The clock may fall back Sunday, but hydro prices are headed the other way.

Higher time-of-use prices take effect Nov. 1, and the cost of using electricity during peak hours will be a budget-zapping 17.5 cents kWh.

The Ontario Energy Board (OEB) estimates the average family of four that uses 800 kWh per month of electricity will pay an extra $4.42 per month or $53.04 a year based on the new prices.

The pricing is an attempt to discourage consumers from using electricity during peak hours.

“Through recent OEB consumer research, Ontarians have signalled a need for pricing that provides greater incentives to conserve,” the OEB said in a statement.

The cost of electricity is just one part of a customer’s bill, though.

The government has said it will remove the debt repayment charge from residential bills as of Jan. 1, a savings of about $70 a year.

At the same time, it intends to end the 10% discount it currently offers — the Ontario Clean Energy Benefit — which saves the average family about $180 a year based on 2014 bills.

Once all the adding and subtracting is completed, the typical Ontario family can expect to be out at least $170 more next year based on these changes.
