Planned downtime for BSC Central Systems on 14 November 2018
What is happening?
There will be a period of planned downtime on the BSC Central Systems applications from 01:57 (GMT) to 09:15 (GMT) on Wednesday 14 November 2018. This is the first of two BSC Agent downtimes required for 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). The second BSC Agent downtime is planned overnight on 27–28 November 2018.
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. TIBCO service users will also 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 09:15 (GMT) on 14 November 2018.
What do I need to do?
You will need to arrange to submit ECVNs or MVRNs for Settlement Periods 5 to 19 (inclusive) on 14 November 2018 before the start of the BSC Agent Downtime. Please do this as early as possible to reduce the risk of missing the Submission Deadline. You may also wish to submit contract notifications for Settlement Period 20, 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 09:00 (GMT) on 14 November 2018, will be suspended. Instead, the report will run after the outage at 09:30 (GMT).
The ECVAA Notification Report (ECVAA-I014), scheduled to run at 02:00 (GMT) on 14 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 14 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 14 November 2018 when the downtime is finished.
Is there anything else I need to know?
To complete the technology upgrade on the BSC Central Systems, another downtime will be required overnight on 27 - 28 November 2018 and we expect this to last 12 hours. We will issue a News Item confirming the details next week.
