BSC Bulletin 339 - Planned BMRS downtime required for the deployment of P344 Project TERRE Release
What is happening?
There will be a period of planned downtime on the Balancing Mechanism Reporting Service (BMRS) from 18:57 to 02:00 (BST) on Thursday 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 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.
Will there be any further communications about this BMRS downtime?
ELEXON will send a follow-up Circular if there are subsequent changes to this deployment.
Is there anything else I need to know?
Yes, 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 03:00 (BST) on 29 May 2020.
Do I need to take any further action?
No, for more information on this Circular, please contact the BSC Service Desk.
