Microsoft 3,500-Acre Data Center Expansion in Cheyenne

planned

Microsoft plans a 3,500-acre expansion of its data center facilities on the south side of Cheyenne, Wyoming. This expansion is the largest annexation in Cheyenne history and represents roughly 20% of the city's existing footprint. The annexation gives the city control over land-use, water, and sewer decisions for the area tied to Microsoft's future plans. The project benefits from a Wyoming state law exemption that allows certain non-mineral processing facilities built in designated industrial or business parks to skip the state's full Industrial Siting Council review process, expediting construction timelines and reducing regulatory costs.
