SRP Business Time-of-Use Price Plan (TOU)
How it works
On the business TOU (E-32) price plan, electricity is priced at three different levels depending on the time of day — on-peak (5-10 p.m.), shoulder (3-5 p.m. & 10 p.m-8 a.m.) and off-peak (8 a.m.-3 p.m.) pricing periods.
The key to saving money on this plan is to limit usage during the higher-priced on-peak hours and instead shift usage to lower-priced off-peak and shoulder hours.
If you’re already doing this, switching to this SRP commercial price plan could maximize your energy savings.
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
In addition to per-kilowatt-hour charges, you will also see demand charges and a service charge on your bill.
Here’s a breakdown of the charges per season:
- Summer on-peak demand charge: $5.05
- Summer Peak on-peak demand charge: $6.75
- Winter on-peak demand charge: $4.45
- Summer, summer-peak and winter maximum of shoulder and off-peak demand charge: $1.02
- Monthly service charge: $15.16 plus meter charge (CT/PT $33.78 or demand $13.67)
- Weekend hours in the Summer, Summer Peak and Winter do not have on-peak: 5-10 p.m. are instead shoulder-peak.
One thing to note: Demand charges apply to all kW greater than 5 kW for the highest 30-minute demand during the on-peak period, and the combined shoulder-peak and off-peak periods.

How is this plan different from the General Service Price Plan?
The biggest difference is that the TOU plan is designed for businesses who can be more flexible in their operating hours vs. the General Service plan that encourages stability in energy use.
