INNIO is planning an 83,000-square-foot expansion of its 600,000-square-foot industrial facility in Waukesha.

Dubbed “Project Green,” the addition would support a new engine production line the company intends to manufacture at its West St. Paul Avenue campus, according to documents submitted to the Waukesha Plan Commission in March.

INNIO shared its plans with the Plan Commission on March 25 and discussed its plans with city staff. There was no action taken at the meeting.

Plans call for a state-of-the-art facility featuring advanced testing capabilities, as well as dedicated areas for painting, packaging and shipping operations.

“Project Green represents a substantial capital investment in the existing facility and underscores INNIO’s long-term commitment to its Waukesha campus,” Andrew Dawson, chief financial officer at INNIO Waukesha Gas Engines, wrote in a letter to the Plan Commission.

“In addition to supporting anticipated job growth, approval of this project will position the company to advance additional planned improvements to the facility that are currently under consideration. Collectively, these initiatives reflect a broader strategy of sustained growth, operational modernization, and continued reinvestment in the Waukesha community.”

City staff is in the initial plan review phase and will work with INNIO as plans are refined, a city of Waukesha spokesperson said. The project will go to the city commissions for review and approval based on INNIO’s timeline, they added.

INNIO has maintained a long-standing presence in Waukesha County, where its gas engine manufacturing operations are a key part of the region’s industrial base. The Waukesha facility specializes in the production of large-bore gas engines used for power generation and mechanical drive applications across energy, industrial and municipal sectors.

The site has undergone multiple upgrades and ownership transitions over the years but remains a cornerstone employer in the area, supporting a skilled manufacturing workforce and regional supply chain.

INNIO, which operates globally with facilities and service networks across North America, Europe and other international markets, has increasingly emphasized modernization and efficiency improvements within its U.S. footprint.
