Amazon Reveals Major Investment in Montgomery County

Amazon announces a $10 billion data center investment in Montgomery County, creating hundreds of jobs, supporting thousands of construction jobs and funding community programs.

Amazon has officially announced plans for a new $10 billion data center campus in Montgomery County. The project is expected to create 400 new jobs, support thousands of construction jobs and generate significant economic activity through construction, infrastructure investment and long-term operational growth in the region.

The investment builds on Amazon’s longstanding presence in Missouri. The company has operated in the state since 2017 and employs more than 10,000 Missourians across fulfillment and sortation centers, delivery stations and other facilities.

Due to the size of the project, Amazon's data center will be subject to Ameren Missouri's Powering Missouri Growth Plan. Containing strict consumer protection measures, the plan requires large data center customers to pay upfront 100% of all costs associated with hooking up to the energy grid. Even if they use less energy than expected, the plan requires these large customers to pay a minimum monthly demand charge of at least 80% of their maximum requested electric demand. These provisions are designed to protect consumers and are grounded in Senate Bill 4, passed by the Missouri General Assembly and signed into law by the governor in 2025.

“Amazon's investment in Montgomery County reinforces Missouri’s strong position as a hub for innovation and a state with an exceptionally skilled workforce,” said Martin J. Lyons Jr., chairman, president and CEO of Ameren Corporation. “We applaud local and state leaders who support economic growth and job creation while ensuring that consumers are protected. At Ameren, we are committed to serving all our customers with reliable service at the lowest possible cost."

Outside of the data center, Amazon is committing over $7 million in community contributions, including $3 million to support emergency dispatch services in Montgomery County, over $1 million for a new community gathering space at the County Fairgrounds and an additional $3 million in community programs. As part of those contributions, Amazon is launching a $150,000 Community Fund to provide grants for Montgomery County community projects.

This $10 billion investment further strengthens Missouri’s growing role in the digital economy and supports increasing global demand for secure, reliable and scalable cloud computing infrastructure. From a revenue perspective, Montgomery County estimates the project will generate hundreds of millions of dollars in new property tax revenue over the next 25 years.
