The roar of heavy industry is getting a lot louder in Mankato. Rolls‑Royce has flipped the switch on a major expansion, putting roughly $24 million into a new logistics hub and plant upgrades that the company says will more than double output of its massive backup generators for data centers, hospitals, and airports.
The buildout includes a 250,000‑square‑foot Logistics Operations Center plus an additional $4.5 million investment at a second Mankato site, company managers said during a recent ceremony. Factory leaders say daily assembly has climbed from single‑digit units last year to roughly 14 per day now, with a target of about 28 per day within a few years.
In a company release, Rolls‑Royce said the $24 million package is expected to boost capacity and create more than 100 U.S. jobs, with the new logistics center enabling climate‑controlled assembly and faster throughput. The company projects production capacity at the Minnesota site will increase by more than 120% by 2026 and notes that sales to the data‑center market jumped nearly 50% last year.
Local reporting from the Star Tribune fills in some of the scale. The plant employs about 420 people, and the finished units are not exactly portable: each generator weighs roughly 40,000 pounds and produces more than 3,000 kilowatts. Company representatives told attendees that customers often pay “hundreds of thousands” of dollars per generator, and the facility is working through a backlog of about a year. The same account noted the company is investing $4.5 million at another Mankato production site as part of the broader expansion.
The project is getting a public assist as well. Minnesota’s Department of Employment and Economic Development has approved a $500,000 Job Creation Fund grant tied to the Mankato expansion, and city officials say they helped secure the award even though Mankato did not directly bankroll the main plant improvements. According to Minnesota DEED, the grant supports site improvements that are expected to create 25 new jobs within the first three years.
Local manufacturing cluster
Economic development officials say the expansion reinforces an already busy power‑generation cluster around Mankato. Kato Engineering, now part of Nidec, and Blue Star Power Systems both operate nearby facilities that build generators and related components, giving the region a deep bench of suppliers and experienced workers.
Profiles and filings for Nidec/Kato and Blue Star/DEUTZ on GovCon In A Box and DEUTZ outline the local footprint and recent ownership changes that have shaped the cluster.
Why factories matter for data centers
Analysts and manufacturers say the surge in AI and hyperscale cloud projects has pushed demand for mission‑critical backup power to new highs, tightening lead times and nudging prices upward. Industry coverage and company statements describe a scramble to add capacity to catch up with the boom. Reporting in Manufacturing Magazine points to growing backlogs at generator makers as data‑center construction accelerates across the United States.
What to watch next
City leaders and residents are also wrestling with what this kind of growth means for local planning. The Star Tribune reported that Mankato was set to consider a moratorium on new data‑center permits as communities weigh infrastructure strain and other impacts.
State project listings add another wrinkle. DEED’s 2025 Business Expansion Projects document frames the effort as a $35 million, 280,000‑square‑foot program with more than a hundred jobs, while company materials and local coverage lean on the $24 million logistics center figure and the company’s own job forecasts. How the city council and state programs respond will go a long way in deciding whether Mankato’s industrial growth is remembered as a durable economic win or as a case study in balancing big‑ticket expansion with local resources and long‑term planning.
