Market Renewal Program Project Status

Ontario benefits from a wholesale electricity market that has enabled reliable and cost-effective operation of the electricity system over the past 20 years. The value of the wholesale market will continue to grow as the electricity sector transforms over the next decade.

To realize this increasing value, the Market Renewal Program (MRP) is designed to address existing inefficiencies and modernize the wholesale market enabling it to support the integration of an increasingly diverse and decentralized mix of resources. These changes will deliver significant ratepayer savings and ensure continued reliable operations as the system becomes more diversified and complex.
