Ameren Rate Increase Approved by Public Service Commission

Ameren Missouri customers will now be digging deeper to pay for electric use after the Missouri Public Service Commission signs off on two agreements setting new rates to be charged.

The commission approved the two unopposed agreements between the various parties in the case which allows Ameren to increase rates by $355 million which was $91 million less than Ameren’s original request.

The approval will not affect the residential customer’s monthly charge of $9 which is a fixed charge to cover a portion of providing service to a location irrespective of energy consumption.

Ameren also agreed not to seek ratepayer recovery of amounts for mitigation ordered  in federal litigation regarding the company’s Rush Iland Energy Center’s air pollution and will continue its Fuel Adjustment Clause to adjust rates up or down based on the cost of fuel.

FOR IMMEDIATE RELEASE
PSC Approves Agreement in
Ameren Missouri Electric Rate Case
APRIL 23, 2025
JEFFERSON CITY, Mo. — On Wednesday, April 23, 2025, The Missouri Public Service Commission approved

two agreements setting new rates for electric customers of Union Electric Company d/b/a Ameren Missouri.
The Commission approved two unopposed agreements between the parties in the case. Ameren Missouri,
Commission Staff, Missouri Industrial Energy Consumers, Consumers Council of Missouri, Renew Missouri
Advocates, AARP, Metropolitan Congregations United, and Midwest Energy Consumers Group were
signatories to both agreements. The Office of the Public Counsel was not a signatory to one agreement and
Sierra Club was not a signatory to either agreement, but neither party opposed either agreement.
Under the agreements, Ameren Missouri will increase rates by $355 million. The amount approved by the
Commission was $91 million less than Ameren Missouri’s original request.
The residential customer monthly customer charge of $9 will not be increased. The customer charge is a fixed
monthly amount that covers a portion of the cost of providing service to a location irrespective of energy
consumption. Additionally, the parties agreed to amounts and terms for several low-income programs including
the Keeping Current and Keeping Cool program, the New Start program, the Critical Needs program, and the
Low-Income Weatherization program.
Under the agreement approved by the Commission, Ameren Missouri agreed to not seek ratepayer recovery of
amounts for mitigation ordered in federal litigation regarding Ameren Missouri’s Rush Island Energy Center’s
air pollution. Ameren Missouri will continue its Fuel Adjustment Clause, which allows Ameren Missouri to
adjust its rates up or down based upon the cost of fuel.
The Missouri Public Service Commission regulates investor-owned electric, natural gas, steam, manufactured
housing and modular units, water and sewer companies, and has limited authority over telephone providers in the
state. The Commission ensures the public has access to safe, reliable and reasonably priced utility service. The
Commission must balance the interests of the public – ratepayers – as well as company shareholders. In proceedings
before the Commission, rates are set to allow the utility company an opportunity – but not a guarantee – to earn a
reasonable return on its investment after recovering its prudently incurred expenses.
Ameren Missouri serves approximately 1.2 million electric customers in Missouri.
