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, there is also a need for actual energy output during periods throughout the year. Over the next 4-6 years, the IESO expects to run a regular cadence of procurements. The first of these procurements, the second long-term RFP (LT2), will look for about 2,000 MW of energy-producing resources.
