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 always 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.

It’s expensive to build and maintain power plants that only operate during peak periods. Using time-of-use structure helps in shifting consumption, creating an equalized demand through out the day which saves on operating costs.

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