Microsoft Wisconsin AI Data Center Expansion

under construction

Microsoft plans to build a second massive artificial intelligence data center in Mount Pleasant, Wisconsin, joining an existing $3.3 billion data center. The combined site will house the world's most powerful AI supercomputer, connecting hundreds of thousands of Nvidia chips. The project includes pre-paying for electrical infrastructure, a state-of-the-art cooling system using Wisconsin's climate, solar power offsetting, and new fossil fuel power generation nearby. The first data center is on track to open next year, with employment expanding from 500 to about 800 after the second center's completion.
