Electricity Rates and Charges

Customer Choice 

If you’re a residential or small business customer that pays Time-of-Use (TOU) electricity prices, you can choose to switch to Tiered prices beginning November 1, 2020.

To switch from TOU to Tiered prices, you will need to notify Oakville Hydro either by filling out our online form (click here), completing an election form (click here) or by contacting us at 905-825-9400 (Monday to Friday, 8:30 a.m. to 4:30 p.m.). 

You may wish to continue paying TOU prices for your electricity. In that case, no action is required.

Ontario Electricity Rebate 

On November 1, 2019, the Ontario Electricity Rebate (OER) started being applied to bills for most residential consumers, farms and many small businesses. Effective November 1, 2021 the Ontario government’s Ontario Electricity Rebate (OER) will be changed to 17.0% (from 18.9%).The OER is a pre-tax credit that appears at the bottom of electricity bills. For a typical residential customer living in Oakville who uses 700 kWh of electricity per month with TOU pricing, the OER would decrease bills by approximately $20.30 per month. For a typical residential customer living in Oakville who uses 700 kWh of electricity per month with Tiered pricing, the OER would decrease bills by approximately $19.62 each month.
It will continue to appear on your hydro bill as a single item. To learn more about the Ontario Electricity Rebate, visit the Ontario Energy Board website at this link.
