Mesa Power Solutions opened a $70 million manufacturing campus in Evansville, Wyoming on August 12, 2026. The site at One Mesa Way covers 220,000 square feet. About 180,000 square feet of that is manufacturing floor. The rest, roughly 40,000 square feet, is office space. Mesa moved 300 employees onto the campus. The company builds natural gas and liquid propane generator sets. Those units serve prime power, standby power and microgrid duty. Mesa also runs a plant in San Antonio. Counting both sites, it puts annual output at up to 2 GW of power generation equipment. Chief Executive Scott Gromer tied the spending to Wyoming’s push on energy production and domestic manufacturing. Mesa expects the campus to return $200 million to the state economy by 2030. The project ran about three years from concept to opening. The town calls it one of its largest business developments.
Mesa points the equipment at data centers, utilities, healthcare providers and industrial plants. The generator sets carry telemetry that reports operating data while the units run. Prime power machines serve as a site’s main supply. Standby machines sit idle until an outage. Mesa sells PowerCore and PowerYard modular microgrid packages into the same customer base. Those packages pair the engines with distribution equipment inside a factory-built enclosure.
Why It Matters
The 2 GW number describes what two factories are able to build in a year. It is not a backlog. It is not a set of signed orders either, and Mesa has published neither figure. Read it as a ceiling on supply, not as a measure of demand.
Demand still drives the story. On-site gas generation is what a data center developer reaches for when the interconnection queue outlasts the build schedule. A gas engine arrives on a truck. A utility service upgrade arrives after a study cycle that now runs years in most markets. That gap is the business case for a plant like this one. The trade goes the other way on fuel and permits. Prime power duty means the engines run for long stretches, not for a few hours a year. That shifts a site into a different air permit class than standby equipment. Wyoming gets 300 jobs and a manufacturing base. The states taking delivery get the emissions and the local permitting fights.
What Happens Next
Mesa has not said how the 2 GW splits between Wyoming and San Antonio. It has not said how much of that output is already sold. The $200 million economic impact figure runs to 2030, so the company is describing a ramp rather than a full first year. Watch whether Mesa reports order backlog against the 2 GW headline. That is the number separating installed tooling from booked work.
Critical Perspective
Mesa put $70 million into a site that employs 300 people. That is about $233,000 of capital per job, which is heavy even for assembly work, and it says the money went into tooling rather than headcount. The company also projects $200 million of economic impact by 2030. That is roughly three times the build cost spread across four years, and it is Mesa’s own arithmetic rather than an audited figure. Wyoming’s economic development arm, the Wyoming Business Council, exists to court exactly this kind of plant. Mesa has not published what the state put in, and Scott Gromer credited Wyoming’s posture without naming an incentive package. What did the 300 jobs cost the taxpayer?
The 2 GW figure deserves a harder question than it usually gets. Gas gensets sell into data centers because interconnection queues run longer than construction. That is a bottleneck business. If PJM and ERCOT work through their backlogs faster than the market expects, does a 2 GW annual line still find buyers, or does Mesa hold tooling sized for a constraint that eased? The company has published neither backlog nor utilization against that number, so nobody outside Mesa is able to tell which way it is trending.
