Connecting Today.
Powering Tomorrow.
The Independent Electricity System Operator (IESO) works at the heart of Ontario's power system. The IESO delivers key services across the electricity sector including: managing the power system in real-time, planning for the province's future energy needs, enabling conservation and designing a more efficient electricity marketplace to support sector evolution.
Long-Term 2 RFP
The IESO’s ongoing large-scale resource acquisition efforts are designed to ensure sufficient supply will be available into the 2030s and beyond. Over the next 4-6 years the IESO expects to run a regular cadence of procurements, beginning with the second long-term RFP (LT2), which will look for about 2,000 MW of energy-producing resources.
2024 Annual Planning Outlook
The IESO’s 2024 Annual Planning Outlook identifies system needs and planned actions from 2025 to 2050 that are needed to ensure the reliability, affordability and sustainability of Ontario’s electricity system. With significant progress being made to address these needs, the IESO is also providing an update of its emissions forecast for the sector. See Six Graphs and a Map from the 2024 APO and an Emissions Update.
