Combined Heat and Power (CHP)

Definition Benefits of CHP ü Cost savings from higher net

efficiency

ü  Beneficial use of local energy resources

ü Reduces CO2 emissions

ü  Aids in recovery from grid disturbance

ü  Alleviates T&D congestion

Combined heat and power (CHP) is the concurrent production of electricity and useful thermal energy from a common fuel source.

CHP systems help commercial and industrial businesses, municipalities, and a wide range of institutions get the most out of their plant and transmission and distribution (T&D) investment.

Proven, reliable and cost-effective technology

• More than 9,000 of GE’s cogeneration plants have been delivered around the world with an overall electrical output of ~11,000 MW.

• The GE fleet of gas engines produces in excess of 66 million MWh of electricity and 60 million MWh of heat annually – enough to power about 3.6 million US homes and heat about 5 million US households.

• This deployed fleet also reduces CO2 by 4 million tons – the amount of emissions from about 800,000 US cars per year.
