Ontario's Largest Competitive Electricity Procurement is Underway
July 3, 2025
The first of four annual procurement windows for the IESO’s second Long-Term Request for Proposals (LT2 RFP) is now open, targeting 3 TWh of energy and 600 MW of capacity with a submission deadline of Thursday, Oct. 16, 2025, for energy and Thursday, Dec. 18, 2025, for capacity.
The LT2 RFP is open to all resource types and will build on Ontario’s already diverse supply mix, with resources expected to be in-service beginning in 2030.
Engagements on the LT2 RFP began in December 2023, and the procurement design incorporates feedback from prospective market participants, resource developers, municipalities and Indigenous communities. The IESO extends its gratitude to everyone that has taken part and contributed to this massive undertaking to date.
The LT2 RFP reflects a new directive from government authorizing the launch of the first window and outlining the addition of weighted evaluation criteria to support Canadian companies.
