Power Solutions International, Inc. (PSI) designs, engineers, and manufactures advanced, emission-certified engines and power systems for a diverse range of applications. The company's business model centers on providing customized, turnkey powertrain solutions to original equipment manufacturers (OEMs) and end-users who require specialized engineering, fuel flexibility, and emissions compliance. PSI's products are engineered to run on alternative fuels such as natural gas and propane, as well as conventional gasoline and diesel.
The company operates through three primary end markets: Power Systems, Industrial, and Transportation. The Power Systems segment is a major revenue driver, supplying engines and generator sets for stationary and mobile power generation, including standby, prime, and microgrid solutions, with significant demand coming from the data center and oil and gas sectors. The Industrial segment provides powertrains for equipment such as forklifts, sweepers, agricultural machinery, and pumps. The Transportation segment supplies engines for specialized vocational vehicles, school buses, and terminal tractors. While PSI's manufacturing and corporate operations are concentrated in the United States, it distributes its products globally through OEM partnerships and channel networks. The company's competitive position is strengthened by its in-house prototyping and testing capabilities, allowing it to serve niche markets where application-specific engineering is more critical than mass-market scale.
