The M-Power in-home display shows the 'Cost Yesterday' and 'Cost Last Month,' helping you monitor your energy use in dollars and cents. You may also use the 'Present electric demand' to see the amount of energy you are currently using.

The kilowatt-hour (kWh) or unit cost of energy is different in winter and summer regardless of your price plan. The price you pay rises and falls with the demand for electricity.

During the coolest months, customer usage, generation costs and the price you pay are lowest. During the hottest months, customer usage skyrockets and generation costs to meet peak demand are highest.

Those customers switching rate plans, but not establishing service at a new address, are not subject to the turn-on fee.

The M-Power in-home display plugs into an outlet and is used to load your smart card purchase to the meter and view your energy usage. You can track energy costs by the hour, day and month. You can also track costs for the current month and previous months to help you use less energy and save money. The display makes it easy to see how much credit is remaining on your meter. Based on your current usage, you'll even receive an alert when only a few days of energy remain.

When your service is turned on, you may pay over time the refundable $102.50 equipment deposit and $11.50 refurbishment fee for the M-Power in-home display. The $102.50 deposit applies to your account when you turn off service. In the event the in-home display is damaged, lost or not returned when the account is closed, the charge is $133 plus tax. There is no cost for the smart cards.

The $102.50 equipment 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.

Yes. After the payment has been made, contact SRP to verify that it has been received*. Once SRP has verified the payment, you can visit an SRP PayCenter and insert $1 to load the eChex or credit or debit card payment onto the smart card.

You can also link your active checking account to your M-Power account so that you no longer need cash to make a purchase at Paycenters. Just contact SRP at (602) 236-8888 to set up eChex by linking your bank account information. Once it is set up, you can select the eChex option at any PayCenter to purchase power.

*Please note that there is a fee charged by a third party for credit or debit card payments. Please allow one business day for payment processing.

If you run out of credit, your meter will disconnect and you will need to make a purchase to restore power. If you run out of credit between 8 p.m. and 8 a.m., your meter will stay connected and enter the Friendly Credit hours mode. You must buy power prior to 8 a.m. the next day to avoid a power interruption. The next time you load your smart card to your in-home display, the cost of any electricity used during Friendly Credit hours will be subtracted from your purchase amount.

SRP extends $30 credit to get you started. This amount, along with the equipment deposit, if applicable, and any applicable fees and/or transferred balances are paid down each time you make a purchase.

*$1,000 is the maximum back balance that can be carried over from a credit account.

A customer meeting income guidelines may qualify for the EPP. Customers on the medical discount/rider are not eligible for the M-Power program.

SRP will remove the credit from your meter at the time of your turn off. Any credit or accumulated debt will be adjusted on your final bill.
