Public summary
Microsoft data center development on the former Foxconn site in Mount Pleasant, Racine County. First phase fully operational as of mid-2026. Build-out approaching ~900 MW; projected up to ~3,300 MW by late 2027 across four buildings. Oracle is separately challenging Wisconsin PSC rules requiring hyperscale developers to post hundreds of millions in financial security — an early legal test of state risk-allocation tariffs. (Data Center Knowledge, July 2026.)
Grid relevance
Large-load growth in the upper Midwest within MISO's footprint. Wisconsin's hyperscaler security-posting rules are one of the first state-level tests of who bears financial risk for large-load buildouts.
