Common use of Installation and Permitting Clause in Contracts

Installation and Permitting. 4.1 Without limiting the provisions of paragraph 22, the Owner and the System must comply with all applicable National Electric Code (NEC), UL and IEEE requirements, including, but not limited to: UL 1741-Standard for Static Inverters and Charge Controllers for Use with Photovoltaic Systems. IEEE Standard 1547 (2003): Standard for Interconnecting Distributed Resources with Electric Power Systems. [NOTE: UL 1741 will soon be incorporated into IEEE 1547]. Other organizations, such as the Canadian Standards Association (CSA), test to UL 1741. If the inverter is tested by an organization other than Underwriters Laboratories, the test data must be submitted to BLW. The Owner at the Owner’s expense must: 1) obtain all necessary electrical permits for installation of the System and 2) obtain and maintain any government authorizations or permits required for the operation of the System. The Owner must reimburse BLW for any and all losses, damages, claims, penalties, or liability BLW incurs as a result of Owner’s failure to obtain or to maintain any governmental authorizations and permits required for construction and operation of the Owner’s System. 4.2 The Owner or its contractor must construct the System as specified in the attached Exhibit A. 4.3 A manual, lockable, load-break disconnect switch that provides a clear indication of the switch position must be available with the System at or near the Owner’s main point of service from BLW’s electric system to provide a point of electrical separation between the Owner’s System and BLW’s electric system. BLW will approve the location of the disconnect switch. The disconnect switch must be easily visible, mounted separately from the metering equipment, readily accessible to BLW personnel at all times, and capable of being locked in the open position with BLW’s lock. BLW may open the disconnect switch thereby isolating the Owner’s System from the BLW electric system for any reason that BLW deems necessary including, but not limited to, maintenance or emergency work, the System adversely affecting other customers of BLW, failure of the System to comply with codes/regulations, the System creating hazardous or unsafe conditions, the Owner’s failure to pay utility bills when due, and failure to comply with the UL Standards in Section 4.1 above.

Installation and Permitting. 4.1 Without limiting the provisions of paragraph 22, the Owner The Customer and the System must comply with with: 1) all applicable National Electric Code (NEC), UL and IEEE ) requirements, including, but not limited to: UL 1741-Standard for Static Inverters to NEC Articles 690 and Charge Controllers for Use with Photovoltaic Systems705; 2) all building codes; and 3) all applicable Underwriters Laboratories (UL) requirements and standards. IEEE Standard 1547 (2003): Standard for Interconnecting Distributed Resources with Electric Power Systems. [NOTE: UL 1741 will soon be incorporated into IEEE 1547]. Other organizations, such as the Canadian Standards Association (CSA), test to UL 1741. If the inverter is tested by an organization other than Underwriters LaboratoriesAt its sole expense, the test data must be submitted to BLW. The Owner at the Owner’s expense Customer must: 1) obtain all necessary electrical permits permit(s) for the installation of the System System, and 2) obtain and maintain any government governmental authorizations or permits required for the operation of the System. The Owner Customer must reimburse BLW Springs Utilities for any and all losses, damages, claims, penalties, or liability BLW Springs Utilities incurs as a result of Ownerthe Customer’s failure to obtain or to maintain any governmental authorizations and permits required for construction and operation of the OwnerCustomer’s System. 4.2 The Owner Customer or its contractor must construct the System as specified in the attached Exhibit A. 4.3 A manual, lockable, load-break disconnect switch that provides a clear indication of the switch position must be available with the System at or near the OwnerCustomer’s main point of service from BLW’s Springs Utilities’ electric system to provide a point of electrical separation between the OwnerCustomer’s System and BLW’s Springs Utilities’ electric system. BLW Springs Utilities will coordinate and approve the location of the disconnect switch. The disconnect switch must be easily visible, mounted separately from the metering equipment, readily accessible to BLW Springs Utilities’ personnel at all times, and capable of being locked in the open position with BLW’s a Springs Utilities’ lock. BLW Springs Utilities may open the disconnect switch thereby isolating the OwnerCustomer’s System from the BLW Springs Utilities’ electric system for any reason that BLW Springs Utilities deems necessary (including, but not limited to, maintenance or emergency work, the System adversely affecting other customers of BLWSprings Utilities, failure of the System to comply with codes/regulations, the System creating hazardous or unsafe conditions, the OwnerCustomer’s failure to pay utility bills when due, and failure to comply with UL Standard 1741 (Standard for Static Inverters and Charge Controllers for Use in Photovoltaic Systems), or failure to comply with UL Standard 1703 (Standard for Safety: Flat-Plate Photovoltaic Modules and Panels). 4.4 Springs Utilities requires a second (recording) metering point to record energy generated by the UL Customer’s System. At its sole expense, the Customer must furnish and install as part of the System a meter socket (base) in accordance with Springs Utilities’ Electric Line & Extension Service Standards. Springs Utilities will furnish the meter for insertion into that meter socket (base) at no charge to the Customer. This second meter will have no affect on the Customer’s utility ▇▇▇▇ and is for informational purposes. 4.5 The System must comply with all Institute of Electrical and Electronics Engineers (IEEE) Standards 929-2000 (Recommended Practice for Utility Interface of Photovoltaic Systems), as of the Effective Date, for parallel operation with Springs Utilities. The purpose of these IEEE Standards is to minimize custom engineering of many aspects of the interconnection. These standards allow installation in Section 4.1 above.a manner that will allow the System to perform as expected and to be installed at a reasonable cost while not compromising safety or operational issues. All power quality parameters (that is, voltage, flicker, frequency, distortion) are specified at the point of common coupling (PCC) unless otherwise stated. In particular, the following requirements must be met: 4.5.1 Voltage – the System must be capable of operating within normal voltage operating limits of 106-132 volts (88-110% nominal 120V). This range results in trip points at 105 V and 133 V. Response to abnormal voltages should be as follows: Voltage (at PCC) Maximum trip time V<50% 6-cycles 50% < V < 88% 120-cycles 88% < V < 110% normal operation 110% < V < 137% 120-cycles 137% < V 2-cycles
