Medium-Term RFP

The IESO has concluded the first medium-term RFP, and has offered new MTC I Contracts, for five-year commitments, to six existing resources that are currently off-contract or coming off contract. The continued use of existing facilities is a cost-effective way to help address immediate electricity supply needs, as well as ensuring these facilities continue to support reliability in Ontario.

The MT I RFP registration period ran from January 31 to February 22, 2022, and the IESO received registrations from twelve Qualified Applicants. The MT I RFP Proposal Submission Deadline was April 28, 2022, and the IESO received seven Proposals, which included four natural gas facilities, two energy storage facilities, and one wind facility.

This year’s medium-term RFP has offered contracts to six wind, storage and natural gas facilities. Together these facilities contribute more than 700 MW of capacity to the system, ensuring ongoing value from previous investments in supply. This supply will be available between 2024 – 2026, at a lower cost than previous contracts. This procurement will complement other supply acquisition activities to meet reliability targets over the same timeframe.

The IESO will continue to run a series of cadenced medium-term RFPs every two to three years, with flexible five-year commitment periods in order to secure resources with expiring contracts. Future medium-term RFPs will evolve based on system needs and will likely see increased resource eligibility and competition. Procurement designs will continue to be shaped by input from stakeholders through the Resource Adequacy Engagement, as well as other IESO assessments and engagements.
