Cummins, powered by Capstone microturbine

Permanently mounted microturbine designed for customers who want to run a generator a high number of hours or power their site around the clock, have access to free or “dirty” fuel, such as a gas well or digester-based fuel, or have high electricity rates or extremely unreliable power. Capstone will supply engine components, and Cummins will put up generator enclosure and sell the generators through its network of distributors and dealers.

Size: 30- or 60-kW machines that can be linked in an array of 20 units to provide from 30 kW to 1.2 MW

Fuel type: Natural gas, propone and diesel

Competitive edge:

  • Can run for long periods of time between routine maintenance checks and services because you don't have to change the oil.
  • The low-pressure combustion engine is able to make use of less refined fuels.
  • Good service support, with 31 distributors in North America and more than 200 branch locations.
  • Wide range of product offerings in the farm market, including a full line of reciprocating-engine generator sets in addition to microturbines, plus after-treatment systems for its diesel and gaseous fuel sets. Products run from 4 to 2,000 kW.

One-stop shop for all power-generating electronics and parts.

Suggested list price: two-and-one-half to three times that of a comparably sized reciprocating-engine-based generator set (fueled by diesel or natural gas).

Competitive edge:

  • Engine and generator are matched to take out the spec and size guesswork and simplify the permit process.

  • Can run on a variety of fuels to limit emissions and make it easier to get a permit than with a generator with a diesel engine.

  • Package uses smaller power cylinders and a smaller engine that run at higher speeds and create more horsepower in a smaller package than traditional large natural gas generator sets do to improve fuel consumption, lower emissions and lower customer's packaging cost.

  • Comes in 6-, 8-, 12- and 16-cyl. models. All have common bore-in stroke and many interchangeable components for use on other Waukesha engines.
