Electricity Rates and Charges

Time-of-Use Rates Effective July 1, 2017 to December 31, 2017

The majority of Oakville Hydro’s residential and small business customers are billed based on time-of-use rates.  If you have signed a contract with an electricity retailer you will pay contract rates. For those customers on time-of-use rates, there are three price periods:

  • Off-peak, when demand for electricity is lowest.
  • Mid-peak, when demand for electricity is moderate. These periods are during the daytime, but not the busiest times of day.
  • On-peak, when demand is highest. The busiest times of day. Generally when people are cooking, using their computers and running heaters or air conditioners.

The chart below shows the price you pay for electricity at different times of the day.  To view previous rates, click here.  To learn more about understanding your bill, click here.


Distribution Charges

At Oakville Hydro, we purchase the electricity we deliver to customers at market prices and earns no margin on the sale of the commodity.  Oakville Hydro’s charges account for approximately 19% of the total bill for a typical residential customer.

The other charges on your bill are collected by Oakville Hydro on behalf of other electricity market participants, including generators, transmitters, retailers and regulators.
