New electricity prices and periods take effect May 1

New electricity prices and periods take effect May 1

The Ontario Energy Board (OEB) announced new electricity prices and Time-of-use periods for households and small businesses, effective May 1, 2021, under the Regulated Price Plan (RPP). 

The Government is also decreasing the Ontario Electricity Rebate (OER) from 21.2 per cent to 18.9 per cent, effective May 1, 2021. The Government’s intention is that, for residential and small business customers, the reduction in the electricity price will be offset by the change in the OER. The OER is a total pre-tax credit that appears at the bottom of electricity bills. As a result of lower RPP prices and the reduced OER, typical residential customer bills will be held stable. The typical residential RPP customer uses 700 kWh of electricity per month.

New RPP prices starting May 1, 2021 

The new RPP TOU prices set by the OEB for May 1, 2021 are shown in the table below. The table also shows the hours during which those prices apply:
