Customer Generation Price Plan

The Customer Generation Price Plan is the price plan for residential customers who choose to produce some of their own electricity using rooftop solar or other means.

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 5-9 a.m. and 5-9 p.m. November through April and weekdays from 1-8 p.m. May through October. 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.

The Customer Generation Price Plan has the same on-peak hours as SRP's Time-of-Use (TOU) price plan, but is different in that it offers two ways to control your bill:

  • The energy charge on this plan is about half the rate of the TOU plan. It's also the lowest of any SRP residential price plan. Energy is 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. The Customer Generation Price Plan features the lowest residential energy prices offered by any SRP price plan.

    A bar chart comparing off-peak and on-peak prices between the Customer Generation Price Plan and the Time of Use Price Plan. Off-peak prices for the Customer Generation Price Plan are 3.9 cents per kilowatt hour from November to April, 3.71 cents from May to June and September to October and 4.23 cents in July and August. On-peak prices are 4.3 cents from November to April, 4.86 cents in May, June, September and October and 6.33 cents in July and August. On the Time-of-Use plan, which has the same off-peak and on-peak hours, prices are as follows during off-peak hours: 7.11 per kilowatt hour from November to April, 7.38 cents in May, June, September and October, and 7.41 cents in July and Augus. On-peak Time of Use prices are 10.2 cents per kilowatt hour from November to April, 19.57 cents in May, June, September and October and 22.26 cents in July and August.

  • There is a per-kilowatt demand charge, based upon your usage of the energy supplied by SRP. 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.

    The demand charge for each billing cycle is calculated per kilowatt (kW). It is based on the 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 1 and 1:30 p.m. and 1:30 p.m. and 2 p.m., etc.)

    On-peak hours are weekdays 5–9 a.m. and 5–9 p.m. from November through April and weekdays from 1–8 p.m. May through September. All other times, including weekends and six holidays are off-peak and the demand charge does not apply.

    On-peak demand charges (per kW)
    First 3 kW Next 7 kW All add'l KW
    WINTER (Nov.-April) $3.55 $5.68 $9.74
    SUMMER (May-June and Sept.-Oct.) $8.03 $14.63 $27.77
    SUMMER PEAK (July-Aug.) $9.59 $17.82 $34.19

  • The monthly service charge, which helps cover the costs of grid access and maintenance, is $32.44 on this plan for most residential customers. It is $20 on TOU.

    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.

    The service charge is higher on this plan than on TOU because TOU customers pay a higher energy charge, and grid costs are partially collected through those rates.
