BSC Bulletin 327 - BMRS calculations on hold due to issue loading BOALF data

What is happening?

Balancing Mechanism Reporting Service (BMRS) Settlement Calculations have been put on hold from Settlement Period 19 today, 8 February, to prevent publication of incorrect System Prices data.

ELEXON is investigating an issue where BMRS cannot load and publish Bid Offer Acceptance Level Flag (BOALF) data.  

How will I be impacted?

The BOALF data is used in the BMRS Settlement Calculations and due to this issue, the BOALF data cannot be included in the Settlement Calculations. We have therefore suspended the BMRS Settlement Calculations. This has also created a backlog of Maximum Import Limit/Maximum Export Limit (MIL/MEL) data; therefore BOALF and MIL/MEL data are not currently published on the BMRS website, APIs, Data Push Service and TIBCO.

All other data on the BMRS is being published as expected.

Do I need to take any further action?
