Microsoft Granger Indiana: $1B+ AI Data Center St. Joe Farms

Status: Pre-Construction / Groundbreaking Imminent (March 2026)   |   Location: Granger (St. Joseph County), Indiana

Project Overview

Located on the historic St. Joe Farms property in Granger, Microsoft’s $1 billion+ data center campus is emerging as a strategic hyperscale deployment positioned to compete directly with Amazon Web Services’ nearby “Project Rainier” development in New Carlisle. The project underscores the intensifying infrastructure race in the Midwest, where access to land, power, and fiber connectivity is enabling a new wave of AI- and cloud-focused campus-scale investments. As of March 2026, the development has cleared its final major administrative milestone, with the St. Joseph County Board of Commissioners approving a key Memorandum of Understanding (MOU) on March 17, 2026. This approval unlocks approximately $12.5 million in pre-development activity, including critical infrastructure upgrades such as the widening of Cleveland Road and the extension of water and sewer services from the nearby Mishawaka.

A notable differentiator for this project is Microsoft’s decision to forgo traditional tax abatements, instead committing to pay full property taxes an uncommon approach for large-scale data center developments. This structure is expected to generate sustained fiscal benefits for local public services, particularly libraries and school systems, strengthening community alignment and long-term regional support. From an environmental and resource management perspective, the project has been designed to address local concerns surrounding Juday Creek and groundwater usage. Microsoft plans to implement a closed-loop cooling system, eliminating the need to draw from the local aquifer, while relying on municipal water from Mishawaka strictly for domestic and ancillary purposes.

With regulatory approvals secured and early infrastructure work underway, the project is advancing toward a construction start window in late April or early May 2026. Once operational, the campus is expected to play a key role in Microsoft’s broader cloud and AI infrastructure strategy, reinforcing its regional footprint while contributing to the Midwest’s growing position as a competitive data center hub.
