Average Demand Price Plan

This plan is one of several price plan options for customers who produce some of their own energy with rooftop solar or other distributed generation technologies. It includes a monthly demand charge.

The best way to save money on this plan is to:

  • Shift energy use from on-peak to off-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*, are off-peak.
  • Manage energy use in your home so major appliances that demand large amounts of electricity don't run at the same time during on-peak hours.

Is this plan right for me?

The Average Demand plan might 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 prefer the peace of mind of not having to worry about unexpected spikes in demand.

Customers who prefer a demand based rate and are willing to actively manage their energy use through technology, lifestyle changes or other methods may find the Customer Generation Price Plan more beneficial.

Understanding the bill

This bill for this price plan has three components.

  • Energy charge: This reflects the amount of power you consume over time.

    The total amount of energy you use over time is measured in kilowatt-hours (kWh). The price of energy used during the billing cycle varies based on whether electricity is used during on- or off-peak hours.

  • Average demand charge: This plans offer the potential to save if you use energy in a way that minimizes your household's demand for energy during on-peak hours when electricity is more expensive to produce. Managing your energy demand can help SRP reduce costs and pass savings back to you.
    Understanding demand

    What is demand?
    Demand is the amount of power your home needs at any given point in time. By limiting simultaneous use of appliances during on-peak hours, you can keep the demand charge lower. Your solar generation may help to offset some of your demand for energy from SRP during some on-peak hours, but because solar production can be affected by external conditions such as clouds, relying on it to lower your demand may be risky.

    How is the average demand charge calculated?
    The demand charge for each billing cycle is calculated per kilowatt (kW). The average demand charge is based on the average of the daily on-peak maximum demands for the billing month. A single day's on-peak maximum is based on a 30-minute interval during on-peak hours when your home used the maximum or peak amount of electricity. These 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.)

    On-peak demand charges (per kW)
    (May, June, Sept., Oct.)
    $8.13 $19.29 $21.94
  • 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.

    A portion of this plan's monthly service charge is based on the size of your home's Service Entrance Section (SES) – the electrical panel where power enters the home. Most homes within SRP's service territory will be billed $32.44 per month. Some very large homes with an SES larger than 200 amps will pay $45.44 per month.
