The fastest way to pay Mississippi Power
Mississippi Power offers four main ways to pay your bill: online through their website, by phone, by mail, or in person at a payment location. The online method is fastest — you can pay immediately without waiting for a check to arrive or speaking to anyone. Go to mississippipower.com, log into your account, and select "Pay My Bill" to complete payment in minutes using a bank account or debit card.
If you prefer the phone, call 1-800-488-8035 during business hours. A representative will take your account number and payment information. By mail, send a check or money order to the address printed on your bill — allow 10 to 14 days for it to reach Mississippi Power and post to your account. In-person payment locations exist throughout Mississippi; you can find the nearest one on the company website or by calling the number above.
Online and phone payments typically post within one business day. Mail payments take longer, so if your bill is due soon, use online or phone payment to avoid a late fee. Late fees apply if payment is not received by the due date shown on your bill.
Key Takeaways
- Online payment through mississippipower.com is the fastest method and posts within one business day.
- You can also pay by phone at 1-800-488-8035, by mail to the address on your bill, or in person at a payment location.
- Late fees apply if your payment does not arrive by the due date, so use online or phone payment if your bill is due within a week.
- Your account number appears on your bill and is required for all payment methods except online, where you can log in instead.
- Mississippi Power does not offer automatic payment setup through their website, but you can arrange recurring payments by phone.
Setting up automatic or recurring payments
Mississippi Power does not provide an automatic payment option through their website, but you can arrange recurring payments by calling 1-800-488-8035. A representative will set up a schedule to deduct payment from your bank account on a date you choose — usually around your bill due date. This prevents missed payments and late fees without requiring you to log in each month.
When you call, have your bank account number and routing number ready. Mississippi Power will confirm the amount and frequency before the first payment is processed. You can change or cancel the arrangement at any time by calling the same number.
If you prefer not to give your bank details over the phone, stick with online payment each month. It takes only a few minutes and gives you full control over when the payment goes through.
Understanding your bill and account login
Your Mississippi Power bill shows your account number at the top, your current charges, your due date, and the amount owed. The bill also breaks down what you used — kilowatt-hours of electricity — and the rate you paid per unit. If you use more electricity in summer (for air conditioning) or winter (for heating), your bill will be higher in those months.
To view your bill online anytime, create an account at mississippipower.com using your account number and the service address on your bill. Once logged in, you can see your current and past bills, your usage history, and payment history. This is useful if you want to track whether your bill is rising and why, or if you need to confirm a payment went through.
If you forget your login password, use the "Forgot Password" link on the website to reset it. You will need access to the email address you registered with.
What to do if you cannot pay on time
If you know you cannot pay by the due date, contact Mississippi Power before the deadline. Call 1-800-488-8035 and explain your situation. The company may offer a short extension or a payment plan that lets you split the bill into smaller amounts over several weeks. An extension or plan does not erase the late fee if one has already been applied, but it can prevent one from being added if you arrange it before the due date passes.
Mississippi Power also has a Low Income Home Energy Assistance Program (LIHEAP) that may help pay your bill if your household income falls below a certain level. This program is run by the state, not by Mississippi Power directly. You can learn more by contacting your local community action agency or calling the Mississippi Department of Human Services.
If your service has been disconnected due to non-payment, you will need to pay the full past-due amount plus a reconnection fee to restore power. Reconnection usually happens within one business day of payment.
Checking your usage and lowering your bill
Your bill shows how many kilowatt-hours you used that month. If the number seems high, log into your online account to see your usage for the past 12 months. A sudden spike often points to a specific cause — a broken air conditioner running constantly, a water heater failure, or an appliance left on by mistake.
To lower your bill over time, look for ways to use less electricity: set your thermostat a few degrees higher in summer and lower in winter, use LED light bulbs, unplug devices when not in use, and run large appliances like washers and dryers during off-peak hours if possible. Mississippi Power's website has energy-saving tips specific to your region.
If you see an unusually high bill and cannot explain it, contact Mississippi Power to ask whether a meter reading error occurred or whether your bill includes an estimate rather than an actual reading. Meter errors are rare but do happen, and the company will investigate if you request it.
Payment methods and fees
Mississippi Power accepts payment by bank account, debit card, and credit card online and by phone. Paying by check or money order by mail is also free. Some payment methods may carry a small fee — for example, paying by credit card online may add a processing charge — so check the website before you choose your method.
In-person payments at authorized locations are free. If you pay at a retail location that is not operated by Mississippi Power (such as a check-cashing service), that location may charge you a fee; ask before you pay.
Late fees apply if your payment is not received by the due date. The amount varies but is shown on your bill. If you are on a payment plan, make sure you understand the due date for each installment, because a missed installment payment can also trigger a late fee.
Frequently Asked Questions
How long does it take for an online payment to show up on my account?
Online payments typically post within one business day. If you pay on a weekend or holiday, it may take until the next business day. You can check your payment status by logging into your account on mississippipower.com.
Can I pay someone else's Mississippi Power bill?
Yes, you can pay another person's bill online or by phone if you have their account number. Online, enter their account number instead of logging in. By phone, provide the account number to the representative. The payment will post to that account.
What happens if I pay more than I owe?
The overpayment becomes a credit on your account and will reduce your next bill. If you want a refund instead, contact Mississippi Power and request one. Refunds typically take two to four weeks to arrive.
Is there a penalty for paying my bill early?
No. You can pay your bill anytime before or on the due date without penalty. Paying early does not lower your bill or earn you a discount, but it ensures you will not be late.
What if my bill is estimated instead of based on an actual meter reading?
Mississippi Power estimates bills when they cannot access your meter. The estimate is based on your past usage. When they read your meter, the next bill will adjust for any difference. If you think the estimate is wrong, you can request an actual meter reading by calling 1-800-488-8035.
