Long-Term 2 RFP

Ontario’s electricity sector today is seeing growing demand, an evolving supply mix and a drive toward grid decarbonization. Combined, these factors are spurring the IESO’s ongoing large-scale resource acquisition effort to ensure sufficient supply will be available into the 2030s and beyond.

While recent procurements have focused on capacity, which seeks forms of supply that are capable of meeting demand specifically during system peak hours, planning forecasts indicate both energy and capacity needs emerging in 2029 and beyond. Over the next few years, the IESO expects to run multiple RFP submission windows, each under a distinct request for proposals, under the umbrella of the LT2 RFP, to procure resources to meet system needs.
