Basic information about M-Power
The M-Power box makes it easy to see how much credit is remaining on your meter and it will alert you when your credit is getting low. The M-Power box tracks energy costs by the hour, day and month so you can see how much you are spending. You can also compare the cost for the current and previous month, which could help you use less energy and save money.
The credit remaining displayed in My Account or the M-Power Mobile App is not real-time and will update each night with the midnight meter read and each time you make a purchase. So, the credit remaining in My Account or the app is as of the midnight meter read or your last purchase, whichever was most recent. To see your credit remaining in real-time, check your M-Power box.
The M-Power Card you received with your starter kit will be used to connect your M-Power Box to your meter. This allows your M-Power Box to display real-time data from your meter. Your M-Power Card can also be used to look up your account data at any SRP PayCenter location.
Making a purchase
A credit or debit card purchase can be made online at SRPnet.com or by calling SRP at (602) 236-8888. Credit and debit card purchases are processed by a third party payment processor who charges a fee of $2. SRP does not collect any fees in connection with credit or debit card payments.
Credit card purchases may not be made through the app.
Payments can be made with your checking account by using eChex, SRP’s electronic check payment option. You can also make an eChex payment through the M-Power App, online at SRPnet.com, or by calling SRP at (602) 236-8888. If you have opted to have your checking information saved, you can also use eChex to make a purchase at any SRP PayCenter. Purchases will need to be ‘Authorized’ before credit is sent to the meter.
You can make a purchase with cash at any SRP PayCenter by entering your account number or by using your M-Power Card to access your account. Purchases will need to be ‘Authorized’ before credit is sent to the meter.
The safety statement is in place for you to ensure it is safe for power to be delivered to your meter. To avoid the risk of fire, please make sure any electric appliances, such as an electric stove, are turned off at the time power is delivered.
The M-Power program requires a $102.50 refundable deposit as well as an $11.50 plus tax refurbishment fee for the M-Power Box provided. SRP will also advance $30 of credit to your meter. A service establishment fee of $30 plus tax will be charged for customers starting new service. This fee does not apply for existing customers requesting to change to the M-Power program. A portion of any future purchases made for electricity will be applied towards any balance owing.
The $102.50 deposit applies to your account when you turn off service. In the event the M-Power Box is damaged, lost or not returned when the account is closed, the charge is $133 plus tax.
The Paydown balance is the current balance on your M-Power account. A percentage of each purchase made for electricity while on M-Power is applied to this balance until it is paid in full.
For customers with accumulated debt as of Oct. 1, SRP will automatically move this debt to a paydown balance. If included, you’ll be able to see your paydown balance in the M-Power app and on My Account.
- For customers with under $500 in accumulated debt, 35% of future purchases will go toward paying this balance off.
- For customers with a between $500 and $1,000 in accumulated debt, 50% of future purchases will go toward paying this balance off.
- For SRP M-Power customers with over $1,000 in accumulated debt, 75% of future purchases will go toward paying this balance off.
If you don’t want your debt moved to your paydown balance, make a purchase to cover this debt before Oct. 1.
The M-Power Box shows you the cost of the energy you are using in dollars and cents. You can view your cost for today, yesterday, this month and last month to help monitor and compare your usage. The M-Power box will display the days and credit remaining. You can also view your usage information at srpnet.com\MyAccount. You may be able to make your credit last longer by finding ways to conserve energy.
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 costs for SRP to meet this demand. This results in a higher cost for electricity in the summer.
Excessive Heat Warnings
Keeping you safe and in power during excessive heat is a priority for SRP. When the National Weather Service issues an Excessive Heat Warning, SRP may keep you in power even if you run out of credit on your meter. Please continue to make purchases during an Excessive Heat Warning to ensure there is no interruption in service when the heat warning ends.
Yes. Although the power may not go off during an Excessive Heat Warning, you should continue to make purchases to keep credit on the meter during this time. If any power is used after the credit on the meter runs out, the cost for this power will be seen on the ‘Accumulated Debit’ screen on the M-Power Box. Before the heat warning ends, a purchase should be made to cover any accumulated debt, as well as additional credit, to ensure there is no interruption in service.
Before the heat warning ends, a purchase must be made to cover any accumulated debt, as well as additional credit, to ensure there is no interruption in service. If you do not make a purchase greater than your accumulated debt amount, your power will be disconnected when the Excessive Heat Warning ends. If your power disconnects and you are unable to make a purchase, please call (602) 236-8888. We are available to assist you 24 hours a day, seven days a week.
Extension of credit
"Friendly Credit" allows your power to stay on if your meter runs out of credit late at night. The cost for any power used after the credit on the meter has run out can be seen on the ‘Accumulated Debt’ screen of your M-Power Box. A purchase should be made to cover any accumulated debt, as well as additional credit, to ensure there is no interruption in service.
Accumulated debt is any usage registered on your meter after your credit has run out and power remains on. Accumulated debt may occur during Friendly Credit hours, emergency credit, Excessive Heat Warnings and holidays. This amount can be found on your M-Power Box under the “Accumulated Debt” screen. A purchase should be made in an amount that will cover any accumulated debt, as well as additional credit, to ensure there is no interruption in service. When a purchase is made and then loaded to your meter, the amount of any accumulated debt will be subtracted from the value of the purchase that is loaded.
If you run out of credit, your meter will disconnect and you will need to make a purchase to restore power. If power remains on after credit runs out, your meter will track any usage and accumulate debt. The cost for any power used after credit on the meter has run out can be seen on the ‘Accumulated Debt’ screen of your M-Power Box. For more detail, see previous question: What is accumulated debt?

Deposits and termination of service
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.
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.
