Microsoft has paused construction on a significant portion of its $3.3 billion data center campus in Mount Pleasant, Wisconsin, raising questions about the future of the expansion. This decision comes as the company reviews recent technological changes that could impact the design and scope of the project. Although the company is moving ahead with the first phase of development, work on later stages has been temporarily halted.
Why Did Microsoft Pause Construction on the Mount Pleasant Data Center?
Microsoft announced that it has paused the construction of the second phase of its Mount Pleasant data center campus to evaluate recent technological changes. The company is assessing how these changes might affect the scope and design of the remaining phases of the project. The evaluation is expected to take several months, with Microsoft planning to meet with state officials after completing the review.
In a statement to Wisconsin Public Radio (WPR), Microsoft explained: “We have paused early construction work for this second phase while we evaluate scope and recent changes in technology and consider how this might impact the design of our facilities.”
While this delay has generated interest, Microsoft confirmed that its commitment to the Wisconsin data center project remains strong. The company emphasized that the first phase of construction, which is already underway, will continue without interruption.
What Impact Will This Have on the Data Center Project?
The Mount Pleasant data center campus spans multiple sites, and while construction is still progressing on one of the key parcels, work has paused on other sections. Construction is continuing on a 215-acre plot located on 90th Street, which is expected to be completed by the end of 2025. However, work on a 115-acre parcel to the west and a 791-acre plot along Durand Avenue has come to a halt.
Microsoft had initially broken ground on the 90th Street parcel in 2023, marking the start of the development. The company had also secured approval for an additional 1,000-acre expansion earlier in the year. As part of this expansion, Microsoft has been purchasing parcels of land, including a significant 160-acre plot acquired for $43 million in August 2024.
Despite the halt in construction on some areas, Microsoft remains confident in its long-term commitment to the project. Local officials have indicated they do not expect any changes to the overall scope or nature of the data center campus. Sean Ryan, spokesperson for the village of Mount Pleasant, said, “We appreciate Microsoft being transparent with village leaders about the construction timeline for its Mount Pleasant data centers.”
Microsoft’s $3.3 Billion Commitment to Wisconsin
The data center in Mount Pleasant is a critical part of Microsoft’s strategy to expand its cloud infrastructure. The company has committed to investing $3.3 billion in the state by 2026. This investment is part of Microsoft’s broader plan to build and expand its data center footprint to support its growing cloud and edge computing needs. The Mount Pleasant data center will serve as a vital hub for Microsoft’s cloud operations, and the company is on track to meet its investment commitment despite the temporary delay.
According to Microsoft’s statement, the company remains focused on the first phase of the Mount Pleasant project. “Our commitment to and construction of our planned data center campus continues with high priority for our business,” the company said, stressing that the pause in construction will not derail the overall project.
Will New Cooling Technology Be Integrated?
Microsoft’s data center in Mount Pleasant is expected to incorporate cutting-edge technologies, including a closed-loop, zero-water evaporation cooling system. This technology is designed to reduce the environmental impact of cooling systems, a significant consideration for companies with large-scale data center operations. The same cooling system will also be used at Microsoft’s Phoenix, Arizona, data center.
The pause in construction may be related to efforts to integrate this new cooling technology into the design. Although Microsoft has not confirmed this directly, the company’s push for more sustainable cooling solutions in its data centers is a key part of its strategy to reduce the environmental impact of its operations.
What’s Next for Microsoft’s Mount Pleasant Data Center?
While the second phase of the Mount Pleasant data center is on hold, Microsoft is pressing ahead with the first phase of construction. The company expects to complete work on the 90th Street parcel by the end of 2025. Once the technological evaluation is complete, construction will resume on the remaining parts of the campus.
In addition to the pause, Microsoft continues to purchase land for the expansion of the Mount Pleasant campus. The 160-acre parcel acquired in August is just one of several strategic purchases the company has made to secure the necessary land for its long-term growth.
Microsoft’s Long-Term Strategy and Cloud Infrastructure Expansion
The Mount Pleasant data center campus is part of Microsoft’s broader strategy to expand its cloud infrastructure to meet growing global demand for cloud services. With the increasing adoption of cloud computing and edge solutions, the need for data centers capable of handling vast amounts of data and providing high availability has never been greater.
Microsoft’s investment in the Mount Pleasant area will help solidify its position as a leader in the cloud computing space. The data center will provide key services for Microsoft’s Azure cloud platform and support the growing demand for data storage, computing power, and networking solutions.
