Combined heat and power (CHP) systems provide on-site electric power, heating and cooling from a single fuel source. This efficient power generation technology is also called cogeneration.
Conventional power generation plants create heat as a byproduct and expel it as waste into the atmosphere. In contrast, CHP systems recover that waste heat and use it to operate industrial processes, heat domestic hot water, and provide space heating and cooling.
Common CHP equipment includes reciprocating engines, microturbines, steam turbines, and gas turbines. Typical CHP customers include industrial, commercial, institutional, and multifamily facilities.
Benefits of CHP
The use of CHP systems is growing at a rapid pace because of increasing demands for energy efficiency, operating flexibility, resiliency, and reduction in fuel use and harmful emissions.
CHP is more fuel efficient than centralized power generation because CHP recycles valuable heat and produces power where it is used, so power is not lost during transmission over large distances.
CHP systems are designed to operate every day to save energy and money. Because they operate every day, CHP systems are proven to be more reliable than traditional emergency back-up generators during grid outages. This resiliency makes them popular with multifamily buildings.
CHP systems can produce electricity and heat during a grid outage. This benefit is especially important for critical facilities like nursing homes and hospitals.
Increasing fuel efficiency also decreases emissions of environmental pollutants such as CO2, SOx, and NOx. These pollutants have been linked to global climate change, acid rain, and other forms of environmental damage.
Installing CHP Systems
To maximize benefits, CHP systems must be properly sized for the buildings they serve. Learn more about how NYSERDA can help you evaluate your options, and get a CHP system installed in your facility.
