Cummins Power Generation is a worldwide supplier of generator sets and related services. Cummins Power Generation brand products include power systems and related accessories, components and services including the pre-integrated PowerCommand system, plus diesel and natural gas generator sets, transfer switches, and switchgear used in commercial facilities for emergency backup and prime power.

Lean–burn gas generator sets are designed to provide reliable performance, high fuel efficiency and very low emissions for applications such as high–hour peaking, prime power and combined heat and power (CHP). Running on a lean mixture of fuel and air, this design significantly reduces the production of nitrogen oxides (NOx) and increases fuel efficiency. The result is a generator set with a high power output, maximum thermal efficiency and NOx emissions as low as 0.7 grams per brake horsepower–hour.
