Q2 2022 Reliability Outlook Now Available

June 23, 2022

Ontario is expected to have an adequate supply of electricity to meet the needs of residents, businesses and communities for the next 18 months. However, the province has entered a period of tighter electricity supply conditions that will require active outage management and increased import volumes during certain periods.

Total consumption in 2022 is expected to reach 136.0 terawatt-hours (TWh), an increase of 1.7% over 2021. The demand forecast continues to evolve in response to inflation, supply chain disruptions and geopolitical tensions, among other factors. The IESO is monitoring the situation and will adjust the forecast as needed

On the supply side, concurrent nuclear outages coupled with regional transmission constraints have reduced the amount of supply available to meet the province’s energy needs. Discussions with nuclear generators are ongoing and the refurbishment schedule for 2023 is expected to change, resulting in an improved adequacy outlook. New wind and hydroelectric resources will also be available to help meet demand.

The full report is available on the IESO website.
