Microsoft’s first Fairwater data center facility in Mount Pleasant, Wisconsin, is operational. Microsoft announced completion on June 23, 2026, following equipment startup in April, and reported nearly 550 employees on site. The initial development agreement concerned approximately 315 acres between Braun Road, County Road KR, the railroad and 90th Street. Microsoft described the first facility as fulfilling its initial $3.3 billion investment pledge, with closed-loop liquid cooling designed for more than 90 percent of the facility. On September 28, 2026, the Village announced that Microsoft would redirect its annual development incentive of up to $5 million under the 2023 agreement to local economic development and property-tax relief. Microsoft’s second facility immediately to the west is a separate development scheduled for completion in 2028.
