Ontario’s Independent Electricity System Operator (IESO) has announced it has secured over 1.3 GW of energy from 12 solar projects and 2 wind projects, through the province’s Long-Term 2 (LT2) Energy Window 1 procurement exercise (IESO press release, 10/04/2026).
- The 12 solar projects have a combined capacity of 915 MW, while the two wind projects total 400 MW. The approved solar projects range from 9 MW to 200 MW in capacity and include four projects over 100 MW in size, while the two wind projects account for 200 MW each.
- Together, they are set to add more than 3 TWh/year of new power generation to Ontario’s grid. Projects are set to come online by 2030. Each of the projects includes at least 50% Indigenous equity ownership.
- This latest deal for 1.3 GW is one round of the broader LT2 process that aims to secure up to 7.5 GW of new electricity supply by 2029.
The government of Ontario is focusing its energy future on natural gas and nuclear. Under the province’s energy plan, reliance on fossil fuels is expected to increase over the next decade, with emissions expected to rise before declining after 2030. The province is also investing billions to reconstruct its existing nuclear reactors and is planning large new units and small modular reactors to cover future electricity demand. Ontario projects more than 70% of its electricity will be nuclear by 2050, up from about 50% today (Canada's National Observer, 13/04/2026).
