Software Technical Advisory Group (STAG)

ELEXON, in partnership with its Application Maintenance and Development (AMD) service provider, develops and maintains software used by Party Agents in the Non Half Hourly (NHH) Supplier Volume Allocation (SVA) market:

  • Non Half Hourly Data Aggregator (NHHDA) software used by NHHDAs;
  • Estimated Annual Consumption / Annualised Advances (EAC/AA) software used by NHH Data Collectors (NHHDCs); and
  • Erroneously Large EAC/AA Reporting Tool (ELERT).

We hold STAG meetings to provide users of this software with a forum to discuss current and relevant issues. Meetings are held at our offices from 10:30 to 13:00, typically every alternate month providing there is sufficient business.

If you would like more information regarding STAG meetings or attendance, please contact BSC.Admin@elexon.co.uk. We will publish the agenda, minutes and all public papers viewed by the STAG at the links below, typically within one week following the date of the meeting.

If you are an NHHDA or NHHDC who does not wish to attend the STAG but would like to be added to our distribution list for users of the Party Agent software, which we use to communicate information about change releases, software upgrades and fixes, please email releases@elexon.co.uk.
