Chicago has approved a construction permit for HydraVault to build a 20 megawatt AI ready data center in the South Loop. The project marks another step in the city’s expanding digital infrastructure and signals its growing role in advanced computing. It will be one of the few downtown facilities designed specifically for artificial intelligence, machine learning, and low latency trading operations.
Located near Chicago’s main fiber routes, the site offers strong connectivity and proximity to major customers. HydraVault plans to support rack densities of up to 200 kilowatts. Construction is expected to begin in fall 2025, with early user access planned for late 2026.
The building is designed by Gensler and will be constructed by Power Construction. It will feature a closed loop, waterless cooling system and aim for a Power Usage Effectiveness of 1.19, a leading efficiency target. Although Chicago already hosts several downtown data centers, HydraVault’s project stands out for its scale and density. Its central location also raises new questions about power supply, sustainability, and local impact.
HydraVault’s move into Chicago reflects a broader national push to expand and localize AI ready computing capacity. As the city attracts more large scale digital investments, officials and residents will watch how projects like this balance growth, energy use, and environmental goals.
At the same time, Chicago continues to advance other major infrastructure efforts. The city is modernizing O’Hare International Airport under the O’Hare 21 Terminal Area Plan. It has also begun a $138 million rehabilitation of the century old Lake Street Bascule Bridge. Together, these projects show how Chicago is strengthening both its physical and digital foundations for the next generation of growth.
