Efficient on–site power systems that produce electric power and thermal energy for heat, steam or air conditioning while reducing greenhouse gases.

Cogeneration, or combined heat and power (CHP), is the production of two kinds of energy – usually electricity and heat – from a single fuel. Systems can be powered by either natural gas or diesel. They typically involve a reciprocating–engine generator that produces electricity and a heat–recovery system to capture the waste heat from the engine’s exhaust and cooling system.

By capturing and using the waste heat, these systems consume only 50 percent of the fuel burned by a central power station to provide an equivalent amount of energy. Since greenhouse gas emissions are directly related to the amount of fuel burned, CO2 production is also cut in half.

Economical cogeneration systems based on reciprocating–engine generators area available from as small as 30 kW to more than 100 MW. By making continuous use of both electricity and thermal energy, customers can save up to 35 percent on overall energy costs.

Other benefits include:

  • Improved reliability of your electric supply
  • Easy system installation and expansion
  • Eligibility for CHP tax credits
  • Eligibility for “carbon credits” for reduced CO2 emissions

  • PDF icon De Breuck Greenhouses – Belgium (181kb)

    Geert De Breuck produces about 1,650 metric tons (3.64 million pounds) of tomatoes annually with the help of a cogeneration (combined heat and power) system designed by Cummins Power Generation that generates electricity for on-site use and for sale to the power grid, while simultaneously producing heat and carbon dioxide for plant growth.

  • PDF icon INDITEX Group Logistics Centre – Spain (254kb)

    Cummins Power Generation’s 2.3 MW natural gas powered cogeneration (combined heat and power) plant supplies hot water, low pressure steam and cooling to the entire distribution centre optimizing building operations, improving energy performance while also reducing CO2 emissions.

  • PDF icon Jinqiao Sports Center – China (188kb)

    Visitors to Shanghai’s Jinqiao Sports Center can work out in comfort, thanks to a cogeneration (combined heat and power) system from Cummins Power Generation. The cogeneration system uses natural gas to power an on-site electric generator set that supplies electricity to the facility, while the waste heat from the engine is used to make hot water and heat the swimming pool and building.

  • PDF icon Pastas Doria – Colombia (196kb)

    Pastas Doria, a large Columbia based manufacturer of pasta products, turned to Cummins Power Generation for a solution to reduce their high energy and fuel costs. The cogeneration (combined heat and power) system runs 24 hours-per-day, reducing is electricity purchases by 60 percent and fossil fuel purchases by 70 percent.

  • PDF icon Western Milling – United States (186kb)

    With rates soaring for both electricity and natural gas in Southern California, Western Milling, a large animal feed supplier, decided it needed to do something to reduce its energy costs. Cummins Cal Pacific, the local distributor for Cummins Power Generation, analyzed Western Milling’s need for more economical energy and recommended a cogeneration (combined heat and power) running on natural gas.

  • PDF icon William Floyd School District – United States (145kb)

    William Floyd School District saves money on high on–peak electric rates at their Shirley, New York campus with a cogeneration (combined heat and power) system from Cummins Power Generation. The system provides the school district with the most cost–effective, low maintenance and user–friendly solution to generate nearly all of the electricity, heat and cooling during the local utility’s daily peak usage hours.
