    How it works  

    The Residential Demand Price Plan offers price breaks for customers who can be conscious of when they use energy and how much energy they’re using at one time.  

    To save on this plan, you’ll want to stagger the use of major appliances during on-peak hours. Putting appliances on a timer or an automated schedule can help.

    You’ll pay less for energy all other hours, including weekends and on six observed holidays Open tooltip to learn more..

    Understanding demand

    With proper on-peak demand management, the Residential Demand Price Plan allows you to cut monthly energy costs. Billed demand has a unique and controllable pricing structure.

    You can think of demand like a speedometer on a car. Using multiple appliances at once is the equivalent of driving fast; it uses more power at one time. On this plan, the goal is to drive at a slow and steady pace. You can do that by spreading out your energy use — staggering the use of major appliances — during on-peak hours.

    Monthly demand charge

    During on-peak hours, your household demand is measured in 30-minute intervals on the hour and every half-hour — from 2–2:30 p.m. and 2:30–3 p.m., for example.

    A monthly demand charge is calculated per-kilowatt (kW), based on the interval in which your home uses the most electricity during on-peak hours.


    Energy use is measured in kilowatt-hours (kWh). Your monthly energy costs reflect how many kWh of energy your household has used during the billing cycle. During on-peak hours, energy costs more per kWh. During off-peak hours, energy costs less per kWh.

    The Residential Demand Price Plan Pilot features the lowest residential energy prices offered by any SRP price plan, but you do have to manage your demand usage during on-peak hours.

    Why are energy prices higher in the summer? 

    Regardless of your price plan, energy prices are higher in summer months. That’s because demand for energy is higher in the summer. In the winter months, demand for energy falls – and prices do too. 

    Monthly service charge 

    This plan includes a monthly service charge that helps cover the costs of grid access and maintenance. For most residential customers, the charge is $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.

    Residential Demand vs. Time-of-Use (TOU) – What’s the difference?

    Both the Residential Demand and TOU price plans both offer price breaks for shifting your energy use to off-peak hours, but there are some key differences.  

    • Energy pricing on this Residential Demand Plan is about half the rate of the TOU plan.  

    • This Residential Demand Price Plan offers a cost incentive for keeping your household on-peak demand low by providing tiered kW pricing. 

    • On this plan, the monthly service charge for most residential customers is $32.44. It’s $20 on TOU. 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.
