    Saving on solar and demand price plans

    Similar to our time-of-day price plans, our solar and demand price plans offer price breaks for customers who can shift their energy use to off-peak hours and keep their household demand for energy low by using appliances one at a time.

    • Customer Generation Plan — For customers who are able to maintain their demand at moderate levels. Save by actively tracking and managing your energy use and using most energy during off-peak hours.
    • Average Demand Plan — For customers who can shift energy use to off-peak hours but don’t want to worry about occasional spikes in demand.
    • Time-of-Use Export Plan — No monthly demand charge. Save by using energy you’ve generated and limiting your use of grid energy to off-peak hours.
    • Electric Vehicle Export Plan — No monthly demand charge. If you have rooftop solar and an electric vehicle, you can save by charging overnight during super off-peak hours.
    • Residential Demand Price Plan Pilot — The lowest residential prices we offer. Save by staggering the usage of your electrical appliances during on-peak hours and shifting large-appliance usage to off-peak hours as much as possible. No rooftop solar required.

    What is demand and why does it matter?

    To understand demand, it’s important to also know how energy, or consumption, works. Demand is the amount of power your home uses at any given point in time, measured in kilowatts (kW). Although related, energy measures how much power you use over a given period of time, measured in kilowatt-hours (kWh).

    SRP's demand charges are based on demand measured during 30-minute intervals during on-peak hours. Choosing the demand price plan above that best matches your lifestyle and needs is an important factor when it comes to saving money.

    For example, the Customer Generation Plan bills on the highest 30-minute on-peak interval during the month, while the Average Demand Plan averages the daily maximum demands over the month. To avoid high demand charges, stagger your use of large electrical appliances during on-peak periods and limit their use to off-peak hours as much as possible.

    Tips to minimize demand

    Pool pump icon

    Pool pump
    Install a timer for your pump. Run the pump just long enough to keep the water clean.

    Oven icon

    Oven
    Avoid using the oven during peak hours. Grill outside or use the microwave instead.

    Washing machine icon

    Washing machine
    Use your washer and dryer only during off-peak hours. Be sure to use cooler temperature settings.

    Water heater icon

    Water heater
    Install a timer for your water heater to keep it from running during on-peak hours.

    Electric vehicles icon

    Electric vehicles
    Charge only during off-peak hours.

    Air conditioner icon

    Air conditioner
    Precool your home before peak hours start to decrease demand during high-cost times.

    Delayed start button icon

    Delayed start button
    See if your appliances, like your dishwasher, have a delayed start feature. You can easily run them when peak hours end.

    Peak demand and solar

    To save on a demand plan, it’s important to avoid pulling energy from SRP’s grid during peak hours. Your house will pull power from the grid anytime your energy use exceeds what you’ve generated. During peak hours, grid energy is most expensive because that’s when demand is highest. To avoid pulling energy from the grid when rates are highest, limit your energy use during peak hours — use major electrical appliances either before or after instead.

    Benefits of battery storage

    Batteries store excess power for future use and give you greater control over how and when you’re using energy. Depending on your price plan and how your batteries are set up, it may be advantageous to pull energy from the grid during off-peak hours to cover your on-peak usage. For example, charging your batteries at night for use during the day.

    Ways to manage energy demand

    One of the best ways to manage energy demand is by installing a demand management system (DMS). A DMS is an innovative technology that lets you automate when major appliances run during on-peak hours to make sure they don't run at the same time. With a demand management system, you can:

    • Monitor and control your home's electric load.
    • Reduce peak demand costs and help reduce your electric bill.
    • Optimize when your home uses energy.
    • Add convenience with set-and-forget operation.
