Planned downtime of BSC Central Systems from 18:57 (GMT) on Tues 10th Dec to 00:45 (GMT) on Wed 11th Dec 2019
Planned downtime of BSC Central Systems on 10 and 11 December 2019 for deployment of the Wider Access Standalone Release
What is happening?
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) and Central Registration Agent (CRA). This period of planned downtime has been changed to minimise impact on Intraday trading following feedback received from customers.
How will I be impacted?
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.
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:
â Settlement Periods 39 to 48 (inclusive) for 10 December 2019; and
â 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 Report (ECVAA-I022), scheduled to run at 22:00 (GMT) on 10 December
2019, will be suspended. An ECVAA-I022report will be run after the outage at 01:00 (GMT) on 11 December.
Will there be any further communications about this BSC Agent downtime?
Yes, we will keep the ELEXON Portal updated on 11 December 2019 when the downtime is finished.
Is there anything else I need to know?
Following completion of the downtime, 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.
