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.
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.
There is one mid-day peak period in the Summer During this time air conditioning usage is at its highest.
These periods are all off-peak, both summer and winter. View the current Holiday Schedule
