Combined Heat & Power (CHP)
What is CHP?
Combined Heat and Power (CHP) uses a single process to generate electricity and heat. The systems are usually installed on site where they are to be used, in a wide range of applications, fuels and technologies.
What are the benefits?
Because CHP systems use both fossil and renewable fuels, they bring significant environmental, economic and social benefits. Less fuel burnt means lower carbon emissions. Overall efficiencies of more than 70% can be achieved because the systems utilise the type of heat generally discarded by conventional power stations so there are bigger cost savings, typically between 15% and 40% compared to imported electricity and on-site boilers. There are fewer power losses during transmission and distribution because they are installed at point of use instead of transmitting from centralised power plants over distance, so the quality and continuity of supply can be more secure for consumers. The wide range of sizes, applications, fuels and technologies mean they can be adapted to suit most users needs, making CHP systems very versatile.
How does it work?
CHP systems usually use a steam turbine or engine to drive an alternator to generate electricity. A heat recovery boiler then uses the residual heat to produce steam for heating, cooling or industrial use.

Grants and funding
As part of the Low Carbon Building Programme (LCBP), the Department for Business Enterprise and Energy Reform (BERR) are making grants available only to those who use a certified installer and products. Grants are available for private householders, community organisations, public, private and non-profit sectors. For more information about LCBP, visit the BERR website at www.lowcarbonbuildings.org.uk
