Microsoft Fairwater 1
A hyperscale AI campus by Microsoft in Mount Pleasant, WI, on the MISO grid. Status: operating, expanding.
Grid and gas impact
At full buildout this campus is announced at 1,480 MW. After phasing to 2030 and weighting by build stage, the index expects about 799 MW running by 2030.
At that level it would use about 5,249 GWh of electricity a year, roughly what 486,000 US homes use (EIA average of about 10,800 kWh per home), and add about 62.5 MMcf/d of natural gas burn on an average day, counting both on-site generation and the region's gas-fired power plants.
Its rating is driven by grid load: power is expected to come mostly from the utility grid, so the effect shows up in transmission, capacity and generation needs, and in the gas burned by the region's power plants. Rated 3 of 4 bolts. Solid bolts mean the campus is operating or under construction.
Research note. dcmap also lists a 338 MW Azure figure for the site; 1,480 MW is the program total.
