Average Demand Price Plan for solar customers

How it works
You’ve got potential to save on the Average Demand Price Plan if you can limit your household demand for energy during on-peak hours.
To do this, make sure that major appliances, such as the dishwasher, clothes washer or dryer, don't run at the same time and never during on-peak hours.
On-peak hours are weekdays from 2–8 p.m. May through October and weekdays from 5–9 a.m. and 5–9 p.m. November through April. All other times, including weekends and six holidays 
, are off-peak.
This plan may be right for you if:
- You have routine on-peak demand of 10 kilowatts (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 don’t want to worry about unexpected spikes in demand.
Did you Know?
As a not-for-profit utility, SRP has the lowest electricity prices of any major utility in the state and delivers among the most reliable power of any large utility in the nation, according to eia.gov (Opens in a new tab) .
Pricing
Energy charge — Energy is priced per kilowatt-hour (kWh) and your monthly energy charges are based on the amount of energy used at on- and off-peak times during your billing cycle. Off-peak times (when demand is low) offer the lowest prices and vary by time of day and year.
Demand charge — The demand charge is based on 30-minute intervals during on-peak hours when your home uses the most electricity and that electricity is most expensive.

Seasonal rate changes — When a seasonal rate change occurs — such as the transition from winter rates to summer rates — all energy usage and monthly demand charges on your bill are calculated using the rate in effect on your meter read date. For example, if your meter is read on May 14, all usage and demand charges included on that bill are billed at the summer rate, even though some of the usage occurred in April.
Monthly service charge (MSC) — Your MSC helps cover the costs of customer service, billing and your connection to the grid.
Tier 1
If you're in an apartment, condominium or townhome, your MSC will likely be $20.
Tier 2
If you're in an average single-family home, your MSC will likely be $30.
Tier 3
If you're in a larger-than-average single-family home with high power usage (i.e., you have multiple pool pumps, EV charging stations and/or multiple AC units), your MSC will likely be $40.
