IT notices: Planned BMRS downtime for deployment of P344 on 28 May 2020

Further to BSC Bulletin 339, the end time for the deployment outage on the Balancing Mechanism Reporting Service (BMRS) today, has been changed from 01:00 (BST) to 02:00 (BST). Therefore the period of downtime on the BMRS will take place between 18:57 to 02:00 (BST) today, 28 May 2020.

This downtime is required to implement BSC Modification P344 (Project TERRE implementation into GB market arrangements) in the BSC Central Systems and BMRS.

The full scope is available on the Modification P344 page of the Elexon website. 

How will I be impacted?

During the period of planned downtime, the BMRS will not load or publish data via the website, APIs and Data Push Service. In addition, users of the TIBCO service will not receive any TIBCO messages via their High Grade Communications Lines and European Transparency Regulation (ETR) data will not be sent to ENTSO-e Transparency Platform during the outage. 

Please note that you can continue to submit REMIT data via the Elexon Portal during this planned downtime, where the data will be accepted, queued and sent in sequence, however these files will be delayed by this planned downtime. The remaining BSC Central Systems are unaffected by this planned downtime.

Is there anything else I need to know?


Shortly after the completion of the outage, Elexon will carry out post-deployment business process checks and further communications will be issued. The BMRS will start processing the backlog and we expect website and APIs will be fully updated by approximately 03:05 (BST) on 29 May 2020.

Do I need to take any further action?
