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.
Ontario's power system is operating reliably through the COVID-19 pandemic. Please check this site for updates.
The IESO’s Annual Planning Outlook (APO) assesses Ontario’s electricity system over the long term, examining future needs and the factors that influence them. This year’s 20-year forecast discusses how evolving sources of demand and the changing supply mix affect plans for future reliability.
Ontario electricity users are starting to see the benefits of investing in technologies that can help manage their consumption – and their costs. New research shows that already a third of all Ontario electricity consumers are using some form of technology that enables them to control their energy use in ways that can save money and help meet system needs.
