Energy resources at both the transmission and distribution level are contributing factors to a reliable grid. Here is an overview of supply in the province, including access to historical information.
This interactive illustration showcases the many components that make up Ontario's electricity system. Each component provides different information, for example, Ontario’s 21 energy planning regions, transmission, grid-connected generation facilities over 20 MW, and the oil and gas pipeline network.
Energy and Capacity RFPs and Transmission Development
This interactive map highlights all the successful RFP projects awarded through the IESO's ELT1, LT1, LT2, MT1, and MT2 procurements. The transmission layer provides visibility into transmission projects identified through bulk and regional planning initiatives that are under consideration, recommended for development, in progress, under construction, or completed, helping to support Ontario's growing and evolving electricity needs.
The Wind Power in Ontario illustration demonstrates how wind power is contributing to the province’s electricity needs. It shows the forecast hourly wind output at a regional and province-wide level over the next 48 hours. It also shows the last available hour’s output of each wind facility, updated approximately 30 minutes past the hour.
