Formal title: BSCP18 Operational Review: Additional flag in Transmission Company’s BOAL file to indicate an amended Bid-Offer Acceptance

Current Status

CPC Consultation
Committee Decision
Awaiting Implementation


Elexon raised CP1286 to introduce a process to automate Bid-Offer Acceptance Level (BOAL) data corrections. Currently the BSC Systems will reject any automatically sent BOAL data corrections. Therefore BOAL data corrections are entered manually. This is time consuming and introduces the risk of human error. A new field, the ‘Amended Acceptance Flag’, which identifies a BOAL data correction, would be added to the BOAL file. The BSC Systems would be amended so that they automatically accepted a BOAL data correction if the Amended Acceptance Flag was set to ‘True’. The change would: increase the efficiency of the process for Elexon and the BSC Agent; and increase the transparency of the process to BSC Parties as data would be available on the BMRS (including TIBCO) earlier than it appears in the SAA Settlement Reports.


CP1286 was raised on 03 April 2009. CP1286 was issued for Industry Impact Assessment as part of CPC00660. CP1286 was presented to the ISG for decision on progression. The ISG approved CP1286and it was implemented as part of the November 2009 Release.
