SRP M-Power® prepaid price plan
How it works
SRP M-Power customers keep it simple — no monthly energy bills, no surprises. Pay in advance for just a few days or a few months. Using the free SRP M-Power app or SRP My Account™ allows you to track how much energy you've used and how much you have left. The average SRP M-Power customer saves 12% on energy costs compared to customers who receive monthly bills on other SRP plans.

FAQ
This year SRP will transition to new technology, making SRP M-Power fully digital. In-home display boxes will be deactivated, and you will manage your power usage entirely through the SRP M-Power® app or SRP My Account™.
If you are already using the app to manage your account, you will not be affected. You will be notified via an email or letter when your account is transitioning. If you have questions, call us at (602) 236-8888.
The SRP M-Power app shows you the cost of the energy you are using in dollars and cents. You can view your costs for the last 30 days. The SRP M-Power app will display the days and credit remaining.

The kilowatt-hour (kWh) or unit cost of energy is different in winter and summer on every price plan. The price you pay reflects this seasonal change in cost according to your price plan.
During winter months, customer usage and the cost to generate electricity is lower resulting in lower pricing. In summer months, demand for electricity is much higher as is the associated cost for SRP to meet this demand. This results in a higher cost for electricity in the summer.
Billing months
A paydown balance is an amount owed to SRP. A percentage of each purchase made while on SRP M-Power is applied to this balance until it is paid in full. If the total amount owed to SRP is:
- Less than $500, 35% of future purchases will go toward the paydown balance.
- Between $500 and $1,000, 50% of future purchases will go toward the paydown balance.
- Over $1,000, 70% of future purchases will go toward the paydown balance unless you receive the SRP Income-Qualified Discount™ (IQD) monthly discount. For IQD customers, the paydown percentage will be capped at 50%.
If you have a balance of over $500 that falls below $500 as you make payments, your paydown percentage will drop to 35%. If you would like to lower your paydown balance faster, you can make payments by giving us a call. Lowering your balance can allow more of your purchases to go toward your meter.
The deposit you paid, including any unpaid interest earned, will be applied to your final bill. If applying the deposit results in a credit balance on your account, a refund check for the balance will be sent to you at the mailing address you provided when service is turned off.
Interest on your deposit is earned at the average certificate of deposit (CD) rate paid by local financial institutions. SRP will credit the interest to your account in January when the deposit has been held for at least six consecutive months. The interest rate is reviewed annually and adjusted as needed. View the SRP residential credit policy.
SRP will remove the credit from your account at the time of your turnoff. Any credit or accumulated debt will be adjusted on your final bill.
We are no longer requiring or accepting returned SRP M-Power boxes. If you have an SRP M-Power box in need of disposal, please follow your local electronic waste disposal program's guidelines.
You can lower your SRP bill by shifting your energy use to off-peak hours through time-of-day plans such as the Time-of-Use or the SRP EZ-3 Price Plan™, using appliances like dishwashers and pool pumps outside of peak periods and precooling your home before higher-rate times. Customers can also take advantage of a free SRP Home Energy Assessment™ with tips and products to save energy, plus SRP Budget Billing™ to make payments more predictable. Customers who meet income guidelines can enroll in the SRP Income-Qualified Discount™ for monthly discounts or request payment plans if needed.

Living in the desert comes with higher summer bills compared to winter, but with SRP Budget Billing, you're able to pay a balanced and consistent rate each month. Learn more here.
