Combined Heat and Power – What are the Benefits?

Combined Heat and Power (CHP) systems are known to be feasible solutions for customers who are looking for a renewable energy system.

For consumers, CHP systems are able to offer optimal savings by using a single fuel system for the production of thermal energy as well as power.

These systems mix the production of electricity and heat in only one process which is extremely efficient.

In summary Combined Heat and Power (CHP) systems are:

  • Better energy efficiency
  • Cost savings
  • Generate local power
  • Fuel is neutral
  • Eco-friendly

Read on and find out more about these primary benefits of this type of renewable energy system.

Better energy efficiency

These systems trap heat which is generally wasted, and thus helps enhance energy efficiency.

Due to the use of wasted heat, CHP plants are able to attain over 80% high efficiency ratings.

This is comparable to the efficiency offered by gas power stations, which offer around 49 – 52% efficiency in the UK. In comparison, coal plants offer only about 38% efficiency.

Cost savings

It can reduce energy expenses and make business and industries more competitive. There can be around 15 – 40% savings on electricity, which comes from the grid as well as the heat that comes from boilers on site.

It can assist in reducing fuel shortage and help lower the expense of public services delivery. It can help keep expenses managed and boost the efficiency of businesses.

Generate local power!

Local electricity and heat is generated from CHP plants. In some cases, cooling is also offered to different kinds of users.

Given that the energy is locally generated, CHP offers the extra advantage of preventing loss of efficiency through distribution and transmission of electricity via local distribution networks and National Grid.

When the network itself is used for transporting energy to users from the source of generation, there is generally a loss of about 7% energy.

Once such losses are taken into account, the efficiency of CCGT and coal plants tend to fall even more during usage.

Fuel is neutral

When it comes to generating energy, CHP happens to be fuel neutral. In other words, the technique can be applied for fossil fuels as well as renewable fuels. Although the individual technologies used and the type of efficiency that is achieved will tend to differ, in all cases CHP has the power to use primary energy resources in a more effective and efficient manner.


CHP systems are able to lower the emissions of pollutants and greenhouse gases such as CO2. This in turn ensures that the Earth is greener and cleaner, with lower amount of particulate matters being released into the atmosphere.
