13 data centers and projects on our map in Missouri, including 5 projects we track in detail. Each one links to its source. Below: where they are by county, the projects in the news, and the latest reporting from both sides.
See Missouri on the map. Existing facilities come from OpenStreetMap, a community-maintained public map that is incomplete; proposed, under construction and blocked projects are tracked one by one from news, filings and official records.
Blocked, paused or withdrawn City council voted 7 to 1 in May 2026 to make its data center ban permanent
St. Charles, St. Charles County
St. Charles made permanent a one year moratorium adopted after widespread opposition to a proposed data center of about 1 billion dollars off Highway 370. St. Charles County separately approved a six month countywide pause in July 2026.
Issues raised: zoning, water, power, opposition
Blocked, paused or withdrawn Board of Aldermen removed data centers from the zoning ordinance, blocking the project
Peculiar, Cass County · Operator: Diode Ventures
$1.5 billion · announced 2024-01
A proposed 504 acre data storage and technology park south of Kansas City. After hundreds of residents from Peculiar and Raymore objected, the Board of Aldermen reversed course and stripped the data center definition from the light industrial zoning code.
Issues raised: zoning, opposition, power, water
Proposed developer sued city September 17 over renewables and community benefits conditions
St. Louis, St. Louis City · Operator: TerraWatt
120 MW · $3.1 billion
TerraWatt is planning a $3.1 billion, 120 megawatt data center on 11 acres in Midtown St. Louis. The developer sued the city on September 17 over a use permit requirement to install 2.4 megawatts of on-site renewables and to secure Board of Aldermen approval of a community benefits agreement.
Issues raised: opposition, power, zoning, air-pollution
Proposed Announced May 2026, described as one of the largest tech investments in state history
Montgomery City, Montgomery County · Operator: Google
$15 billion · announced 2026-05
Google announced a data center campus in rural Montgomery County, Missouri, reported at about 15 billion dollars. Debate centers on electricity demand, water use and the size of state and local incentives.
Issues raised: power, water, tax-incentives, jobs
Under construction First building complete, further buildings still being built
Kansas City, Clay County · Operator: Meta
$1 billion · announced 2022-03
A Meta campus in the Northland section of Kansas City where the first building opened in 2025 and additional buildings remain under construction. The project preceded a 2026 city zoning change that made new data centers harder to approve.
Issues raised: zoning, power, water, jobs, tax-incentives
The city detailed enforcement terms for the TerraWatt Armory project, which promises $445 million in tax revenue over ten years: $15,000 in liquidated damages for every $100,000 revenue shortfall and $2,000 per job below staffing targets that scale from 25 to 100 employees. City officials said the developer is barred from seeking local tax abatements.
Check it: The revenue and jobs numbers are consultant projections, not audited figures; the developer has also filed suit challenging some city requirements.
Axios reported that Missouri currently has about 340 megawatts of operating data center capacity across 11 facilities, and that 50 planned projects would push that total past 7,400 megawatts if all are built. The story cites Google's Project Mica in the Northland at up to 500 megawatts and the Nebius Independence campus at about 800 megawatts, running on its own on-site natural gas plant.
Check it: The 7,400 MW figure counts announced and proposed projects, not built capacity, and many announced projects are downsized, delayed, or canceled.
TerraWatt partner David Lambiaso sued the St. Louis Board of Adjustment over two conditions attached to a use permit for a proposed $3.1 billion, 120 megawatt data center at the former Famous-Barr warehouse. The suit says a requirement to use 2.4 megawatts of on-site renewables and to secure Board of Aldermen approval of a community benefits agreement exceed the board's authority, and city officials point to a projected $445 million in tax revenue over ten years.
Check it: Read the complaint to see whether it challenges the conditions on state law grounds or only on city charter authority.
About 200 people gathered at the Missouri Capitol rotunda during the legislature's veto session to call for a statewide moratorium on hyperscale data center construction, an end to tax incentives, and stronger community input rules. Governor Mike Kehoe has publicly backed data center investment; a scheduled House committee hearing on data center regulation had been canceled.
Check it: No moratorium bill is currently before the legislature; the rally targets the 2027 session that convenes in January.
