Automated Clearing House

What is Automated Clearing House (ACH) payment?

ACH is an electronic bill payment program where you determine when to release the electronic payment from your checking account to Mississippi Power.


How is Automated Clearing House payment used?
ACH is mostly used by commercial customers who have the ability to create a Corporate Trade Exchange (CTX) or Cash Concentration and Disbursement plus Addendum transactions (CCD+).


How do I create a payment transaction?
Please contact either your financial institution or the National Automated Clearing House (NACHA), if you have any questions on how to create a CTX or CCD+ transaction.


How do I make a payment using ACH?
The transaction sent to the bank must include the payment coupon or remittance advice (10-digit Mississippi Power account number) in order to qualify for ACH payments.


Why should I consider ACH payments?
ACH payments provide increased cash flow management by minimizing payment-posting time.

Remember, we will continue to read your meter and calculate your bill each month. You will continue to receive your bill as you normally do.


How do I choose the right ACH electronic payment option?
Your company's technology system will determine what ACH payment option is available to you. If unsure of what transaction to use, contact your company's IT or purchasing department. Be advised we do not accept email or fax remittance.
