SRP M-Power^® prepaid price plan

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. You can also view your usage information at srp.net/myaccount. You may be able to make your credit last longer by finding ways to conserve energy.

1. Be sure you are reducing energy use. Check out energy-saving rebates.
2. See if another price plan would better fit your household and lifestyle.

If you want to switch to a different plan, call (602) 236-8888(602) 236-8888.

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 our Economy Price Plan (EPP) monthly discount. For EPP 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.

The most convenient way to return your in-home display box is by U.S. mail. Simply place the display in its original shipping box and use the postage-paid label already attached to the bottom to send it back to SRP. If you don’t have the original box anymore, call us at (602) 236-8888(602) 236-8888 and we will mail you a postage-paid envelope. 

Your SRP M-Power in-home display can also be returned to any return station (listed below). Using a return station is easy:

• Place the SRP M-Power box in the envelope provided at the station.
• Seal the envelope.
• Remove the confirmation tag from the envelope to keep for your records.
