Opposition and litigation at this site

Yes. Armory Innovation District Data Center in St. Louis, Missouri is or has been the subject of litigation over its siting, permitting, or operation. Pending, filed August 28, 2026, St.

A new status, a permit, a reception finding, or a lawsuit. Nothing else, ever.

How the community has taken it

Reception is a sourced signal, not an editorial judgment: in litigation means the facility is or has been the subject of a lawsuit related to its siting, permitting, or operation.

Pending, filed August 28, 2026, St. Louis. Proposed $3 billion hyperscale data center near the Armory, Midtown St. Louis, redeveloped by David Lambiaso. Approved with conditions including a $15.75M community benefits fund, no local tax abatement sought, closed-loop cooling, rooftop solar/green-roof requirements, and a target of 50% renewable energy within five years; subject to potential appeal.

Power and water

Conditional use permit requires renewables to supply 50% of the center's power in its first five years and 100% within 10 years, plus 2.4 MW of renewable energy on the site. Developer TerraWatt's Sept. 2026 certiorari petition calls the renewable conditions 'practically impossible on the 11-acre site'. Utility not named.

Notes on the record

St. Louis Board of Public Service approved the conditional use permit 5-0 on 2026-04-22; the Board of Adjustment upheld/amended it on 2026-07-30. No tenant has been named as of August 2026; targeted for full operation by end of 2028. Officially branded the 'Armory Innovation District.'
