The Joliet City Council is considering plans for a massive data center project that would be the largest in Illinois. The proposed Joliet Technology Center would sit on 800 acres of mostly farmland near the Joliet speedway. While developers say the project would bring thousands of construction jobs and 700 full-time positions, as well as $100 million in payments to the city and $2 billion in annual tax revenue, many residents packed the council meeting to voice strong opposition, citing environmental concerns about water and electricity consumption, as well as noise issues.

Why it matters

Data centers have become increasingly common across the Chicago area, but their development often faces pushback from local residents concerned about their environmental impact and strain on community resources. The Joliet proposal represents one of the largest such projects in the state, making it a high-stakes decision for the city council as they weigh the potential economic benefits against the community's quality-of-life concerns.

The details

Developers have proposed building the Joliet Technology Center on about 800 acres of mostly farmland near the Joliet speedway. The city's plan commission has already approved the project, but Monday night's packed city council meeting saw many residents speaking out against it. Opponents cited concerns over the data center's water and electricity consumption, as well as the potential for noise pollution. Several other Chicago-area communities have rejected similar data center proposals due to these types of issues. One resident presented nearly 5,000 petition signatures against the Joliet project. However, supporters argue the development would provide thousands of construction jobs and 700 full-time positions once completed, along with $100 million in direct payments to the city and an estimated $2 billion in annual tax revenue.

  • The Joliet City Council meeting took place on Monday night, March 17, 2026.
  • The city's plan commission had previously approved the data center project.

The takeaway

As data centers become more prevalent across the Chicago region, this high-stakes decision in Joliet could set an important precedent for how communities balance these competing interests.
