DataNews Editorial Team
TeraWatt Infrastructure is co-developing a planned 120 MW, 525,000-square-foot hyperscale data center in Midtown St. Louis. The project has received a conditional use permit and a community benefits agreement, but remains pre-construction amid community opposition and litigation.
- The Midtown St. Louis facility is planned at 120 MW and 525,000 square feet; it is not under construction.
- TeraWatt Infrastructure is named as a co-developer and the data center is intended to anchor the Armory Innovation District.
- The project has secured a conditional use permit and community benefits agreement.
- Construction is planned to begin in August 2027 and conclude by late 2029.
- Community opposition and litigation represent unresolved execution risks.
A 120 MW hyperscale data center is planned for the former Macy’s and Famous-Barr warehouse site near the historic Armory building in Midtown St. Louis, Missouri. TeraWatt Infrastructure is identified as a co-developer of the 525,000-square-foot facility, which is intended to serve as the anchor asset of the privately funded Armory Innovation District.
The wider district carries a stated total-project value of $3.1 billion. That figure applies to the Armory Innovation District as a whole and should not be treated as data-center CAPEX. The development has secured a conditional use permit and a community benefits agreement, although construction has not yet begun.
The current schedule calls for construction to start in August 2027 and conclude by late 2029. These dates remain planned milestones rather than confirmed delivery dates. The project has drawn community opposition and is linked to legal disputes, the details and potential schedule effects of which have not been disclosed in the available material.
For the St. Louis market, the proposal represents a sizeable planned addition to a region that already hosts more than a dozen operational data centers, with three more under construction and up to 10 in various stages of planning. If executed at the stated scale, it could strengthen St. Louis’s position as a regional market for large data-center development. At the same time, the case highlights how community and legal challenges can remain material execution risks even after local land-use approvals have been secured.
The developer projects that the broader district will create more than 1,000 temporary union construction jobs and 200 permanent on-site positions. Those employment figures are developer projections, not confirmed outcomes.
If delivered as proposed, the facility would add a large-scale hyperscale development to the St. Louis market. The project also illustrates that municipal approvals do not eliminate delivery risk where local opposition and legal disputes remain unresolved.
