Technical Support Group - Enhanced Day-Ahead Commitment

The objective of this Technical Support Group (TSG) is to offer comments on the design for the enhanced day-ahead commitment (EDAC) project. 

Members of the TSG will review the materials provided by the IESO EDAC project team and provide detailed technical advice to the IESO in an efficient and timely manner.  Guidance from the TSG will be reflected in updates to the high level design document, to the Stakeholder Advisory Committee (SAC) and the IESO’s recommendations to the Board of Directors.

Background information on day-ahead market evolution can be found here.
