SRP bill payment methods and where to send your money

Salt River Project (SRP) is Arizona's largest electric utility, serving the Phoenix metro area and surrounding regions. You can pay your SRP bill through their website, mobile app, by phone, by mail, or in person at payment centers. Each method has different timing and fee structures — some are free, and some charge a transaction fee depending on how you pay.

SRP does not require you to set up an account to make a one-time payment, though having an online account makes it easier to track your balance and due date. The bill itself shows your account number, current balance, and due date. Payment is due by 5 p.m. on the due date to avoid a late fee.

Key Takeaways

  • SRP's website and mobile app are free ways to pay, and both let you schedule payments in advance or pay when ready.
  • Phone payments through SRP's automated system are free, but paying through a third-party payment processor may charge a fee.
  • Mail payments take 7 to 10 business days to reach SRP, so send them well before your due date to avoid late fees.
  • In-person payments at SRP offices, authorized retailers, and some banks are processed the same day and carry no fee.
  • Late payments trigger a reconnection fee and may result in service disconnection if the account falls 30 days past due.

Paying online through SRP's website or app

The fastest and most common way to pay is through SRP's website at srpnet.com or their mobile app, available on iOS and Android. Both let you log in with your account number and password, or create an account if you do not have one yet. You can pay when ready or schedule a payment for a future date — useful if you want to time the payment with your paycheck.

Online and app payments are free and typically post to your account within one business day. You can set up a one-time payment or enroll in autopay, where SRP withdraws the full bill amount on a date you choose each month. Autopay removes the risk of forgetting a due date, though you should still review your bill each month to catch billing errors.

Paying by phone

SRP's automated phone system lets you pay 24 hours a day by calling 602-371-6000. You will need your account number and a debit card or bank account information. The automated system is free to use and processes payments when ready. If you prefer to speak with a representative, you can call during business hours (Monday through Friday, 7 a.m. to 6 p.m., Saturday 8 a.m. to 5 p.m. Arizona time), though this does not change the payment method or fee structure.

Some third-party payment processors also accept SRP payments over the phone, but these services often charge a convenience fee — typically 1 to 3 percent of your bill. SRP's own phone line does not charge this fee, so calling SRP directly is the cheaper option if you want to pay by phone.

Mailing a check or money order

You can mail a check or money order to the address printed on your bill. SRP's mailing address is typically listed in the "Pay Your Bill" section. Mail payments take 7 to 10 business days to arrive and be processed, so send your payment at least two weeks before the due date to may support it arrives on time. Late fees explore if payment is not received by 5 p.m. on the due date, regardless of when you mailed it.

Include your account number on the check or money order so SRP can match it to your account. If you lose your bill, you can find your account number on any previous bill, in your online account, or by calling SRP customer service at 602-371-6000.

Paying in person at SRP offices and authorized locations

SRP operates payment centers in the Phoenix area where you can pay in cash, check, or debit card. Payments made in person are processed the same day and carry no fee. SRP's main payment office is located at 1500 N. Mill Ave., Tempe, AZ 85281, and several branch offices are open during business hours. You can find the full list of locations and hours on srpnet.com.

Many authorized retailers and banks also accept SRP payments. These include some grocery stores, pharmacies, and financial institutions in the Phoenix area. Call 602-371-6000 or check srpnet.com to find a retailer near you. In-person payments at these locations are also processed the same day and typically carry no fee, though some retailers may charge a small transaction fee — ask before you pay.

Understanding late fees and reconnection charges

If your payment is not received by 5 p.m. on the due date, SRP adds a late fee to your account. The late fee amount varies but is typically a percentage of your bill or a flat fee — check your bill or account for the exact amount. A reconnection fee also applies if your service is disconnected due to non-payment and you later pay the balance.

Accounts that fall 30 days past due are subject to disconnection. SRP typically sends a disconnection notice before shutting off service, giving you time to pay or contact them about a payment plan. If your service is disconnected, you must pay the full past-due balance plus the reconnection fee to restore power. Contact SRP at 602-371-6000 if you are having trouble paying your bill — they offer payment plans and hardship programs for customers facing financial difficulty.

Autopay and scheduled payments

Setting up autopay through SRP's website or app removes the need to remember your due date each month. You choose the payment date, and SRP automatically withdraws the full bill amount from your bank account or debit card on that date. Autopay is free and can be canceled anytime if your circumstances change.

If you do not want full autopay but want to avoid late payments, you can schedule individual payments in advance through the website or app. This gives you control over the exact payment date and amount while still ensuring payment arrives on time. Both options are free and take effect within one business day.
