IT notices: Maintenance to BSC Central Systems 13 May 2020

There will be period of planned downtime on the BSC Central Systems from 19:15 to 20:45 (BST) on Wednesday 13 May 2020.

This downtime is required to perform essential maintenance of the BSC Central Systems which will result in intermittent service on the Balancing Mechanism Reporting Service (BMRS) and Energy Contract Volume Aggregation Agent (ECVAA).

How will I be impacted?


During the downtime, the BMRS may experience delays in publishing the latest data set received from National Grid ESO and this will impact the data on the BMRS Website, APIs, TIBCO and Data Push Service.


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 Notification Agents to submit all contract notifications for Settlement Periods 39 to 43 (inclusive) for 13 May 2020 before 19:15 (BST) on 13 May 2020.

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?


The scheduled ECVAA reports are not impacted by the planned downtime.

Will the contents of any of the reports I receive be different?


The ECVAA Notification Report (ECVAA-I014) for 13 May 2020 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, shortly after the downtime.

Will there be any further communications about this downtime?


We will keep the Elexon Portal updated and will publish a further update on 13 May 2020 when the downtime is finished.
