City of Joliet Approves Conditional Annexation for Proposed Joliet Technology Center Development

JOLIET, IL - The City of Joliet has approved the conditional annexation of approximately 795 acres for the proposed Joliet Technology Center, a major technology infrastructure project that could bring significant long-term investment, job creation, and economic activity to the community.

The annexation is tied to an agreement between the City of Joliet and PowerHouse Hillwood Holding LLC and will take effect upon the developer's acquisition of the property. The site is planned for development as a data center campus, along with supporting utility infrastructure and related improvements.

"This annexation agreement sets clear expectations for infrastructure, services, and community benefits while helping ensure the project moves forward in a responsible way," said Joliet City Manager Beth Beatty. "It also delivers substantial new revenue for local taxing bodies and long-term financial benefits for the community,"

The approval represents another important step in the City's review of a development that has the potential to expand Joliet's role in advanced technology infrastructure while helping support the community's long-term economic future. The project is expected to generate approximately $310 million in property taxes over 30 years, in addition to utility taxes. Revenue projections include $677 million for Joliet Township High School District, $76 Million for Joliet Junior College and $146 million for Will County over the same period.

As part of the broader development framework, the plan includes significant commitments to public infrastructure, utility coordination, roadway improvements, and emergency services planning. The project will create 700 permanent onsite jobs and an estimated 7,000-10,000 locally sourced construction jobs. The developer has also committed up to $100 million to improve Joliet's sidewalks, streets, and City services.

The annexation agreement also ensures that development of the property will move forward under City oversight and in accordance with approved zoning, engineering, and operational requirements.

The City of Joliet's dedicated webpage for the proposed data center project can be found at Joliet.gov. The site serves as a centralized location for available documents, materials, and updates so residents can easily access project information.
