Engaging the Sector

The IESO regularly seeks input from stakeholders and community representatives on initiatives that affect them. We do this through a variety of forums, including the Stakeholder Advisory Committee (SAC) whose members represent interested energy sector parties.

At the August 23rd SAC meeting, market renewal and the mid-term review of Ontario’s conservation framework were discussed. Participants also heard from Michael Cleland with the University of Ottawa’s Positive Energy Project who discussed the efforts to strengthen public confidence in energy decision-making.
