Solar Price Plans FAQ

Find answers to frequently asked questions about SRP's price plan options for customers who produce some of their own energy with rooftop solar or other distributed generation technologies.

The right price plan will depend on a number of factors such as your solar system, energy usage, devices and appliances, preferences, lifestyle and more. See our guidelines below to help you decide.

Price plan

May be right for you if:

Time-of-Use Export

  • You prefer a plan with no demand charge and want a simpler approach to energy management.
  • You have a fully electric home and use your air conditioner or heater frequently, especially during on-peak hours.
  • You have a tankless electric water heater.

 

Electric Vehicle Export

  • You prefer a plan with no demand charge and want a simpler approach to energy management.
  • You have a fully electric home and use your air conditioner or heater frequently, especially during on-peak hours.
  • You have a tankless electric water heater.
  • You have an electric vehicle and are able to charge during super off-peak hours — 11 p.m. to 5 a.m. daily.

 

Average Demand

  • 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 one-off spikes in demand.

 

Customer Generation
  • You want low per kWh energy prices for energy supplied by SRP.
  • You want the potential to save by managing your energy demand.
  • Your demand is typically consistent.
  • Any of your unexpected spikes in demand can be mitigated with Demand Assurance.

Two export price plans are available: Time-of-Use Export and Electric Vehicle Export.

On an export price plan, you pay only for the energy from the grid you use, and any excess energy you generate is credited at a fixed price — 2.81 cents per kWh — and subtracted from your bill.

You can save the most when using energy supplied directly from your rooftop solar system. Keep in mind that cloud cover, shade and the time of year all impact energy production.

When using energy supplied by SRP, you can save the most when you limit your energy use during high-priced on-peak hours, when energy is more expensive to produce, and shift usage to lower-priced off-peak hours.

On-peak hours are from 2–8 p.m. between May and October and from 5–9 a.m. and 5–9 p.m. between November and April.

Two demand-based solar price plans are available: Customer Generation and Average Demand.

Both price plans have the lowest per kWh energy prices of any SRP residential price plan. They also offer the potential to save if you use energy in a way that minimizes your household's demand for electricity during on-peak hours when energy is more expensive to produce. Managing your peak energy demand, included on your monthly bill as a demand charge, can help SRP reduce costs and pass savings back to you.

See our tips on understanding demand and reducing your peak demand.

The best way to save money on a demand-based price 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 2-8 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.

* New Year's Day (observed), Memorial Day, Independence Day (observed), Labor Day, Thanksgiving Day and Christmas Day (observed)

Demand Assurance is available with the Customer Generation Price Plan.

It is not available with the Average Demand, Time-of-Use Export or Electric Vehicle Export price plans.

A demand management system can help you save on both the Customer Generation and the Average Demand price plans. Because both are demand-based price plans, you will see higher bill savings if you consistently keep daily peak demands low.

SRP is offering a $250 rebate on demand management systems. Only SRP's Preferred Solar Installers can install a demand management system in order for it to be eligible for the rebate. We also offer tips to reduce peak demand.

Yes, a battery storage system can be used on any of the four solar price plans. SRP is providing incentives for batteries so we can research their potential benefits and effect on the grid.

It is unclear at this time if SRP customers can save money using batteries. We're providing incentives for batteries so we can research to what extent residential distributed batteries reduce SRP's costs and how we can pass any realized savings along to battery customers.
