IT notices: Downtime of BSC Central Systems

There will be a period of planned downtime on the BSC Central Systems applications from 18:57 (GMT) on Tuesday 10 December to 00:45 (GMT) on Wednesday 11 December 2019.

This BSC Central System downtime is required for Wider Access deployment and will impact the:

  • Balancing Mechanism Reporting Service (BMRS)
  • Energy Contract Volume Aggregation Agent (ECVAA)
  • Settlement Administration Agent (SAA)
  • Supplier Volume Allocation Agent (SVAA)
  • Central Data Collection Agent (CDCA)
  • Central Registration Agent (CRA)

How will I be impacted?

BMRS

During the period of planned downtime, the BMRS website will not publish data via the website, the API, Data Push services and European Transparency Regulation (ETR) data will not be sent to ENTSO-e Transparency Platform. In addition users of the TIBCO service will not receive any TIBCO messages via their High Grade Communications Lines.

Although the BMRS will not be available, the Elexon Portal POST API interface for submitting REMIT files to BMRS will still be available. Parties can continue using the POST API to submit REMIT data which will be available on the BMRS website upon completion of the outage.

ECVAA

The 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 not be processed and the ECVAA Credit Cover Percentage check will also be suspended for the duration of deployment.

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. ECVAA reports e.g. Notifications Report, Forward Contract Report will resume after 01:00 (GMT) on 11 December 2019.

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 10 December; this will include ECVNs/MVRNs for the following:

  • Settlement Periods 39 to 48 (inclusive) for 10 December 2019; and
  • Settlement Period 1 for 11 December 2019.

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 2 on 11 December 2019, as there is only 15 minutes between the end of the downtime and Submission Deadline for Settlement Period 2.

Will I receive ECVAA reports as normal?

No, the ECVAA Forward Contract Reports (ECVAA-I022), scheduled to run at 22:00 (GMT) on 10 December 2019, will be suspended. An ECVAA-I022 report will be run after the outage at 01:00 (GMT) on 11 December.

Will there be any further communications?

Elexon will send a follow-up Circular on the 11 December when the downtime is finished.

Is there anything else I need to know?

Following completion of the outage, BMRS will start processing the backlog of data and we expect the BMRS to be fully recovered by 02:00 (GMT) on the 11 December 2019.
