About the Western Union® Speedpay® convenience fee

Alliant Energy utilizes a third party, Western Union® Speedpay®, to provide you with the ability to use your credit card, debit card or electronic funds transfer to make payments.

The convenience fee is the amount Western Union® Speedpay® charges to cover processing fees and transaction costs associated with handling credit card, debit card or electronic funds transfer payments.

Other companies are able to add the price of processing these requests to their overall price of goods and services. Because Alliant Energy is a regulated utility, we are unable to do that.

By charging only the customers who use this service, it's a fair way to pay for this option. Only the customers who choose to use this service will be charged the fee.
