Formal title: Removal of Emergency Instructions taken for System reasons from Imbalance Price

Summary

On 19 May 2004 the System Operator (SO) issued an Emergency Instruction to Damhead Creek Power Station to stop them exporting onto Transmission System. In accordance with the Grid Code BC 2.9.2.3 this instruction should have been treated as a Bid Offer Acceptance (BOA). Section Q 5.1.3 then provides the link between the Grid Code and the BSC by outlining a list of communications that will be classified as Acceptances. British Gas Trading (BGT), in raising this Modification proposal, is not proposing to change the process for issuing Emergency Instructions, merely how they are included in the calculation of imbalance prices. The SO currently has the ability to tag forward contracts which includes Energy Related Products, PGB Transactions and System to System services as System or Energy related. This is in accordance with the Balancing Services Adjustment data Methodology Statement (BSAD).
