IT notices: Planned National Grid ESO Outage

We have been notified by National Grid ESO that there will be a Market Operation Data Interface System (MODIS) planned maintenance outage between 01:00 (GMT) and 05:00 (GMT) on Saturday 23 November 2019.

How will I be affected?

During the outage, MODIS will be impacted. MODIS sends Loss of Load Probability (LoLP), De-rated Margin (DRM), REMIT and Transparency data from National Grid to the Balancing Mechanism Reporting Service (BMRS) however, LoLP and DRM information should not be affected during this outage.

Market Participants will be unable to submit European Transparency Regulation (ETR) and REMIT data to MODIS via FTP. 

Furthermore, ETR, REMIT and Non-BM STOR data will not be published on BMRS during this period of downtime. These files will be updated once the outage is completed.
Participants who submit REMIT data via the Elexon Portal will not be impacted and National Grid’s Balancing Mechanism (BM) systems will also be unaffected by this planned downtime.

What do I need to do?

You do not need to take any specific action but just note the impact of the outage.

Do I need to take any further action?

No, however any BSC Parties having questions for National Grid regarding this planned outage should phone 0800 917 7111 or 0800 085 4806. Overseas callers should use +44 870 521 6121 and quote “NETA EDT”.
