Q3 2021 Reliability Outlook Now Available

September 23, 2021

Despite the ongoing pandemic, demand for electricity in Ontario has been robust throughout 2021. Marking a significant shift for the province, demand is now expected to increase 1.1% in 2021, and another 1.4% in 2022, after years of declining annual consumption.

The IESO is forging ahead with solutions to manage the forecasted demand growth identified in this outlook. Included in these efforts are target capacities for the upcoming Capacity Auction of 1,000 MW for the summer 2022 obligation period, and 500 MW for the winter 2022/2023 obligation period.

Despite the many changes underway that affect demand, supply and transmission, the IESO is confident in its ability to manage changing grid conditions to ensure reliability for the period covered by this Outlook. The full report is available on the Planning and Forecasting web page.
