EL03469 - Planned infrastructure maintenance on BSC Central Systems
What is happening?There will be a planned period of downtime on the BSC Central Systems applications from 23:57 (GMT) on Friday 3 December 2021 to 06:15 (GMT) on Saturday 4 December 2021. This outage is required for infrastructure maintenance on the BSC Central Systems applications including the Energy Contract Volume Aggregation Agent (ECVAA), Settlement Administration Agent (SAA), Central Data Collection Agent (CDCA) and Central Registration Agent (CRA).
The Balancing Mechanism Reporting Service (BMRS) will be accessible throughout, but data updates will be suspended during the planned downtime.
How will I be impacted?
ECVAAThe ECVAA application and ECVAA Web Service (EWS) will be impacted by the outage and in accordance with the procedures, common submission of Energy Contract Volume Notification (ECVN) and Metered Volume Reallocation Notification (MVRN) to ECVAA will be blocked and the ECVAA Credit Cover Percentage check will also be suspended. Following completion of the outage, the ECVAA Credit Cover Percentage check will be re-enabled and submission of ECVNs and MVRNs will be processed as normal.
BMRSDuring the period of planned downtime, no data will be received via the Data Push and TIBCO services, the API and website will be available but will not publish the latest data. Following completion of the planned downtime, the BMRS will resume data updates and the data for all impacted settlement periods will be published as part of the normal BMRS recovery.
Elexon PortalAll Elexon Portal logins will be disabled during the period of planned downtime.
What do I need to do?You will need to arrange to submit ECVNs or MVRNs before the start of the BSC Agent Downtime on 3 December 2021; this will include ECVNs/MVRNs for Settlement Periods 1 to 13 (inclusive) for 4 December.
Please do this as early as possible to reduce the risk of them missing Submission Deadline. You may also wish to submit contract notifications for Settlement Period 14 on 4 December before the downtime, as there is only 15 minutes between the end of the downtime and the Submission Deadline for Settlement Period 14.
Will I receive ECVAA reports as normal?No, the ECVAA Notification Report (ECVAA-I014), scheduled to run at 02:10 (GMT) will be suspended. The report will instead be run after the planned downtime at 07:00 (GMT).
Will the contents of any of the reports I receive be different?Yes, the ECVAA Notification Report (ECVAA-I014) for 4 December 2021 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 in normal mode.
Will there be any further communications about this downtime?Yes, we will keep the Elexon Portal updated and will publish a further Circular on 4 December when the outage is complete.
