Data centers in Webster County, Missouri: 2 projects mapped
Webster County has no planning and zoning. Voters turned it down in 2005 and 2007, Presiding Commissioner Paul Ipock told the Springfield Business Journal. That is why a data center could go up on Rifle Range Road, just north of Marshfield, before most residents knew it existed. Ipock said commissioners first learned of it on April 29, 2026 from a Facebook post. The owner is Lumon Solutions LLC, formed in October 2025, whose partners include Trent Overhue, the Springfield developer who bought Plaza Towers in a 2025 foreclosure sale, and Ashton Owens. The county's May 6 statement, citing the company, described a "small-scale, high-performance computing facility" on a 5-acre site, cooled by a closed-loop system using a few hundred gallons of water a month from a residential-style well. "In short, this particular development does not appear to be one of the massive, resource-consuming hyperscale data centers that have been built elsewhere in the country," the commission said. Overhue said the center would use 10 megawatts and sits next to a Webster Electric Cooperative substation. He declined to name its customer, citing nondisclosure agreements.
About 800 people packed the Marshfield High School auditorium for a special commission meeting on May 11, the Springfield Daily Citizen reported. Residents raised water, groundwater contamination, power, noise and heat, and asked commissioners to sign a one-year moratorium that a lawyer hired by residents had drafted. When a resident asked about a small data center near Omaha that Overhue said he had been a partner in, he declined to give details, citing nondisclosure agreements, and the crowd erupted. Tom Houston, the electric co-op's general manager, said the project would not raise residents' bills; one audience member accused the co-op of soliciting it, which Houston denied. Two days later Lumon posted that it would proceed: "Political pressure does not make a lawful project unlawful. Misinformation does not create legal authority where none exists. Public outrage does not rewrite the rules in the middle of the process."

The commission warned residents that without zoning its "authority to regulate land use and development may be more limited than some of the proposals assume." On June 16 the three commissioners signed a six-month temporary moratorium on new data centers, solar, wind and battery storage systems in the county, the Webster County Citizen reported, citing concerns about grid capacity, round-the-clock noise and drainage. It does not affect the Lumon site, which was already under construction. The newspaper also reported, citing a courthouse source, that anger after the May meeting led to several anonymous threats against commissioners.
Inside Marshfield's city limits, the Board of Aldermen voted on April 23 to require a conditional use permit for data centers in the heavy industrial district, meaning public hearings and an aldermen vote. City Administrator Sam Rost said the change followed inquiries from Swarm Systems, a New York-based company. Its website had advertised a 20-megawatt "Missouri campus" on 8.2 acres at 630 George St. in the city's industrial park, "ready for service in mid-2027". In May the company said it was pausing, the Springfield Business Journal reported. "There was nothing there to stop Lumon Solutions from going ahead and rolling dozers," said Swarm's Amir Atefi. "They didn't ask anyone or tell anyone. It's not a good look for the industry, and it's not the right way to do business."
