Planned downtime required for the March 2021 Standalone (P408) BSC Release deployment
What is happening?
There will be a period of planned downtime on the Balancing Mechanism Reporting Service (BMRS) from 18:57 (GMT) to 22:00 (GMT) on Wednesday 17 March 2021.
This period of planned downtime is required to implement BSC Modification P408 (Simplifying the Output Usable Data Process) as part of the March 2021 Standalone BSC Release. The scope of the release 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.
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.
Following this planned downtime Elexon will carry out post deployment business process checks. The BMRS will start processing the backlog of data. We expect the BMRS website and APIs will be fully updated by approximately 23:00 (GMT) on 17 March 2021.
Is there anything else I need to know?
P408 will improve market transparency and efficiency through provision of additional Output Usable, Margin and Surplus data in the two to three year ahead reports (2-156 weeks ahead) on the BMRS Website, API, Data Push Service and TIBCO. The existing zonal output useable data will be decommissioned from BMRS as part of this change. The details for the new APIs are included in API and Data Push User Guide (Version 5).
