Market Renewal – Single Schedule Market

The IESO invites stakeholders to participate in and provide feedback on the design and development of a single-schedule energy market. The replacement of IESO’s current two-schedule market with a single-schedule design is a key foundational element of the IESO’s Market Renewal Program (MRP).

The IESO encourages all stakeholders in Ontario's electricity sector, or their representatives, with an interest in this initiative to participate in this engagement. This initiative will consider fundamental market design issues and changes; it will be of interest to all IESO market participants and related stakeholders.

All comments and enquiries in this stakeholder engagement can be directed to
