Black Hills Energy bill pay works through their website, phone line, or by mail — and the method you choose depends on how quickly you need the payment posted and whether you want to set up automatic payments.
Black Hills Energy serves customers in South Dakota, Wyoming, and Colorado. If you receive a bill from them, you can pay through their official website at blackhillsenergy.com, by phone at 1-888-890-5554, or by sending a check to the address printed on your bill. Each method has a different processing time, so knowing which one to use can help you avoid late fees.
The fastest way to pay is online through their website or by phone — both post to your account within one business day. If you mail a check, allow 7 to 10 business days for it to arrive and be processed. Setting up automatic payments through their website means you never have to remember to pay, though you should still review your bill each month to catch errors.

Paying Online Through Black Hills Energy's Website
Go to blackhillsenergy.com and look for the "Pay My Bill" or "Make a Payment" button, usually near the top of the page. You will need your account number, which appears on your bill, and the amount you want to pay. The website accepts debit cards, credit cards, and bank account transfers.
When you pay by debit or credit card, Black Hills Energy charges a convenience fee — the amount varies depending on the card type and is shown before you confirm the payment. Bank account transfers (ACH payments) typically have no fee or a much smaller one. The payment posts to your account within one business day, so if your bill is due tomorrow, paying online today will usually prevent a late fee.
After you complete the payment, the website shows a confirmation number. Write it down or take a screenshot. If you ever need to dispute the payment or prove you paid on time, this number is your proof.
Paying by Phone
Call Black Hills Energy at 1-888-890-5554 to pay over the phone. Have your account number and the payment amount ready. A representative will ask which payment method you prefer — debit card, credit card, or bank account — and will process the payment while you are on the call.
Phone payments also post within one business day and carry the same convenience fees as online card payments. Like online payments, you will receive a confirmation number to keep for your records. If you are uncomfortable giving your card or bank details over the phone, the website is a safer option because the connection is encrypted.
Paying by Mail
Write a check to Black Hills Energy and mail it to the address printed on your bill. Do not send cash. Include your account number on the check so the payment is matched to your account correctly. Mail your check at least 10 business days before the due date to give it time to arrive and be processed.
The post office does not may provide delivery dates, so mailing a check the day before your bill is due risks a late fee. If you are close to the due date and need to pay, use the online or phone method instead. Keep a copy of the check or write down the check number for your records.
Setting Up Automatic Payments
Log into your account on blackhillsenergy.com and look for "Autopay," "Automatic Payments," or "Recurring Payments" in the account settings. You will choose a day each month for the payment to be deducted — many people choose the day after they receive their paycheck. You can link a bank account or provide a debit card.
Automatic payments mean you never miss a due date, and they usually have lower or no fees compared to one-time card payments. However, you should still review your bill each month before the payment goes through. If there is an error on the bill or an unusual charge, you can pause the automatic payment, contact Black Hills Energy to dispute it, and resume payments once it is resolved.
You can change or cancel automatic payments anytime through your online account. If you cancel, make sure you have another payment method in place so your next bill does not go unpaid.
What Happens If You Miss the Due Date
Black Hills Energy begins charging a late fee if your payment is not received by the due date printed on your bill. The amount of the late fee varies by state and by the size of your bill. After a certain number of days unpaid — usually 30 to 45 days — they may disconnect your service without further notice.
If you know you will miss a payment, contact Black Hills Energy before the due date. Some regions offer payment plans or hardship programs that let you spread the cost over several months instead of paying the full amount at once. Calling ahead is always better than letting the bill go unpaid, because it shows good faith and gives you options.
Choosing the Right Payment Method for Your Situation
| Payment Method | Processing Time | Fees | Best For |
|---|---|---|---|
| Online (website) | 1 business day | Convenience fee for cards; none for ACH | Paying close to the due date; avoiding fees |
| Phone | 1 business day | Convenience fee for cards | Preferring to speak with someone |
| 7–10 business days | None | Paying well in advance; avoiding convenience fees | |
| Automatic payments | 1 business day (monthly) | None or low fee | Never wanting to miss a due date |
If you have time before your bill is due and want to avoid fees, mailing a check is free. If you are close to the due date or want the certainty that your payment will post on time, pay online or by phone. If you want to remove the burden of remembering to pay each month, automatic payments are the most reliable option.
Each method has trade-offs: speed versus cost, convenience versus security, and one-time effort versus ongoing setup. The right choice depends on your timeline, your comfort with different payment types, and whether you prefer to pay the same way every month or switch based on what works that particular month.
