Rocky Mountain Power's bill pay options and how to use them

Rocky Mountain Power serves parts of Utah, Wyoming, and Idaho. You can pay your bill online through their website, by phone, by mail, or in person at a payment center. The online method is the fastest — your payment posts the same day if you pay before 5 p.m. Mountain Time on a business day. Phone and mail payments take longer, usually three to five business days to show on your account.

You do not need to create an account to make a one-time payment, but having one makes it easier to see your balance, set up automatic payments, and track payment history. The account is free and takes about five minutes to set up.

Key Takeaways

  • Online payments through Rocky Mountain Power's website or mobile app post the same business day if submitted before 5 p.m. Mountain Time.
  • Phone payments go through an automated system or a representative and typically take three to five business days to process.
  • Mail payments should be sent to the address on your bill and take five to seven business days from the time Rocky Mountain Power receives them.
  • Automatic payments withdraw money on a date you choose each month and eliminate the risk of a late payment.
  • You can pay without an account using your account number and ZIP code, but an account lets you see your balance and payment history anytime.

Paying online through the Rocky Mountain Power website

Go to rockymountainpower.net and select "Pay My Bill" from the homepage. You will see two options: pay as a guest or sign into your account. If you are paying as a guest, enter your account number (found on your bill) and ZIP code. The system will pull up your current balance and let you choose how much to pay.

Enter your payment method — debit card, credit card, or bank account. If you use a bank account, you will need your routing number and account number. Credit and debit card payments process when ready. Bank account payments take one to two business days. Once you confirm the payment, you will receive a confirmation number. Save or print it for your records.

If you create an account, you can save your payment method so you do not have to enter it each time. You can also set up automatic payments, view your billing history, and see your current balance without logging in each time.

Paying by phone

Call Rocky Mountain Power's automated payment line at 1-888-221-7070. You will need your account number and a payment method ready. The system will ask you to enter your account number using your phone keypad, then guide you through selecting your payment amount and method. The entire process takes about five minutes.

If you prefer to speak with a representative, you can call the same number and select the option to speak with someone. Representatives are available Monday through Friday, 7 a.m. to 7 p.m. Mountain Time. They can answer questions about your bill or account while processing your payment. Phone payments typically post within three to five business days.

Paying by mail

Write a check or money order payable to Rocky Mountain Power. Include your account number on the check. Mail it to the address printed on your bill — this address changes depending on which region you are in, so always use the one on your current statement.

Mail payments take five to seven business days from the time Rocky Mountain Power receives them. If you are close to your due date, mailing a payment is risky because it may not arrive in time. Use online or phone payment if your due date is within a week.

Setting up automatic payments

Automatic payments withdraw money from your bank account or charge your card on a date you choose each month. You set this up through your online account. Log in, go to "Billing and Payment," and select "Automatic Payments." Choose your payment method, the date you want the payment to come out, and whether you want to pay your full balance or a fixed amount each month.

Automatic payments eliminate the risk of forgetting to pay or missing a due date. You can change or cancel the automatic payment anytime through your account. If your bill amount varies month to month, you can set it to pay your full balance automatically, or you can set a fixed amount and pay any difference manually.

In-person payment locations

Rocky Mountain Power has payment centers in some areas where you can pay in person with cash, check, or card. Locations vary by region. To find a payment center near you, go to rockymountainpower.net, select "Pay My Bill," and look for the "Payment Locations" option. You can also call 1-888-221-7070 and ask a representative for the nearest location.

In-person payments are processed when ready, so your account is updated the same day. This is useful if you prefer to pay with cash or want to confirm your payment was received right away.

What to do if your payment does not post

If you paid online or by phone and your payment does not show on your account within the expected timeframe, log into your account and check your payment history. Online payments should appear the same business day. Phone and bank account payments take one to five business days. If more time has passed and the payment still does not show, call 1-888-221-7070 and provide your confirmation number.

If you paid by mail and your check has not posted after seven business days, call the same number. Have your check number and the date you mailed it ready. A representative can trace the payment and confirm whether it was received.
