CUB Power Deal Calculator

Welcome to CUB's Ameren Power Calculator

Many residential customers in Illinois now choose an alternative electric supplier for power (either individually or as part of a municipal aggregation deal with their community) instead of Ameren. But is yours the best deal?

CUB’s Ameren Power Calculator lets you compare alternative supply rates with the regulated utility’s rates in order to determine which plan will save most.

(ComEd consumers may use CUB's ComEd Power Calculator to compare rates.)
