Now Completed: Planned brief downtime required for essential maintenance of BSC Central Systems 

What is happening?
There will be a brief period of planned downtime on the BSC Central Systems applications from 13:10 to 13:50 (BST) on Wednesday 18 July. This downtime is required to perform essential maintenance of the BSC Central Systems applications including the Balancing Mechanism Reporting Service (BMRS), Energy Contract Volume Aggregation Agent (ECVAA), Settlement Administration Agent (SAA), Central Data Collection Agent (CDCA) and Central Registration Agent (CRA).

How will I be impacted?
During the downtime, data received from National Grid will not be updated on the BMRS website. Additionally, users of the BMRS APIs, TIBCO and Data Push Service will not receive the latest data set.

The ECVAA application and web service will be impacted by the downtime and in accordance with the procedures, common submission of ECVNs and MVRNs to ECVAA will not be processed and the ECVAA Credit Check will also be suspended for the duration of the downtime. Following completion of the downtime, the ECVAA Credit Check will be re-enabled and submission of ECVNs and MVRNs will be processed as normal.

What do I need to do?
You will need to arrange for your Party Agents to submit before 13:10 (BST) on 18 July 2018, all contract notifications for Settlement Periods 28 and 29 for 18 July 2018.

Please submit all contract notifications for the affected Settlement Periods as early as possible to reduce the risk of them missing Submission Deadline. 

Will I receive ECVAA reports as normal?
Yes, all scheduled ECVAA reports are not impacted by the planned downtime.

Will the contents of any of the reports I receive be different?
Yes, the ECVAA Notification Report (ECVAA-I014) for 18 July 2018 may not contain credit limit and indebtedness information for the affected Settlement Periods.  Indebtedness data will be accurately reflected for Settlement Periods for which credit checking first runs in normal mode.

Will there be any further communications about this downtime?
Yes, we will keep the ELEXON Portal updated and will publish a further update on 18 July 2018 when the downtime is finished.
