Cogeneration – Combined Heat and Power (CHP)

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
