Status: Approved / Pre-Construction (March 19, 2026) | Location: Former Industrial Brownfield, South Joliet
Formally approved on March 19, 2026, following a recessed six-hour public hearing, the Joliet Technology Center represents a landmark $20 billion flagship hyperscale development in Illinois. The project is technically significant as the first in the state to comply with the 2026 POWER Act, which mandates a “Bring Your Own New Clean Capacity” (BYONCCE) approach for large-scale data centers. This requirement ensures that new energy demand is offset by dedicated clean energy generation capacity.
To meet these obligations, the developer has committed to deploying a large-scale battery energy storage system (BESS) alongside a direct transmission connection to a new 1.5GW solar and wind hybrid energy array located in central Illinois. This integrated energy strategy is designed to deliver consistent, low-carbon power for continuous hyperscale operations.
The campus is purpose-built for high-density AI and machine learning workloads, incorporating direct-to-chip liquid cooling across all server racks to efficiently manage thermal loads associated with next-generation compute. Its strategic location near the Chicago interconnection hub provides access to one of the most robust fiber networks in the United States, ensuring low-latency connectivity and high bandwidth capacity.
