Combined Heat and Power
CHP Plant based on gas engines

The process of transforming the energy from any source into electricity is never loss-free. In thermo electrical generation, 50% or more of primary energy is lost, most of it transformed to heat that is usually wasted (Waste Heat)

Combined Heat & Power (CHP) is a technique used to obtain both electricity and useful heat from a single energy source. This is accomplished by using the heat generated inevitably in the electrical generation process to satisfy a local demand of thermal energy (hot/cold water, steam, hot air…) instead of wasting it. With CHP Wasted Heat is turned into Useful Heat.

CHP Benefits:

  • Increase the energy efficiency and therefore produces significant savings in primary energy. The fuel consumption is lower when used to produce both electricity and heat simultaneously (CHP) than when is used to produce them separately (Conventional Generation)
  • Reduction of emissions of greenhouse gases, particularly CO2, Kyoto Protocol friendly Technology.
  • Due to the fact that CHP is Distributed Generation, it leads to lower transport and transformation losses in the network, and less electrical infrastructure requirements

The most suitable industrial sectors that can take advantage of CHP benefits are those with high thermal demand such as:

  • Ceramic Industry
  • Waste Water Treatment
  • Chemical Industry
  • Steel.
  • Wood Industry
  • Asphalt Industries.
  • Pulp and Paper Industry.
  • Dairy Industry
  • Food Industry
  • Shopping Centers.
  • District Heating and Cooling Networks
  • Hotels and Resorts.
  • Health Care Industry
