How to Pay Your Idaho Power Company Bill Online and by Mail

Idaho Power's main payment methods and where to use them

Idaho Power offers four ways to pay your bill: online through their website, by phone, by mail, or in person at a payment center. The online method is the fastest and gives you a record when ready. Phone and mail take longer to process. In-person payment at an Idaho Power office or authorized payment location is when ready but requires you to travel.

Each method has different processing times. Online payments typically post within one business day. Phone payments process the same way. Mail payments take 7 to 10 business days from the date Idaho Power receives them, so you need to send them early enough that they arrive before your due date. In-person payments are recorded the moment you hand over payment.

You do not need to create an account to pay by phone or mail, but you will need your account number either way. Online payment requires you to set up an account on Idaho Power's website first.

Key Takeaways

• Online payment through Idaho Power's website posts within one business day and requires you to create an account with your account number and email address.
• Phone payments reach Idaho Power the same day you call and do not require an online account, but you must have your bill or account number ready.
• Mail payments take 7 to 10 business days to process, so you must send them at least two weeks before your due date to avoid a late fee.
• In-person payment at an Idaho Power office or authorized payment location is recorded when ready and requires only your account number and payment method.

Paying online through Idaho Power's website

To pay online, go to idahopower.com and select "Pay My Bill" or "My Account". If you do not have an account, you will create one using your account number, email address, and a password. Once logged in, you can view your current bill, see your payment history, and choose your payment date.

Idaho Power accepts payments by bank account (ACH transfer) or debit card. Bank account payments have no fee. Debit card payments charge a fee that varies depending on the payment processor Idaho Power uses at the time you pay—typically between $1.50 and $3.00. Credit card payments are not accepted online. You can schedule a payment for today or for a future date up to the due date on your bill.

Once you submit payment online, you will receive a confirmation number when ready. The payment posts to your account within one business day. You can view the payment status in your online account at any time.

Paying by phone

To pay by phone, call Idaho Power's customer service line at 1-800-635-5406. Have your account number and payment method ready. You can pay with a debit card or by authorizing an ACH transfer from your bank account. Debit card payments incur the same fee as online debit payments. ACH transfers have no fee.

Phone payments are processed the same day you call, though the payment may not show in your account until the next business day. You will receive a confirmation number when the payment is complete. Keep this number for your records.

Idaho Power's phone lines are open Monday through Friday, 7 a.m. to 7 p.m. Mountain Time, and Saturday 8 a.m. to 5 p.m. Mountain Time. They are closed on Sundays and major holidays.

Paying by mail

To pay by mail, write a check or money order payable to Idaho Power Company. Do not send cash. Include your account number on the check or money order. Mail your payment to the address printed on your bill under "Make Checks Payable To" or "Mail Payment To"—this address varies by region within Idaho Power's service area.

Mail payments take 7 to 10 business days to process from the date Idaho Power receives them. To avoid a late fee, your payment must be received by your due date. This means you should mail your payment at least two weeks before the due date. If you are close to the due date, use online or phone payment instead.

Keep a copy of your check or the money order receipt for your records. You can track whether your payment has been received by logging into your online account or calling customer service.

Paying in person at an Idaho Power office

Idaho Power has payment centers in Boise, Pocatello, and other locations throughout their service area. You can find the nearest office and its hours on idahopower.com under "Pay in Person" or by calling 1-800-635-5406. Bring your account number and a payment method—cash, check, debit card, or money order.

In-person payments are recorded when ready and do not incur a fee. You will receive a receipt on the spot. This method is useful if you need to pay urgently or prefer to hand over payment directly.

Setting up automatic payments

Idaho Power allows you to set up automatic monthly payments through your online account or by phone. You can choose to pay the full bill amount each month or a fixed amount you specify. Automatic payments are deducted on a date you choose, typically around your bill due date.

Automatic payments use ACH transfer from your bank account and have no fee. You can change or cancel automatic payments at any time through your online account or by calling customer service. Even if you have automatic payments set up, you should still review your bill each month to make sure the amount is correct.

What to do if you cannot pay your full bill

If you are unable to pay your full bill by the due date, contact Idaho Power before the due date to discuss your options. Idaho Power offers payment plans that allow you to spread your balance over several months. You can set up a payment plan by calling 1-800-635-5406 or through your online account.

If you do not pay by the due date and do not have a payment plan in place, Idaho Power will charge a late fee and may eventually disconnect your service. A payment plan prevents disconnection and gives you time to catch up without additional penalties.
