IT notices: Planned downtime on National Grid infrastructure 23-24 July 2019

There will be a period of planned downtime impacting the Balancing Mechanism Reporting Service (BMRS) from 18:00 (BST) 23 July 2019 to 04:00 (BST) 24 July 2019. This is required for National Grid ESO and ELEXON to carry out essential infrastructure maintenance on the communications line.

How will I be impacted?

During the outage, the communications between BMRS and National Grid ESO applications which includes Balancing Mechanism (BM) and Market Operation Data Interface System (MODIS), will be suspended and BMRS will not receive the data.

Therefore, all data normally received from National Grid ESO applications will not be updated via the BMRS Website, APIs, Data Push Service and TIBCO. This includes REMIT and European Transparency Regulation (ETR) data sent from National Grid’s MODIS system and as a result, there will be a delay in BMRS sending ETR to ENTSO-e Transparency Platform from the BMRS.

Furthermore, Settlement Calculations will be suspended on the BMRS and be restarted at the end of the outage.

Please note that there will be periods during this outage where service may become available intermittently; however a full service will only resume once the outage is completed.

What do I need to do?

You do not need to take any specific action but just note the impact to parties during this planned outage.

After the downtime

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 04:00 (BST) on 24 July 2019 as we exit the outage.

Not impacted

Parties who currently use the ELEXON 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.

The remaining BSC Central Systems are not affected by this planned downtime.

Electronic Data Transfer (EDT) and Electronic Data Logging (EDL) interfaces between BSC Parties and National Grid ESO will not be affected and Parties will be able to submit data as usual. Any BSC Parties having questions for National Grid ESO regarding EDT and EDL submissions, should phone 0800 917 7111 or 0800 085 4806. Overseas callers should use +44 870 521 6121 and quote “NETA EDT”.
