Introducing the IESO Renewed Market

The IESO has improved the way electricity is scheduled and priced across the province. These changes ensure we can continue to make the most cost-effective use of our supply every hour of every day as the grid expands to meet growing demand and incorporate new technologies.

Ontario’s largest competitive procurement for new electricity generation and capacity is now open  through the IESO’s second Long-Term Request for Proposals. The IESO is currently seeking energy and capacity from new-build resources, to be hosted in supportive communities across the province, in the first of four procurement windows.
