Historical electricity rates

COVID-19 UPDATE - New electricity pricing for TOU customers begins June 1

To support families, small businesses and farms while Ontario plans for the safe and gradual reopening of the province, the Government of Ontario has introduced a new fixed electricity price of 12.8 ¢/kWh for customers that are on time-of-use (TOU) prices. Starting June 1, 2020, that price applies to electricity used at all hours of the day, seven days a week. Having the same price apply at all hours of the day is a more predictable way to pay for power at a time when Ontarians continue to work and learn from home.

Tiered rates

The following table and chart tracks tiered electricity rates. Time-of-use rates started to replace tiered rates for households and small businesses in 2005. Under tiered rates, customers are charged two rates for electricity: a lower rate for the electricity used up to a certain limit, and a second, higher rate for all additional use.

May 1, 2020 - Due to COVID-19, winter tier prices and thresholds remain in place until further notice. By keeping the winter threshold in place, customers have an additional 400kWh/month available at the lower price. Read more
