In brief

What makes it notable.

  1. Four single-story data centers of about 2.5 million square feet on a 672-acre campus, planned for 902 MW of critical IT with closed-loop liquid cooling and minimal water use.
  2. We Energies serves the site under a dedicated rate with Vantage underwriting all power infrastructure, as nearly 2 GW of new generation is added. A 1.3 GW grid connection is targeted by end of 2027.
  3. Cloverleaf Infrastructure assembled the roughly 1,900-acre site and its power path. Groundbreaking was December 2025, with a team of four general contractors and full buildout targeted for 2028.
