Field temperature

redundancy, the "Hot Backup" option is provided. This
feature utilizes a complete digital controller and rectifier
bridge as a backup to the primary controller and bridge.
During normal operation, the Hot Backup module receives the
same input as the primary module, but its output feeds a
small dummy load as opposed to the generator field.
If the protection module senses a condition that would
normally initiate a trip signal, it will force a transfer to
the Hot Backup module before the trip contact is necessary.
The transfer to Hot Backup is "on-the-fly" in the sense that
the transfer occurs with the generator on-line and does not
affect generator output

2.5.3 STATIC START SYSTEM
2.5.3.1 OPERATION
Using existing ac drive technology, GE will furnish a
Load-Commutating Inverter(LCI) adjustable frequency drive as
the starting means for the gas turbine.
The static starting system can accelerate the gas
turbine-generator without imposing high inrush currents with
resulting voltage disturbance on the A.C. station service
line. This system will provide variable frequency power
directly to the generator terminals, using the generator as
a synchronous motor to start the gas turbine. The generator
will be turning at approximately 4 RPM, via a low speed
turning gear, prior to starting. With signals from the
turbine control, the LCI will accelerate or decelerate the
generator to a self sustaining speed required for purge,
light-off , waterwash etc. Deceleration is a coast-down
function.
Starting excitation is provided by GE's EX2000 excitation
system
▇▇▇▇▇▇▇▇▇▇▇▇, ▇-▇▇▇▇▇ , ▇▇-▇▇▇▇▇ ▇▇▇▇▇▇ circuits are used
for the rectifier and inverter and are connected through a
dc link inductor. A transformer provides 3-phase power,
impedance for fault protection, and electrical isolation
from system disturbances to ground.
The drive system protective strategy is to provide a high
level of fault protection for the major equipment. The
protective relaying includes phase overcurrent, ground fault
and motor protection. The rectifier inverter will include
voltage surge protection and full fault suppression
capability for internal faults or malfunctions. A drive
system monitor and diagnostic fault indications continuously
monitor the condition and operation of the LCI.

satisfaction and the fulfillment of their objectives through
the products and services Power Generation has provided.
Integral to this are the following key elements:
- Customers are both internal and external.
- Quality measurements must be customer oriented.
- Complete understanding of customer requirements and
expectations is essential.
- Quality is to be achieved by designing and building
quality and reliability into our products and
services, optimizing our processes and minimizing or
eliminating inspections, waste and rework.
- Business processes and procedures instrumental in the
achievement of the Quality Policy are to be defined,
documented and controlled.
- Continuous process improvement efforts will focus
around process simplification, variation reduction and
cycle time compression, utilizing when able, "Best
Practices" as models and examples.
- Timely and effective corrective and preventive action
will be the key to the continuous improvement process.
- Management involvement plays a critical role in the
achievement of the quality objectives.
- The Power Generation Quality System will be based on the

It is the responsibility of the President and CEO, GE Power
Systems, and his management teams at all levels, to ensure
the understanding and implementation of this policy
throughout the business and to provide the necessary
processes, practices, procedures and resources necessary to
achieve that end.
11.1.2.3 MEASUREMENT
To ensure the success of the Quality Policy, appropriate and
meaningful measurements will be identified, developed and
reviewed at all levels and functions to ensure that
appropriate corrective and preventive action needs are
identified and addressed in a timely and effective manner.
The type and degree of such measurements will be of a nature
to evaluate the performance to the objectives implied in the
quality policy and consistent with the continuous
improvement philosophy of the business.
Such measurements may include, but not be limited to:
- Customer satisfaction measurements
- Internal and external failures
- Audit results
- Process and product quality trends
- Organizational performance data
- Product performance data
- Statistical analysis techniques
- Related cost data
11.1.2.4 REFERENCES
This policy is intended to support the objectives
established in Company Policy 20.1 "Company Wide Quality"
and Company Policy 20.11 "Customer Satisfaction".
11.1.2.5 REVIEW
The Quality Policy will be reviewed annually by Executive
Management in order to assure its continued applicability
and objectives.
11.1.3 ISO 9000 CERTIFICATION
The desire for customer satisfaction drives world class
quality. Customers throughout the world are not only
demanding a high level of quality, they are requiring this
quality be assured through the application of a
comprehensive quality program. The ISO 9000 program and
certification provide customers with a globally recognized
Quality Management system.
In order to be more responsive to our customer's needs GE
took this customer requirement and made it a top priority.
Our Sales, Engineering, Sourcing and Manufacturing functions
worked diligently to accomplish ISO certification. GE takes
great pride and pleasure in the fact that we were the first
power generation supplier to obtain broad scope ISO
certification. Lloyd's Register Quality Assurance has
assessed and approved GE's quality management system
standards of ISO 9001:1994, EN ISO 9001:1994 and ANSI/ASQC
Q9001-1994.
GE has focused on this quality issue, with customer
satisfaction being the top priority. The driving force
behind our total quality system is to achieve total customer
satisfaction by minimizing variances and completing the
product or services correct the first time. We established
our quality measurements and targets based on the most
demanding of our customers' perspective. To satisfy this
high level of demand, we focused on our "process" quality,
not just the end-products and services. To achieve this we
have directly involved our employees, our customers and
suppliers in these process improvements.
What really counts is our customers' perception of how well
we meet their quality requirements and goals. Therefore, our
quality measurements and procedures are being constantly
monitored and evaluated against both our own high standards
and our customers' needs.
11.1.4 TOTAL QUALITY PLAN
GEPG has an integrated total quality plan which addresses
all processes, involves all employees and is driven by top
management leadership. The principles of total quality are
based on achieving total customer satisfaction by minimizing
variances and doing the right thing the first time. These
principles are:
- Total commitment to quality at every salaried and hourly
level
- Assure understanding of customer requirements and
expectations
- Directly involve our customers and suppliers in process
improvements
- Assign ownership for process design and control to
empowered Workout/Continuous Improvement teams
- Focus on "process" quality - not just end-products and
services
- Set our quality measurements/targets from the most
demanding customer's perspective
- Define the key measures needed to assess variances in
process performance
- Apply Continuous Improvement methods to reduce variances
and cycle times to progressively improve overall
performance
- Train employees and maintain a cadre of leaders
- Implement tracking and reporting systems to monitor
progress and results
- Monitor all elements of Cost Of Quality (COQ), including
prevention, appraisal, and internal and external failure,
plus the impact of "lost opportunities" on net operating
income
- Identify and progressively eliminate the source of all
avoidable COQ
- Identify, recognize, and reward exceptional individual
and team performance
GEPG recognizes that ISO 9001 certification covers the basic
fundamentals of a quality system. To attain total quality,
GEPG has created a comprehensive Quality Manual which meets
the requirements of the most demanding customer and sets the
total quality guidelines.

new unit. The system enables GE's turbomachinery experts
located at the M&D Center in Schenectady, NY to remotely
monitor trends and detect anomalies that may lead to more
serious problems if left uncorrected.
The system requires installation of a non-intrusive,
proactive GE proprietary computer called the On Site Monitor
(OSM) at the customer site to receive and store data from
sensors in the unit. The M&D Center, which operates 24 hours
per day, seven days a week, periodically accesses the OSM
via a phone modem. At the end of the warranty, the OSM may
be removed from the customer site.

11.5.1 SUPPLIER QUALITY SYSTEM
GE Power Systems utilizes the following three step process
for selecting and controlling the quality of the products
received from our suppliers:
- Supplier Approval--An approved supplier is one that
has been authorized by functional representatives to
receive a GE Power Generation Purchase Order.
Additional suppliers are selected for potential
approval on an on-going basis to maintain high
quality, cost effective suppliers.
- Supplier Qualification--Product specific reviews,
inspections and qualifications are performed once a
purchase order has been placed to assure the supplier
complies with the customer requirements. A qualified
supplier is one that has proven its ability to
manufacture a component to satisfactorily meet all GE
requirements.
- Supplier Surveillance--Inspections and quality audits
are performed where required to assure conformance to
customer requirements.
11.5.2 SUPPLIER QUALITY SYSTEM REVIEW
GE Sourcing (purchasing) personnel or a GE representative
will arrange for and accompany where necessary the
customer's representative on quality-oriented visits to
subsuppliers. Emphasis is placed on equipment to be shipped
direct to the customer site (MSD equipment). The customer's
representative may review the subsupplier's quality program,
the GE quality plan for the subject equipment and the status
and condition of the equipment designated for their unit.
This visit should be coordinated with specific supplier
production cycle events or tests as applicable.
--------------------------------------------------------------------------------
11.6 STANDARDS AND PROCEDURES
11.6.1 GENERAL
GE has traditionally designed and manufactured its products
in accordance with GE standards, specifications and
procedures which are based on U.S. National Codes and
Standards applicable to the product. Depending on product
needs, the GE standards may fully meet or exceed the
corresponding National Code (ASME, NEC, QWS), or deal with
state-of-the-art materials, or govern a new proprietary
process, or address a special foreign code requirement or
meet GE design requirements.
The customer or his representative may review and discuss
the standards at the manufacturing facilities but copies
will not be provided and contents will not be altered.
GE specifications, standards, and procedures are also
applied to all purchased materials for the GE supplied
equipment.
11.6.2 NON-DESTRUCTIVE TESTING (NDT)
The non-destructive testing practices are based on ASTM
standards and ASNT recommended practices as deemed
appropriate for the manufacture of the equipment. NDT
personnel training is guided by SNT-TC-1A and the necessary
process specifications are in place to direct NDT activities
including:
- Radiographic (X-Ray)
- Liquid Penetrant (Red Dye)
- Fluorescent Penetrant (i.e. Zyglo)
- Ultrasonic
- Eddy Current
- Magnetic Particle
- Bore Etch and Spin
- Hydrostatic Testing
- Kerosene and ▇▇▇▇▇▇▇
- Red and Blue Surface Contact
11.6.3 RIGHTS OF APPROVAL AND ACCEPTANCE
GE reserves all rights of acceptance/rejection for
components or characteristics except where specifically
defined in the GE/Customer contract documentation.
Customer reviews or observations of factory tests and
inspections do not constitute a waiver of requirements to
meet the specified operating conditions, nor does customer
inspection relieve GE of its responsibilities.
11.6.4 DRAWINGS AND RECORDS
Drawings and records are available for review and discussion
on a specific case basis at the manufacturing facility.
Copies will not be provided except for normal purchaser
drawings and where specifically required in the contract.
--------------------------------------------------------------------------------
11.7 CUSTOMER REVIEW OF GE DOCUMENTATION
A customer may review whatever quality control plans,
procedures, drawings or records are necessary for
operations/tests/inspections performed on his parts. (Under
certain conditions when his parts may not be available,
`typical' documentation, may be reviewed to demonstrate
examples.) Due to the fact that such documentation usually
contains information considered proprietary, copies are not
provided.
All documentation reviews will be conducted with an
authorized representative, such as the area Quality and
Process Engineer. This is necessary as such documentation is
usually of a "working" nature and will need interpretation
by a knowledgeable individual.
Since the review of documentation and data will usually
involve in-process product and activities, certain types of
documentation may not be made available for customer review
until after full resolution and/or implementation of related
issues.
Advance submittals of specifications, procedures and
manufacturing quality plans are not provided.
--------------------------------------------------------------------------------
11.8 CUSTOMER OBSERVATION POINTS
The customer, by previous arrangements, can be notified in
advance of significant events in the manufacturing cycle for
his major hardware. The normal practice is to provide the
customer with a monthly "milestone" schedule of key
activities for each of the customer's units.
If specific observation points have been contracted, advance
notification (usually 5 days) of observation points will be
provided with confirmation of 24 - 48 hours. Production
work, testing and equipment delivery will not be delayed to
accommodate the inspector.
Supplied equipment and parts are manufactured under a
production and inventory control system. Many parts are
produced for "inventory" and are not assigned to a specific
customer until time of shipment. Thus, except for certain
large components and major serialized parts, it may not be
possible to provide an observation point on the actual parts
a customer will receive. In such cases, GE recommends that a
customer observe the test or inspection on similar parts to
assure that the procedures and processes are being followed
that will assure a quality part.
The following tests and inspections are performed in the
manufacturing facilities and, are optional observation
points. This list should not be taken to mean that any one
such test will be performed on a particular part. These
points have been developed by GE based upon considerable
past experience of what some of our customers have wanted to
observe.
11.8.1 GAS TURBINE TESTS AND INSPECTIONS
11.8.1.1 ROTOR FINAL BALANCE (OBSERVE) - OPTIONAL
THE CUSTOMER REPRESENTATIVE IS INVITED TO OBSERVE THE NORMAL
PRODUCTION OPERATION OF FINAL ROTOR BALANCE AT THE
APPROPRIATE POINT DURING THE MANUFACTURING CYCLE OF THE
CUSTOMER'S UNIT. WHILE GE CAN NOT GUARANTEE THE ROTOR WILL
ACTUALLY BE USED IN THE CUSTOMER'S UNIT DUE TO SHIPMENT
PRIORITIES, GE WILL MAKE EVERY ATTEMPT TO HAVE THE
DESIGNATED ROTOR BE BALANCED. THE COMPLETED ROTOR IS SET UP
IN THE BALANCE MACHINE AND STABILIZED. UNBALANCE READINGS
ARE TAKEN IN TWO PLANES AT LOW SPEED (300 TO 500 RPM) AND
BALANCE CORRECTION IS APPLIED TO ONE OR MORE PLANES BY
WEIGHT ADDITION OR REMOVAL. FINAL BALANCE READINGS AND
MATHEMATICAL CHECKS ARE PERFORMED TO ASSURE AN ACCEPTABLE
ROTOR.
Final rotor balance is a single operation on the entire unit
for MS6001B, MS6001F, MS7001F, MS9001F gas turbine models
(two bearing designs). The MS7001E and MS9001E models,
(three bearing designs), have separate balance operations
for the compressor section rotor and the turbine section
rotor. Manufacturing methods and priorities are such that
the customer should plan on separate visits where multiple
balancing operations are to be observed.
Since GT rotors are considered rigid and are made up of
individually balanced, geometrically-controlled components,
the low speed balancing operation adequately ensures low
vibration levels in the operation unit.
11.8.1.2 TURBINE FACTORY FINAL TEST (OBSERVE) - OPTIONAL
Factory no-load testing is the principal method of assuring
that the gas turbine unit is operable and that the
aero-thermal performance is acceptable as compared to
factory testing on similar models. Factory testing of gas
turbines will be performed on an audit basis as determined
by GE. When a customer's specific machine is scheduled for
testing, the customer or his representative(s) may be
invited to directly observe operation of his gas turbine
during its normal final fire testing.
11.8.1.3 UNIT READY FOR SHIPMENT (OBSERVE) - OPTIONAL
Consisting of up to two (2) distinct inspection points
depending on the machine and the customer objectives, this
option starts with a walk around inspection of the unit in
the final stages of preparation for shipment. This
inspection is after final painting but before the bolting of
▇▇▇▇▇▇ strips which secure the side panels and prevent
internal access for machines with on-base lagging. During
this inspection the customer may review overall workmanship,
completeness of assembly, adequacy of prime painting,
application of flange blanking plates, preservation
techniques and general shipping practices.
Next the customer may desire to see his unit on
the rail car ready for shipment. The unit is
fully enclosed, if an on-base lagging design, is
secured to the car and appropriately marked. It
is then shipped by rail, either to location or to
port.
11.8.2 GENERATOR TEST AND INSPECTIONS
11.8.2.1 GENERATOR STATOR
11.8.2.1.1 FINAL ELECTRICAL TEST (OBSERVE)
The typically two (2) to four (4) hour inspection includes
the following:
- GENERAL VISUAL INSPECTION OF THE FULLY ASSEMBLED STATOR
- WINDING RESISTANCE MEASUREMENT--The dc resistance of each
phase is measured with a low resistance ohm meter along
with the winding temperature.
- INSULATION RESISTANCE MEASUREMENT--Prior to the final
winding high potential test, the insulation resistance
over a ten minute period is measured with a 500 volt dc
insulation tester.
- HIGH-POTENTIAL TEST--The windings of the armature are
tested by grounding two phases and applying a 60 Hz
voltage whose RMS value is twice the machine's rated
voltage plus 1000 volts. This test is repeated for each
phase. This test is done per GE standard which meets or
exceeds IEEE 115 and ANSI C50.10.
11.8.2.2 GENERATOR FIELD
11.8.2.2.1 OVERSPEED AND BALANCE (OBSERVE)
OVERSPEED TEST--The overspeed test is intended to expose
the components of the field assembly to forces higher than
normal and demonstrate the ability of the field assembly to
withstand such forces. The field is set up in the high speed
balance facility, it is held for three minutes at a speed
20% above the rated speed of the unit.
HIGH SPEED BALANCE--The generator field will undergo a
high speed balance. The primary objective of precision
balancing is to reduce the residual unbalance of the
field to the lowest possible level. The approach used in
balancing fields is called modal balancing. Each mode of
vibration, or critical speed, is balanced in turn,
starting with the lowest speed, on first mode. The
process proceeds to each critical in turn from the first
to the highest critical within the operating speed range.
After all criticals are balanced to a small residual
vibration level, balance at rated speed is evaluated.
11.8.2.2.2 FINAL ELECTRICAL TEST (OBSERVE)
- WINDING RESISTANCE MEASUREMENT--The dc resistance of each
phase is measured with a low resistance bridge. The
winding temperature is also measured.
- INSULATION RESISTANCE MEASUREMENT--Prior to the final
winding high potential test, the insulation resistance
over a ten minute period is measured with a 500 volt dc
insulation tester.
- High-Potential Test--The windings of the field are tested
by applying 10 times the rated field voltage but not less
than 1500 volts ac between the field winding and ground
for field voltages of 500 volts or less. For fields
rated greater than 500 volts, the test voltage is twice
the rated voltage plus 4000 volts ac. This test is done
per GE standard which meets or exceeds IEEE 115 and
ANSI C50.10.
11.8.3 CONTROL PANEL FACTORY TEST (OBSERVE)
The gas turbine control panels are manufactured at GE's
Salem, Virginia plant. Components and modules such as
electronic cards and page assemblies undergo extensive
inspection and automated computer testing before they arrive
at final assembly. All modules with back plane wiring are
automatically machine wired and computer checked.
After the components and modules are assembled in their
parent panel, the equipment is made ready for final test and
inspection. The major portions of this procedure include
testing and checking of the following:
- All final assembly wiring
- Power distribution and supply systems
- Input/output systems
- Automated (PC based) hardware loop back-checks
- System operation using test software
- Customized requisition software checked in a "Software
Test Bed" facility using permanent electronic modules for
test
- For a control panel installed in a control compartment,
interfaces between generator control panel and other
compartment systems.

STARTUP AND OPERATION DOCUMENTS
Documentation associated with the checkout, initial startup
and routine operation of the Gas Turbine Generator Packaged
Power Plant include the following:
- Consolidated Service Manuals; available at time of unit
shipment
- Turbine Control Specification; available at time of unit
shipment
- Elementary Diagrams; available at time of unit shipment
- Startup Report; available after initial operation of
the unit
In addition, previously supplied functional drawings such as
the one line, schematic piping device summary and elementary
diagrams are heavily utilized during the functional checkout
and initial startup operations.
CONSOLIDATED SERVICE MANUALS
The Consolidated Service Manuals are comprised of: Instruction
Book, Inspection & Maintenance Manual and Spare and Renewal
Parts Book. Twelve (12) copies are provided.
The Instruction Book portion of the Consolidated Service
Manuals contains site specific information on turbine
generator operation. Normal operating sequences are described,
together with normal running inspections for all supplied
equipment and systems. Trouble-shooting and diagnostic
recommendations are also included. Special notes, and
cautionary and warning statements are included and highlighted
throughout the instruction book to enable easy recognition of
special procedures and techniques which must be followed to
ensure correctness and safety for equipment and personnel.
Operating information is also included for all components and
systems that are standardized in their design.
The Inspection and Maintenance Manual provides information for
inspection and maintenance of the gas turbine, its accessories
and auxiliary systems over the life of the equipment.
Recommended procedures for scheduling inspections and planning
maintenance outages, including recommended spares, tools and
equipment are provided. Standard practices for
disassembly, component inspection and reassembly are described
in detail. Copies of the necessary reporting forms are also
provided.
The Spare and Renewal Parts Book includes all necessary gas
turbine accessory and auxiliary system drawings to allow the
ordering of replacement and expendable materials, parts,
components, and assemblies for all routine inspection and
maintenance activities. It is organized along the same lines
as the model list, or master drawing index, used to
manufacture the gas turbine in the factory, and is specific to
the site.
TURBINE CONTROL SPECIFICATION
The turbine control specification provides all recommended
turbine control panel settings, control system calibration
procedures and turbine operating sequences. It is a site
specific document, and together with the device summary and
gas turbine and generator elementary, provides information on
all field settable control and protective equipment.
ELEMENTARY DIAGRAMS
Elementary diagrams are provided for the gas turbine and
generator controls, including the excitation system. The
turbine control elementary diagram is primarily functional,
and although some hardware representation is included where
appropriate, it concentrates on a pictorial representation of
the turbine and auxiliary system sequencing and control and
protection algorithms implemented in the panel software. The
turbine control panel is also supported for checkout purposes
by a hardware connection diagram that depicts all internal
hardware connections.
The generator and power system elementary diagram is also
functional, however, since control, protection and sequencing
are accomplished with hardware elements, it is more
representative of the actual system hardware configuration.
The same is also true of the motor control centers for all
electrically powered auxiliaries.
STARTUP REPORT
The startup report is prepared by Seller's field startup
engineer after completion of the initial operation of the
unit. It provides an indication of the initial settings and
startup control characteristics for the gas turbine, generator
and all auxiliary systems. It is useful for anticipating
trouble and performing diagnostic work at least through the
first inspection period, and in many cases, over the life of
the installation.
