9. WHAT IS COMBINED HEAT AND POWER
(CHP) & TRIGEN
 CHP is a Technology where Electricity is Generated
Onsite via a Gas-Fired Reciprocating Engine , Gas-
Fired Turbine, or a Fuel Cell and the by product
waste heat in the exhaust gases is utilized to
produce the following:
 Low and High Pressure Steam for Heating and Process
Applications
 Hot Water for Heating or Domestic Hot Water
Production
 Chilled Water for Process Cooling or Air Conditioning
Applications
