IT Notice: Planned National Grid ESO MODIS Outage on 21 August 2021

We have been informed by National Grid ESO (NGESO) that there will be a planned outage on the Market Operation Data Interface System (MODIS) between 01:00 and 05:00 (BST) on Saturday 21 August 2021.

Is there anything else I need to know?

MODIS sends Loss of Load Probability (LoLP), De-rated Margin (DRM), REMIT and European Transparency Regulation (ETR) data from National Grid to the Balancing Mechanism Reporting Service (BMRS) and this will all be affected during this outage.

Processing of all Market Participants (ETR & REMIT) reports submitted to MODIS will be delayed until the end of the outage and hence files will not be published to BMRS during the outage.

Backlog data received and routine reporting for each maintenance window will be processed as soon as possible to catch up after each outage.

Do I need to take any further action?

No, however any BSC Parties with 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”.
