Viewing & Filtering UMM's

Published on Friday 25th August 2017 at 2:56pm National Grid

After recent trials the GB REMIT portal has some new added features around viewing & filtering UMMs.  Users are now able to filter UMMs more specifically and this can be done by using any of the fields that are available in the new ACER Schema. Also users can view by a Tabular View or download via a CSV file.


These improvements were made at the request of the industry and are live as of 23.8.17


As always contact us at with your views.


UMM Uploading by XML

Published on Monday 12th June 2017 at 11:11am National Grid

Following requests from users of the National Grid Remit site to allow XML loading of Urgent Market Message (UMM), today the new process for uploading UMM, via XML has gone live. Some members of the community responded to our request to test, and this passed. Thank you to those who did test and helped to get to this stage. 


This XML Load process will facilitate a second method of uploading UMM and does not replace the current option of manually uploading. The user Provider User Guide has been updated and this can be found in the the Useful Information section of the site. If you require any support through this new process, can you go to the "Contact" section of the site and complete the form and we will look into your query with the support of our providers.


Thank You.
