Microsoft is expanding its AI infrastructure aggressively, adding about 2 gigawatts of capacity and pursuing renewable energy to power the new facilities, including a 250-megawatt solar plant under construction in Portage County.

Microsoft is bringing the Fairwater AI Datacenter in Wisconsin online ahead of schedule, touting it as the world's most powerful AI datacenter.

Microsoft commits to stabilizing energy costs, pre-paying for energy infrastructure, and protecting nearby ecological areas as the new facilities come online.

Plans call for building additional, similarly designed datacenters across more than 70 regions in the US, expanding from its existing network of about 100 facilities and influencing energy markets, the power sector, and supply chains.

The project was first announced in September 2025 and is envisioned to deliver up to ten times the performance of today’s fastest supercomputers for AI training.

The Wisconsin-based Fairwater AI Datacenter showcases extensive fiber connectivity and a fully liquid-cooled, closed-loop system that requires no additional water after construction.

The facility will cluster hundreds of thousands of NVIDIA GB200 GPUs built on the Blackwell architecture into a seamless AI training grid to tackle frontier-scale workloads.
