Summary
The Balancing Settlement Code (BSC) calculates BOA volume based on the Final Physical Notification (FPN) submitted by the Party. In the majority of settlement periods it is appropriate to calculate the BOA volume based upon the FPN. However British Gas Trading (BGT) has identified an anomaly in the calculation of the BOA volume in specific circumstances. This anomaly occurs when a Party re-declares its Maximum Export Limit (MEL) below its FPN after Gate Closure and the System Operator (SO) then accepts a Bid from the Balancing Mechanism Unit (BMU). BGT believe the anomaly identified has a direct impact on the calculation of BOA volume and therefore Party’s credited volume.
Progression
The Authority rejected the Proposed Modification on 28 January 2005.
