Time-of-Use Pricing

If you have a Smart Meter installed, your utility has the option of charging different rates throughout the day. These rates are divided into three separate bands known as off-peak, mid-peak and on-peak. The different bands and rates are shown below.

From To Summer Rate Winter Rate Comparison of Time-of-Use Rates 7:00 AM 8:00 AM mid-peak rate 9.2 cents/kWh on-peak rate 10.8 cents/kWh 8:00 AM 9:00 AM 9:00 AM 10:00 AM 10:00 AM 11:00 AM 11:00 AM 12:00 PM on-peak rate 10.8 cents/kWh mid-peak rate 9.2 cents/kWh 12:00 PM 1:00 PM 1:00 PM 2:00 PM 2:00 PM 3:00 PM 3:00 PM 4:00 PM 4:00 PM 5:00 PM 5:00 PM 6:00 PM mid-peak rate 9.2 cents/kWh on-peak rate 10.8 cents/kWh Note Off peak rates are charged on weekends and holidays. The rates shown to the left apply Monday to Friday. 6:00 PM 7:00 PM 7:00 PM 8:00 PM off-peak rate 6.2 cents/kWh off-peak rate 6.2 cents/kWh 8:00 PM 9:00 PM 9:00 PM 10:00 PM 10:00 PM 11:00 PM Based on a small sample of 27 households, we calculate that, on average, time-of-use consumption typically breaks down as follows: 11:00 PM Midnight Midnight 1:00 AM 1:00 AM 2:00 AM Off-peak: 55.2% Mid-peak: 17.2% On-peak: 27.2% 2:00 AM 3:00 AM 3:00 AM 4:00 AM 4:00 AM 5:00 AM This results in a blended rate of 7.74 cents/kWh.

Normal Meter Pricing

If you do not have a Smart-Meter or if your hydro utility is not utilizing time-of-use billing, you are charged the same rate regardless of when you consume your electricity. The RPP rate has two price tiers. The price you pay depends on how much electricity you use. In the summer, the higher price is used when you consume more than 600kWh of hydro in a given month. In the winter months, the higher electricity price is charged for consumption above 1,000 kWh.

First 1000 Kilowatt Hours per month: 7.1 cents/kWh Above 1000 kWh: 8.3 cents/kWh
