Ameren Missouri, a subsidiary of Ameren Corporation (AEE), has officially filed an application with the Missouri Public Service Commission to establish the Big Hollow Energy Center. This innovative hybrid facility will integrate an 800-megawatt natural gas energy center with a 400-MW battery storage unit in Jefferson County, Missouri, marking the company’s first major battery installation.

The Big Hollow project is set to bolster grid reliability and accommodate rising energy needs, with an anticipated operational date by 2028. Built on land already owned by Ameren with existing infrastructure, the project aims to reduce construction time and costs, ultimately offering a cost-efficient energy solution.

Ameren’s broader energy strategy involves deploying 1,000 MW of battery capacity by 2030 and expanding to 1,800 MW by 2042. The battery systems are designed to store excess energy and provide power for thousands of homes during peak demand phases, thereby enhancing overall grid resilience.

The project is expected to deliver significant economic benefits, including job creation and increased tax revenues for Jefferson County, particularly following the planned closure of the Rush Island Energy Center in October 2024. Ameren Missouri’s collaboration with local officials and community leaders highlights its commitment to sustainable growth and community engagement.
