IT notices: Planned downtime required for the deployment of November 2021 Release

There will be a period of planned downtime on the Balancing Mechanism Reporting System (BMRS) from 3 November 2021 at 23:00 (GMT) to 4 November 2021 at 01:30 (GMT).

This is the second of two BMRS downtimes required for the deployment of November 2021 Release.

How will I be impacted?

During the outage window, BMRS will not publish any data received from National Grid ESO or REMIT data from the Elexon Portal. Users of the BMRS APIs, TIBCO and Data Push Service will not receive the latest data set.

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, publication of these files will be delayed by this planned downtime.

Is there anything else I need to know?

You do not need to take any specific action and we will perform system checks following completion of the work.

The November 2021 Release includes implementation of Modification P399 (BSAD Identity Visibility) which will be reflected in Disaggregated Balancing Services Adjustment Data (BSAD) reports from BMRS and also included in the Settlement Administration Agent (SAA) Settlement Report (SAA-I014). The full scope for November 2021 Release is available on the Elexon website.
