Joliet Technology Center

PRJ-1099 · Site · Joliet, Illinois, United States

Record last updated Oct 28, 2026

Scope and capacity

Joliet Technology Center is Hillwood’s proposed 795-acre data-center campus in Joliet, Illinois. Project materials describe a $20 billion, 1.8 GW full-build program over roughly five to seven years, with closed-loop cooling, ComEd service and no planned onsite generation. The city conditionally approved annexation in March 2026, but building permits, utility delivery and construction remain phased. The 1.8 GW figure is a future design objective, not operating capacity.

Headline: 1,800 MW Planned / design

Numbers refer to their stated physical boundaries and are not added together. Source dates, claim dates and record updates have different meanings. Missing dates and locators are not inferred.
