Ameren Missouri unveils plan to enable growth, boost reliability and create jobs in the Show-Me State

Company also highlights investments in its Smart Energy Plan

Ameren Missouri recently announced a significant change to its generation strategy, aiming to accelerate investments to support robust economic expansion, bolster reliability and create jobs throughout Missouri. The revision to Ameren Missouri's Preferred Resource Plan in its Integrated Resource Plan (IRP) is designed to ensure the 1.5 gigawatts (GW) of expected new energy demand by 2032 can be met through a balanced mix of generation resources, allowing the company to continue providing reliable and affordable energy to all its customers.

Building off the success of bringing in nearly two dozen new economic development projects in 2024, Ameren Missouri has construction agreements with several potential large load customers for new energy demand.

"These agreements are an initial step," said Mark Birk, chairman and president of Ameren Missouri. "Work remains with key stakeholders to secure these customers and provide benefits to our communities."

To support these investments in new energy generation and to provide the reliable delivery of that energy to customers, Ameren Missouri also filed its updated Smart Energy Plan with the Missouri Public Service Commission. The $16.2 billion, five-year plan calls for continued investments in modern infrastructure to enhance grid reliability and resiliency.

"Our customers depend on Ameren Missouri to continue investing in reliability, whether that's through a balanced mix of energy resources or strengthening the grid by upgrading and maintaining aging infrastructure. Through these continued investments, we are ensuring that we have a reliable and resilient energy system to serve customers today and well into the future," said Birk.

The updated generation strategy within the IRP's new Preferred Resource Plan aims to reliably serve customers and support economic development for the foreseeable future. The new plan includes:

  • Building 1,600 megawatts (MW) of natural gas generation resources by 2030, with a total planned addition of 6,100 MW by 2045.

  • Deploying a significant amount of battery storage across the Ameren Missouri service territory. The plan calls for 1,000 MW to be installed by 2030 and a total of 1,800 MW by 2045.

  • Planning for 1,500 MW of new nuclear energy generation by 2045. Nuclear operates regardless of weather and can provide a clean, steady supply of energy. Ameren Missouri continues to expect to seek an extension to operate the Callaway Energy Center beyond 2044.
