Electricity Charge

This is the cost of the electricity supplied to you during a billing period and is the only part of your bill that is subject to competition.

Small business customers with a demand of less than 50 kW have the option of buying their electricity through the Regulated Price Plan (RPP) at a regulated price per kilowatt hour (kWh) or from a retailer. You are automatically part of the RPP unless you purchase your electricity from an electricity retailer.

The Ontario Energy Board (OEB) sets the RPP prices based on its forecast of the cost to supply households and small Businesses over the next 12 months. In addition to providing stable and predictable electricity pricing, these prices are designed to recover the payments made to the electricity generators that produce power. Hydro Ottawa, like other electricity utilities in Ontario, is not allowed to make a profit on the electricity we buy for our customers.

RPP prices are reviewed and adjusted twice a year, once in the summer (May 1) and once in the winter (November 1). If you leave the RPP by signing a retail contract or moving outside the province, you will either receive a credit or will need to pay a charge based on the difference.

Time-of-Use prices are designed to reflect the cost of electricity at different times of the day. There are three Time-of-Use periods – on-peak (highest price), mid-peak (mid-price) and off-peak (lowest price). These periods vary depending on whether it’s summer or winter. Like cell phone plans, prices are lower in the evenings, on weekends and on holidays. This encourages households and small businesses to use electricity during lower-cost time periods. In turn, this can ease the pressure on the provincial power system during high or peak demand periods. Reducing the energy required during peak demand period can also benefit the environment.

The RPP rate also includes the Global Adjustment, which reflects the difference between the market price of electricity and the regulated or contract prices that are paid to generators for the electricity they produce. For customers who purchase their electricity from a retailer, the Global Adjustment is a separate line item on their bill.
