What is happening?

Further to ELEXON Circular EL03077 , the BSC Central Systems outage which was planned today between 18:57 (GMT) and 00:45 (GMT) has now been completed successfully.

How will I be affected?

All the systems are now running and we have started the Settlement Calculations on Balancing Mechanism Reporting Mechanism Service (BMRS) and the scheduled reports for Energy Contract Volume Aggregation Agent (ECVAA) and Settlement Administration Agent (SAA). We expect the BMRS data to be fully recovered by 01:45 (GMT) today.

The majority of the SAA Settlement Reports (SAA-I014) will be delivered today as planned with the exception of the RF report which has been scheduled to run tomorrow, 12 December 2019 as shown below.
