AWS Plans Major Data Center Expansion in Missouri, Eyes Indiana Site

Amazon Web Services is pursuing a significant expansion of its data center footprint in Montgomery County, Missouri, while simultaneously engaging with local stakeholders in Posey County, Indiana, as the cloud giant continues to deepen its infrastructure presence across the American Midwest.

The expansion plans, which could add up to 15 new data center buildings on 890 acres of land near Danville, represent a substantial bet on a region that sits west of St. Louis and east of Columbia. A representative from Amazon informed Montgomery County commissioners of the company's intentions, though AWS has not yet acquired the property. Construction is not expected to begin before 2027 and could start as late as 2029, pending project approval.

The Danville site would operate separately from AWS's existing development in New Florence, where the company is building a 1,000-acre campus. That project is being developed in two phases: the first will see eight data center buildings constructed, while the second phase could add a further 13 buildings of similar size. In June of this year, AWS committed to investing $10 billion in the New Florence campus, underscoring the scale of its ambitions in the state. St. Louis and Kansas City remain Missouri's largest data center markets, but the Montgomery County projects signal growing interest in areas beyond those established hubs.

Meanwhile, AWS is taking a community-first approach in Posey County, Indiana, where it held an open house to discuss a potential data center project that remains in its early planning stages. The company is exploring several properties in the region, drawn in part by excess capacity on CenterPoint Energy's power grid. Keith Klein, AWS director of Data Center Solutions, emphasized the company's desire for community engagement during the open house, stating that AWS wants to understand what residents are looking for in a deployment of this size and build something together with the community. Posey County is located in southwest Indiana near Evansville, while most of the state's data centers are concentrated in Indianapolis, Gary, and South Bend.

The dual-track developments reflect a broader trend of hyperscale cloud providers pushing into secondary and tertiary markets across the United States, driven by the need for land, power, and proximity to growing demand. With a $10 billion commitment already in place for New Florence and a potential 28-building buildout across two Missouri sites, AWS is positioning the region as a key node in its national infrastructure strategy. The outcome of the Posey County evaluation will determine whether Indiana joins Missouri in benefiting from the company's expanding footprint.
