Ameren Missouri

The utility company was found in violation of the Clean Air Act for failing to install pollution controls when it updated the Rush Island Energy Center.

The Environmental Protection Agency estimates Rush Island released 275,000 tons of sulfur dioxide after it was updated without required pollution controls in 2007 and 2010.

Ameren Missouri has announced plans to expand its Community Solar program with a third solar facility to meet growing demand for renewable energy.

The plant would be located on the site of a former coal plant in south St. Louis County. Proponents of renewable energy say more transparency is needed as the utility plans an $800 million investment in a fossil fuel energy source.

The company was given a choice by a federal court to either shut down the Rush Island Energy Center or add expensive pollution controls.

Ameren Missouri has plans for solar starting next year, wind in 2026 and battery storage in 2027, with various projects to add capacity in those categories lasting through the mid-2030s.

The additions contribute to Ameren’s goal to reach net-zero carbon emissions by 2045.

Ameren Missouri customers would have to pay an average of $12 more a month for electricity if state regulators approve a proposed rate hike.
