ELEXON Circular EL02920:
Planned downtime for BSC Central Systems on 27 and 28 November 2018

What is happening?
Further to ELEXON Circular EL02911, there will be a period of planned downtime on the BSC Central Systems
applications from 20:57 (GMT) on Tuesday 27 November to 09:15 (GMT) on Wednesday 28 November
2018. This is the second of the two BSC Agent downtimes required for the implementation of the technology
upgrade of the BSC Central Systems applications including 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).

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 once the downtime has completed.

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 09:15 (GMT) on 28 November 2018.

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 27 November
2018; this includes ECVNs/MVRNs for the following:

  • Settlement Periods 43 to 48 (inclusive) for 27 November 2018; and
  • Settlement Periods 1 to 19 (inclusive) for 28 November 2018.

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 20 on 28 November 2018, as there is only 15 minutes between the end of the downtime and Submission Deadline for Settlement Period 20.

Will I receive ECVAA reports as normal?
No, the ECVAA Forward Contract Reports (ECVAA-I022), scheduled to run at 22:00 (GMT) on 27 November
2018 and 09:00 (GMT) on 28 November 2018, will be suspended. Instead, a single report will run after the
outage at 09:30 (GMT).
The ECVAA Notification Report (ECVAA-I014), scheduled to run at 02:00 (GMT) on 28 November 2018, will also
be suspended and will run after the outage at 10:00 (GMT).

Will the contents of any of the reports I receive be different?
Yes, the ECVAA Notification Report (ECVAA-I014) for 28 November 2018 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 BSC Agent downtime?
Yes, we will keep the ELEXON Portal updated and will publish a further Circular on 28 November 2018 when the
downtime is finished.
