Market Renewal - Incremental Capacity Auction

The IESO invites stakeholders to participate in and provide feedback on the design and development of an Incremental Capacity Auction (ICA). The ICA Project will develop an enduring market-based mechanism that will secure the capacity needed to ensure Ontario’s resource adequacy needs are met cost effectively. Developing an ICA is a key 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 including registration to participate can be directed to
