    How it works

    You’ve got potential to save on the Average Demand Price Plan if you can limit your household demand for energy during on-peak hours.

    To do this, make sure that major appliances, such as the dishwasher, clothes washer or dryer, don't run at the same time and never during on-peak hours.

    On-peak hours are weekdays from 2–8 p.m. May through October and weekdays from 5–9 a.m. and 5–9 p.m. November through April. All other times, including weekends and six holidays Open tooltip to learn more., are off-peak.

    This plan may be right for you if:

    • You have routine on-peak demand of 10 kW or higher.
    • You have big variations in your demand – meaning, for example, you typically have a demand of 5 kW, but once or twice a month your demand reaches 10 kW or more.
    • You don’t want to worry about unexpected spikes in demand.

    On this plan, your bill is calculated based on three charges:

    1. Energy charge – The amount of power you consume over time. It’s measured in kilowatt-hours (kWh), and the price varies based on whether electricity is used during on- or off-peak hours.
    2. Monthly service charge – This helps cover the costs of grid access and maintenance. Most customers on this price plan will pay a monthly service charge of $32.44.
    3. Average demand charge – Measured in kilowatts (kW), demand is the amount of power your home uses at any one time. The average demand charge is based on the average of your daily on-peak maximum demand for the billing month.

    A single day's on-peak maximum is based on the 30-minute interval during on-peak hours when your home used the most electricity.

    Intervals are measured between the hour and half-hour during on-peak hours (for example, between 2 and 2:30 p.m. and 2:30 p.m. and 3 p.m., etc.)
