IT notices: Planned downtime – deployment of December 2019 Standalone BSC Release

There will be a period of planned downtime on the Balancing Mechanism Reporting Service (BMRS) from 18:57 (GMT) to 22:00 (GMT) on Tuesday 17 December 2019. This period of planned downtime is required to implement the December 2019 Standalone BSC Release; which includes:

  • BSC Modification P384 (Publication of European Electricity Balancing Guideline balancing data by BMRS)
  • Change Proposal CP1516 (New Interconnector Fuel Type Categories: ElecLink and IFA2)

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?

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 23:00 (GMT) on Tuesday 17 December 2019.
