Three ways to pay your Idaho Power bill

Idaho Power offers three main payment methods: online through their website, by phone, or by mail. The online option is fastest and gives you a record instantly. Paying by phone takes a few minutes and works if you do not have internet access. Mailing a check works but takes longer — typically 7 to 10 business days to reach their processing center.

Each method requires your account number, which appears on your bill. If you pay online or by phone, you can choose to pay immediately or schedule a payment for a future date. This matters if you want to time the payment with your paycheck or avoid overdraft fees.

Key Takeaways

  • Idaho Power's online bill pay portal at idahopower.com is the fastest way to pay and shows confirmation instantly.
  • You can pay by phone at 1-800-635-4328 during business hours, and the payment posts within one business day.
  • Mailing a check to Idaho Power's lockbox address takes 7 to 10 business days, so plan ahead if your due date is soon.
  • Setting up automatic payments through your bank or Idaho Power's AutoPay program prevents missed due dates.
  • Your account number appears on your bill and is required for all payment methods.

Paying online through Idaho Power's website

Go to idahopower.com and look for the "Pay My Bill" link on the homepage. Click it and enter your account number and ZIP code. You will be asked to create a login if you do not already have one — this takes about two minutes and requires an email address.

Once logged in, you can see your current balance and due date. Enter the amount you want to pay (you can pay the full balance or a partial amount) and choose your payment date. If you pay today, the transaction posts within one business day. If you schedule it for a future date, Idaho Power processes it on that date. You will receive an email confirmation with a confirmation number — save this in case you need to reference the payment later.

Idaho Power does not charge a fee for online payments made directly through their website. Some third-party payment processors charge a fee, so stick with idahopower.com to avoid extra costs.

Paying by phone

Call Idaho Power's automated payment line at 1-800-635-4328. You will need your account number and a debit card or bank account information. The system walks you through selecting your payment amount and date. The entire call usually takes 3 to 5 minutes.

If you prefer to speak with a representative, you can also call during business hours (typically Monday through Friday, 7 a.m. to 6 p.m. Mountain Time) and ask to pay over the phone. A representative will take your payment information and process it the same way. Phone payments post within one business day.

Paying by mail

Write a check or money order payable to Idaho Power Company. Include your account number on the check. Mail it to the address shown on your bill — Idaho Power uses a lockbox service, so the address may differ from their main office.

Mail payments take 7 to 10 business days to arrive and be processed. If your due date is within two weeks, mailing is risky because the payment may not arrive in time. If you must mail a payment and the due date is close, call 1-800-635-4328 to let Idaho Power know a check is coming — this can prevent a late fee while the payment is in transit.

Setting up automatic payments to avoid missed due dates

Idaho Power's AutoPay program withdraws your bill amount automatically on your due date each month. You can set it up through your online account or by calling 1-800-635-4328. You will need to provide your bank account number and routing number, or a debit card number.

AutoPay is free and removes the risk of forgetting to pay. You can change or cancel it anytime through your account. If your bill amount varies month to month (which is common with heating or cooling seasons), you can set AutoPay to pay the full balance due rather than a fixed amount.

Some people worry about losing control of their payment date. With Idaho Power's AutoPay, you choose the date — it does not have to be the due date. You can set it for the day after you get paid, for example, to make sure the money is in your account.

What to do if you cannot pay by the due date

If you know you will miss the due date, contact Idaho Power before the date arrives. Call 1-800-635-4328 and explain your situation. Idaho Power may be able to extend your due date by a few days or set up a payment plan if you owe a large amount.

Late fees apply if payment is not received by the due date shown on your bill. The fee is typically a percentage of your balance. If you pay late, the fee is added to your next bill. Contacting Idaho Power ahead of time does not may provide an extension, but it gives you a chance to work something out rather than facing a surprise fee.

Keeping track of your payment history

Log into your Idaho Power account online to see a record of all payments you have made. The payment history shows the date you paid, the amount, and the confirmation number. This is useful if you need to dispute a charge or prove you paid on time.

If you pay by mail, keep a copy of the check or the envelope you mailed it in. If you pay by phone, write down the confirmation number given to you. These records protect you if there is ever a question about whether a payment was received.

Frequently Asked Questions

Can I pay my Idaho Power bill through my bank's bill pay service?

Yes. Many banks offer bill pay services that let you schedule payments to Idaho Power directly from your checking account. Check with your bank to see if they support Idaho Power. The payment will take 5 to 7 business days to arrive, so plan ahead. Using your bank's bill pay is free and does not involve giving your account information to Idaho Power directly.

What happens if I pay more than I owe?

The overpayment stays on your account as a credit. It will be applied to your next bill. If you want a refund instead, contact Idaho Power and request one — they will mail you a check, though it may take several weeks.

Is there a fee for paying my bill online?

No, there is no fee when you pay directly through idahopower.com. Some third-party payment websites charge a convenience fee, so avoid those and use Idaho Power's official website instead.

How do I know if my payment went through?

If you pay online, you receive an email confirmation immediately with a confirmation number. If you pay by phone, the system gives you a confirmation number before you hang up. Log into your account the next business day to see the payment reflected in your balance.

Can I change my AutoPay date if I get paid on a different schedule?

Yes. Log into your account and edit your AutoPay settings anytime. You can choose any date between the 1st and the 28th of the month. If you change jobs or your pay schedule shifts, you can update it without canceling and restarting the service.
