Looking for natural gas engines for power generation? Innio Waukesha gas engines drive generators, compressors and pumps worldwide in all manner of applications.

Waukesha engines run on all varieties of methane-based gaseous fuel, including natural gas, flare gas, landfill gas and digester gas. Power ratings range from 250 kW to 3,730 kW.

Typical uses for Innio Waukesha gas engines

They are commonly used in power generation, gas compression and mechanical drive applications.
  • Driving compressors in gas-gathering, processing and transmission operations and providing electrical power for oil and gas fields in remote corners of the globe.
  • Waukesha gas engine generator sets also can be found in landfills where they turn waste into energy; in cities where airports, hospitals and factories depend on them for peak-shaving and standby power, and in combined heat and power installations that derive maximum benefit from fuel by capturing and using engine heat for steam, hot water and chilling infrastructure needs.

History of Innio Waukesha Gas Engines


Innio’s Waukesha Gas Engine division has a legacy of more than 100 years of technological innovation. Waukesha Engine had a large range of engines running on gasoline, diesel and natural gas. These engines went into on-road and off-road vehicle applications, including a large portion of US military vehicles in the mid-20th century, and to stationary applications driving generators, compressors and oilfield pumps. In the latter part of the 20th century, Waukesha Engine narrowed its focus to stationary gaseous-fuelled engines for industrial applications – gas compression, pump drives and power generation. Waukesha Engine was acquired by Innio in 2018.

Waukesha pronunciation


We are often asked how to pronounce Waukesha: walk ashore. Just think of stepping off a boat to walk ashore. Waukesha Engine takes its name from the city in which it was formed and operates there to this day. Waukesha city is located some 15 miles west of Milwaukee, in the mid-west state of Wisconsin.
