Market Participant Update Document (MPUD) - SEM R2.2.0 - Revision V1.2 

As highlighted at the Market Test workshop on February 26th, a minor update is required to the MPUD Reporting Volume in relation to the TLAF Report in CR193. As a result SEMO is issuing a revision to the Market Participant Update Document to reflect this update. A summary of the update can be found in the MPUD Cover Note here.

SEMO is responsible for the maintenance and management of the MPUD documentation suite and welcomes feedback and suggestions in relation to this at any time. Any correspondence relating to the MPUD and associated volumes should be submitted to the SEMO Market Helpdesk (, title prefixed with the word “MPUD”.
