The Ontario Energy Board (OEB) sets the province’s prices for electricity under the Regulated Price Plan (RPP)* and develops the daily and seasonal TOU periods. With TOU pricing electricity prices vary, based on when it is used. That includes by time of day, by day of week (weekdays versus weekends), and by season (winter or summer). TOU prices provide customers with a way to manage electricity costs, reduce strain on the electricity system and help the environment.

On July 1, 2017, revised pricing for on-, mid-, and off-peak pricing came into effect under Fair Hydro Plan legislation, further reducing the cost of electricity. Find out More.

Summer TOU periods and prices take effect from May 1 to October 31. Winter TOU periods and prices take effect from November 1 to April 30.

*NOTE: For electricity customers on a fixed-term contract with an electricity retailer, TOU prices do not apply.
