The Joliet City Council held a regular meeting on Monday, March 16, 2026, at 4:30 PM in City Hall Council Chambers. The meeting included a public hearing on the proposed Joliet Technology Center annexation, a 795-acre data center development. Due to the state election day prohibition, the council recessed the meeting without voting on the annexation, scheduling a reconvened meeting for Thursday, March 19, 2026, at 5:30 PM. Other routine and non-controversial items were approved.
The public hearing opened at approximately 5:30 PM for the proposed annexation, rezoning to I-1 (Light Industrial), preliminary PUD, and preliminary plat of the Joliet Technology Center on approximately 795 acres near S. Rowell Road and Bernhard Road. The developer (Hillwood and Powerhouse Data Centers) presented details on the project, including: closed-loop water cooling (max 150,000 gallons per day, with spikes up to 300,000), noise mitigation plans, traffic improvements, economic impact (estimated $2.1 billion in tax revenue over 30 years, $20 million upfront community benefit), and grid reliability. Expert testimony from ComEd, Langan Engineering, Kimley-Horn, and others was provided.
Numerous public speakers (over 80 individuals) spoke during the hearing. Supporters included union representatives (Will Grundy Building Trades, IBEW, Sheet Metal Workers, LiUNA, Operating Engineers), the Joliet Region Chamber of Commerce, Lewis University, Joliet Junior College, and local residents. They emphasized job creation (7,000–10,000 construction jobs, 700 permanent high-wage jobs), tax base diversification, and the developer’s transparency and lack of incentives.
Opponents, including residents of Joliet, Elwood, Manhattan, and other nearby communities, expressed concerns about: depleting the aquifer (Joliet relies on groundwater until 2030), noise pollution (including low-frequency infrasound), increased electricity costs, lack of transparency (no Spanish-language materials, redacted FOIA documents, rushed timeline), potential health impacts (cancer, sleep deprivation), property value declines, and the speculative nature of AI demand. Several speakers urged the council to wait for the Illinois Power Act (SB 4016/HB 5513). A petition with over 4,719 signatures opposing the data center was presented.
