Combined Heat and Power (CHP)

Combined Heat and Power (CHP)

CHP currently accounts for less than 10% of UK electricity generation but has been identified for significant growth by the UK government given its well established characteristics of carbon reduction and cost effectiveness. 

Additionally, technological developments have greatly improved efficiencies over the last 10 years. This has dramatically increased the number of buildings that profit from this exciting technology. Traditionally CHP systems were large, offered little variation in output and were frequently coal fired.   Heat was delivered by large networks of district heat main pipes which often lost a significant amount of heat.

Modern CHP systems include many low output appliances which are installed much closer to and often inside consumer buildings, usually in conjunction with conventional boilers.  They can also be integrated with heat pumps and biomass boilers.  Compact design and low noise levels mean systems are often installed in conventional plant rooms.

The basic premise is generating electricity on site, with heat as a ‘free’ by product.  Therefore CHP systems are most appropriate for organisations with a high base load of both electricity and heat.  Cost savings are derived from:

  1. Primary fuels being much cheaper to deliver to site than grid supplied electricity owing to relatively low pipeline or haulage costs.
  2. The absence of thermal losses in the generation of conventional fossil fuel based electricity.  Instead careful design ensures that the cooling function the CHP engine requires is  met by the buildings heat distribution system.
  3. State of the art technology allowing systems to modulate down to 40% of nominal output thereby capturing a large proportion of a buildings electrical demand.
  4. Efficient heat network design capitalising on experience across Europe over the last 40 years.

Glendevon Energy’s primary focus is small scale natural gas fired CHP (<500kW electrical and <1MW thermal demand).  This is ideally suited to the Hotel and Leisure Sector, Care Homes, Food and Drink producers, Educational Establishments and large domestic properties.  State of the art systems can be monitored remotely and have service intervals of up to 10,000 hours.
