Ontario Electricity Rebate
The Ontario Electricity Rebate (OER) is a provincially funded credit that reduces the pre-HST portion of eligible electricity bills by 23.5 per cent. If your business qualifies, the rebate will appear as a separate line item labelled “Ontario Electricity Rebate” on your monthly Hydro Ottawa bill.
If you're a business customer, the rebate is automatically applied each month as long as:
Your demand for electricity is 50 kilowatts (kW) or less
Your annual electricity usage is 250,000 kilowatt-hours (kWh) or less
