Possible National Grid MODIS Downtime: Thursday 11 October 2018

What is happening?
National Grid has informed us that there may be a short period of downtime on the Market Operation Data Interface System (MODIS) on Thursday 11 October 2018 between 13:00 - 16:30 (BST).

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).  

How will I be impacted?
Users will still be able to submit data via SFTP to MODIS during the downtime and this data will be processed normally during the outage. In addition, users can still login normally via the web application and REMIT and ETR submissions will be sent to BMRS during this outage.

There is a slight possibility that half hourly LoLP and DRM data publication could be affected for some or all of this outage period. National Grid aims to deploy the update between half hourly runs to avoid any impact on reporting. In addition, this data should be able to be sent manually if required, but if this is not possible, any affected runs will not be published retrospectively, which is in accordance with the BSC. 

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?
Parties are not required to take any further action but note the potential impact of this planned downtime on LoLP and DRM data publication.
