This is the latest on the integration of repowered facilities in the second window of the Independent Electricity System Operator’s (IESO) Long-Term 2 (LT2) Request for Proposals (RFP) and Medium-Term 3 (MT3) RFP.
Eligibility
In late 2025, the IESO advised that repowered facilities would be ineligible to participate in the first window of the LT2 RFP (i.e., LT2(e-1) and (c-1)), but that steps would be taken to integrate participation by repowered facilities in the second window of the LT2 RFP (i.e., LT2(e-2) and (c-2)).
The IESO has since announced it will indeed be offering an LT2(e-2) and (c-2) RFP stream for repowered facilities with a cap of 1 terawatt. This is in addition to the procurement target of 1 to 3 TWhs for new-build facilities, which will proceed by way of its own separate stream to ensure they remain competitive against the project development cost advantages that already existing facilities may have.
