Electricity Rates & Options

If you’re a residential or small business customer, you can choose to switch between Tiered, Time-of-Use (TOU) and Ultra-Low Overnight (ULO) prices. 

To switch pricing plan, you will need to notify Oakville Hydro either by completing an election form or by contacting us at 905-825-9400 (Monday to Friday, 8:30 AM to 4:30 PM). 

You may not wish to change your electricity pricing plan. In that case, no action is required.

Ontario Electricity Rebate 
On November 1, 2019, the Ontario government launched the Ontario Electricity Rebate (OER), which started being applied to bills for eligible residential consumers, farms and small businesses. As of November 1, 2026, the OER will be 15.7% and is a pre-tax credit that appears at the bottom of electricity bills.

If you have a residential or small business (general service less than 50 kW) account with Oakville Hydro, you do not need to do anything. You will automatically receive the OER. Learn more and see if your business qualifies at this link.

Distribution Charges - January 1 to December 31, 2026
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 20% 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.
