Minimizing energy costs, ensuring a reliable energy supply and reducing the impact of energy use on the environment are all important considerations for companies and organizations today. For over a century, organizations across the globe have used combined heat and power (CHP), also known as cogeneration, as a strategy to provide reliable electricity, steam, hot water and cooling with lower cost and emissions than grid-supplied electricity and an on-site boiler.
 
CHP has always been a good fit for large applications with electricity and heating demands including in chemical plants, universities and food processing facilities. But now new developments have made CHP an attractive option for smaller applications (e.g., office buildings, multifamily residential buildings, supermarkets and hospitals). And for organizations seeking US Green Building Council LEED green building program certification, CHP can significantly improve the LEED score a building will achieve.
