Learn the impacts on demand of running appliances simultaneously
Customers on SRP's Customer Generation Price Plan and Residential Demand Price Plan Pilot pay a charge based on their on-peak demand each billing cycle. Demand is the amount of power needed to supply every electrical device running in your home at a specific point in time.
As more appliances in your home run simultaneously, your demand for power increases. This is why it's important, under the Customer Generation Price Plan and Residential Demand Price Plan Pilot, to limit the simultaneous use of appliances during on-peak hours.
Summer and summer-peak on-peak hours are from 1-8 p.m. May through October.
Winter on-peak hours are from 5-9 a.m. and 5-9 p.m. November through April.
Select the summer or winter button below to see an example of what a single-family household's seasonal peak demand might look like during on-peak hours. While the energy required to run appliances can vary by brand and model, you can modify your own demand profile below by turning the appliances on and off and seeing the estimated collective impact on the monthly demand charge.
