IT notices: Downtime for BSC Central Systems on 3 September 2019

Name: IT notices: Downtime for BSC Central Systems on 3 September 2019
Start: 2019-09-03T17:57:00+00:00
End: 2019-09-03T21:45:00+00:00

There will be a period of planned downtime on the BSC Central Systems applications from 17:57 (BST) to 21:45 (BST) on 3 September 2019. The outage is required for essential maintenance to the Energy Contract Volume Aggregation Agent (ECVAA), Funds Administration Agent (FAA), Settlement Administration Agent (SAA), Central Data Collection Agent (CDCA) and Central Registration Agent (CRA).

How will I be impacted?

BMRS

During the outage, the BMRS will not receive data from the National Grid Balancing Mechanism (BM), which will therefore not be updated via the BMRS Website, APIs, Data Push Service and TIBCO. Furthermore, Settlement Calculations will be suspended on the BMRS and be restarted at the end of the outage.

Parties who currently use the ELEX1)ON Portal POST API interface to submit REMIT files to the BMRS will not be impacted by this outage and the data will continue to be published on the BMRS as normal.

Following this planned downtime, the BMRS will start processing the backlog during the end of the outage period and we expect the BMRS website and APIs will be fully updated by 23:00 (BST) on 3 September 2019 as we exit the outage.

ECVAA

The ECVAA application and ECVAA Web Service (EWS) will be impacted by the downtime 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 downtime, 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 21:45 (BST) on 3 September 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 3 September 2019; this includes ECVNs/MVRNs for Settlement Periods 37 to 43 (inclusive).

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 44, as there is only 15 minutes between the end of the downtime and Submission Deadline for Settlement Period 44.

Will I receive ECVAA reports as normal?

No.

The ECVAA Forward Contract Reports (ECVAA-I022), scheduled to run at 18:30 (BST) on 3 September 2019. Instead, a single report will run after the outage at 22:00 (BST) on 3 September 2019.

Will the contents of any of the reports I receive be different?

No.

Will there be any further communications about this BSC Agent downtime?

Yes.

We will keep the Elexon Portal updated and will publish a further Circular on 4 September 2019 when the downtime is finished.
