PowerHouse Data Centers / Hillwood

A lawsuit filed May 18 at Will County Courthouse challenges the $20 billion, 795-acre Joliet Technology Center project developed by PowerHouse Data Centers and Hillwood. The 1.8-gigawatt campus in Joliet, Illinois would include 24 buildings totaling 6.9 million square feet across four sub-campuses. Plaintiffs from Joliet Residents For Responsible Growth allege the city violated due process, the Open Meetings Act, and state notice requirements during the March 19 City Council approval. The lawsuit seeks to void the council's 8-1 approval of the annexation agreement. First sub-campus completion was slated for 2028. GCs and subs should monitor litigation outcome before committing resources.
