Current canonical record
This record tracks Joliet Technology Center in Illinois.
The City of Joliet announced on March 19, 2026 that it approved conditional annexation of about 795 acres for the proposed Joliet Technology Center; the project website describes a $20 billion investment by Hillwood and PowerHouse. Later May reporting identified litigation challenging the zoning and approval process, so the row remains planned with litigation noted rather than marked under construction.
