When electricity is at peak demand (like it is now) conserving or postponing consumption until off-peak hours is a good idea. This lightens the load on the provincial grid and saves you money.

Prices effective November 1, 2016

Off-Peak: 8.7 cents/kWh Mid-Peak: 13.2 cents/kWh On-Peak: 18.0 cents/kWh

Time-of-Use rates are designed to promote conservation and reduce peak demand for electricity. Peak demand happens when we all use electricity at the same time. Unlike most commodities, electricity cannot be stored and must be generated in real time to meet Ontario's needs.

With Time-of-Use rates, there is a financial incentive for you to conserve energy and to shift some consumption away from on-peak periods.

Reducing peak demand is good for the environment because the power plants used to meet peak demand are usually fossil-fuel generating stations. Using them less will mean less greenhouse gases and in the long run, it will also save money. It's expensive to build and maintain power plants that only operate during peak periods.

The rate periods are different in the summer and winter months.

Summer Weekdays (May 1 to October 31)

The highest energy prices occur over the afternoon, when air-conditioning use is greatest.

Summer Weekdays (May 1 to October 31)

Winter Weekdays (November 1 to April 30)

There are two peak periods during the winter months: in the early morning and in the evening. During these times, increased space heating, lighting and appliance use is common.

Winter Weekdays (November 1 to April 30)

Weekends and Holidays

These periods are all off-peak, both summer and winter. View the current Holiday Schedule.
