Resource Acquisition and Contracts

Ontario’s electricity sector continues to see a growing demand into the 2030s and beyond due to increasing industrial demand, data center growth and electrification. To meet these needs while maintaining flexibility, the IESO has taken a multi-pronged approach to secure energy and capacity resources under various term lengths.

Recent procurements have focused on securing medium term and long-term resources with 5- and 20-year term lengths respectively. The Long Lead-Time Request for Proposals (LLT RFP) is intended for eligible resources with unique development considerations that require longer lead times for project development and longer-term lengths, aligned with the expected resource lifetime.
