Market Development Advisory Group

Resource Acquisition

The IESO has created a new Market Development Advisory Group (MDAG) which will support IESO efforts to evolve the Ontario electricity market, beyond the Market Renewal Program, to cost-effectively ensure reliability in the near and longer terms. See the Terms of Reference for additional context.

The MDAG will take a forward-looking approach to its discussions by:

  • Discussing group member and IESO market experience and technical expertise from Ontario and other electricity markets
  • Providing guidance and advice that support the development and evolution of the IESO markets in accordance with the future market vision
  • Informing the IESO on broader sector developments that may impact the IESO’s approach to market development
  • Providing input to the Work Plan

All enquiries, comments and nominations can be directed to
