SRP Time-of-Use Price Plan™ (TOU)
The SRP TOU Price Plan offers the greatest savings opportunity of any of our time-of-day plans. Learn how you can save by shifting your energy use to off-peak hours.
A temporary price reduction for the summer.
Due to lower-than-expected natural gas and market power costs, SRP will temporarily lower prices by $0.0038 kWh during the May–October 2026 billing cycles.

This price plan is discontinued
This price plan is no longer available for new enrollments and will be discontinued after the November 2029 billing cycle.
If you're currently enrolled in this plan, you may continue to be on it until the November 2029 billing cycle. SRP will notify you at least 120 days before the plan ends, so you have time to choose a new plan. You can also switch your plan any time before then.
Why is my price plan being discontinued?
On Feb. 27, 2025, SRP’s publicly elected Board approved the retirement of select price plans. To learn more about these changes, visit srp.net/resprices.
How it works
At certain times of the day, many people and businesses in the Valley are using energy, which puts pressure on the power grid. The SRP TOU Price Plan offers price breaks for customers who can commit to shifting their energy use outside of those high-demand, or “on-peak,” hours.
This price plan is a good option for customers who are conscious of their energy use and who have a large home or pool.
Understanding on-peak hours
Once you understand how on-peak hours work, it’s easy to make the shift. All it takes is some planning and attention to your energy use.
During on-peak hours, you’ll want to avoid using major home appliances, such as your dishwasher, clothes washer or dryer.
You’ll pay less for energy all other hours, including weekends and on six observed holidays 
.
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.
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.
Why are energy prices higher in the summer?
Regardless of your price plan, energy costs change in the summer and winter in response to demand. In the hot summer months, demand for energy is high, which means higher generation costs and higher prices. In the winter months, demand for energy falls and prices do too.
