Mount Pleasant datacenter project update
Project overview
Microsoft is developing a datacenter campus in Mount Pleasant, Wisconsin.
Why datacenters are needed
Datacenters provide the physical infrastructure for the technology we depend on at work and in our personal lives. Whenever you open an app on your phone, join a virtual classroom or meeting, snap and save photos, or play a game with your friends online, you are using a datacenter. Local businesses, government, hospitals, and schools rely on datacenters every day to deliver goods and services to you.

June 22, 2023 – Community info session recap
Microsoft hosted a community information session about the planned datacenter campus in Mount Pleasant on June 22, 2023.
Microsoft appreciated the opportunity to talk with around 150 community members who participated in the meeting and visited stations to talk with subject matter experts. The meeting stations focused on an overview of datacenters, initial conceptual plans for the Mount Pleasant datacenter campus, construction, sustainability, and Microsoft’s partnerships in the community.
The meeting included remarks from Shirin O’Connor, Corporate Vice President for Microsoft; Trustee Nancy Washburn from Village of Mount Pleasant; and County Executive Jonathan Delagrave from Racine County.
In talking with community members, Microsoft staff heard comments and responded to questions about jobs, supplier hiring, water use, Lamparek Creek, construction timeline, and community partnerships. The Microsoft team was also joined by our community partners Root Pike WIN and gener8tor who also engaged with attendees to share about their efforts.
