Flex Pay

Take Advantage. Take Control.


Flex Pay is Ameren’s new “pay-as-you-go” payment option that puts more power in your hands — the power of greater flexibility and control over how you pay.

We know that budgeting for bills is about having the right options that work for you. We can help you keep track and you have the option to pay when it is convenient for you. Manage outstanding balances by using Flex Pay to apply 75% of each payment toward future energy usage and 25% toward the unpaid balance until it's paid off.*

With Flex Pay, say goodbye to uncertainty over your energy bill. See your daily estimated energy usage and your current account balance from the convenience of your smartphone — no more surprises.

* Unpaid amounts that have already billed will be placed in Flex Pay as a Deferred Balance. The next time your account bills there will be one more adjustment to the Deferred Balance for charges accumulated between your previous bill and the date of your enrollment in Flex Pay.
