Common use of Operational Balancing Account Clause in Contracts

Operational Balancing Account. 4.6.1. The Parties undertake to put effort so as to maintain TBP as close as possible to zero, in order to ensure that the LR specified in paragraph 4.6.2 is not violated. 4.6.2. The LR is specified by its lower limit value (LRlow), which is set to -8,500,000 kWh and its upper limit value (LRup) which is set to 8,500,000 kWh. The lower and / or upper value of the LR may be changed upon mutual agreement of DESFA and BULGARTRANSGAZ, in case of justified operational needs, including but not limited to: (a) Exceptional events (b) Unplanned maintenance works (c) Scheduled flow below the BMS Sidirokastron minimum measurement and / or flow control limits. (d) Increase or decrease of the IP’s technical capacity. Upon written request issued by one of the Parties, the Parties may agree to expand the limits of the LR, prior to the execution of the indicative and / or the final allocation of the Natural Gas quantities for a Day D or for a certain number of Days. 4.6.3. In order to carry out the indicative allocation of the Natural Gas quantities to each Pair of Network Users, for a Day D, the Parties shall check whether the LR, applicable for that Day D, is violated. (i) If for the Day D ,, −1 + ∑ or ,, −1 + ∑ − ∑ ,, − ∑ ,, − > − < the Parties shall carry out the indicative allocation of Natural Gas quantities in accordance with the provisions of paragraph 4.5.4. (ii) If for the Day D ,, ≤ −1 + ∑ − ∑ ,, − ≤ the Parties shall carry out the indicative allocation of Natural Gas quantities in accordance with the provisions of paragraph 4.5.2. 4.6.4. In order to carry out the final allocation of the Natural Gas quantities to each Pair of Network Users, for each Day D of the Month M, the Parties shall check, based on validated measurements, whether the LR, applicable for that Day D, is violated. (i) If for the Day D ,, −1 + ∑ or ,, −1 + ∑ − ∑ ,, − ∑ ,, − > − < the Parties shall carry out the final allocation of Natural Gas quantities in accordance with the provisions of paragraph 4.5.4. (ii) If for the Day D ,, ≤ −1 + ∑ − ∑ ,, − ≤ the Parties shall carry out the final allocation of Natural Gas quantities in accordance with the provisions of paragraph 4.5.2. 4.6.5. Prior to the termination of the Interconnection Agreement, the Parties shall endeavour to settle in kind the TBP by adjusting the flow through the IP appropriately. If the TBP, that will be calculated at the last Day of implementation of the Interconnection Agreement is different than zero (0), then the Parties shall settle the TBP financially, within 30 days upon the Day of termination of the Interconnection Agreement, using as TBP unit price the arithmetic average of the marginal buy and marginal sell unit prices of balancing gas, without adjustments (if such adjustments are applicable), valid for the natural gas market of the creditor, for the Day of termination of the Interconnection Agreement. In case there are no applicable marginal prices of the balancing gas valid for natural gas market of the creditor, then the applicable daily price of balancing gas without adjustments will be used as a TBP unit price. The daily price of the balancing gas will be published on the internet site of the creditor. The balancing gas unit price, published and calculated by the creditor shall be in accordance with the methodology approved by the competent National Regulatory Authority. 4.6.6. DESFA shall issue and forward to BULGARTRANSGAZ the monthly OBA protocol until 15:00 of the third calendar day of the Month immediately succeeding the Month M The ΟΒΑ Protocol shall be in accordance with the standard form of Annex 9 of the Interconnection Agreement. 4.6.7. DESFA shall send daily to BULGARTRANSGAZ an Account Situation Document (ACCSIT) notification containing the TBP, in accordance with the Edig@s-XML format, not later than 11:00 local time on the Day D+1. The excel document-based data exchange method shall be used temporarily by the Parties as a back-up solution in case of failure of the above mentioned data exchange method.
