Rate hike funds wind and solar as Ameren raises rates 12%

Missouri — Missouri residents will experience an approximate 12% increase in their Ameren electric bills starting June 1, 2025.

This change comes after the Missouri Public Service Commission approved two agreements on Wednesday, setting new rates for Ameren Missouri’s electric customers.

Under the agreements, Ameren Missouri will raise rates by $355 million, which is $91 million less than the company’s original request.

Despite the increase, the current residential customer charge of $9 will remain unchanged.

Steve Wills, Senior Director of Regulatory Affairs with Ameren, explained the reasons behind the rate hike.

“We are having to invest in our generation system,” said Wills. “The wind and solar is the lowest cost energy producing resources we have right now. A lot of that, you know, stems from tax credits that are available that Ameren Missouri’s taking advantage of, and also just the fact that this is no fuel cost at all associated with those resources. So we do look to have a balanced mix so that we still have dispatchable resources that don’t depend on the weather.”

Financial assistance programs remain available for those in need.
