Combined Heat and Power

What are the advantages of Combined Heat and Power (CHP)?

  • CHP is typically over 80% efficient
  • Making typical savings of 20% on energy bills
  • Up to 30% on carbon emissions
  • Increases your fuel supply security

What types of organisation benefit from Combined Heat and Power?

To make the most of a Combined Heat and Power system your organisation needs to be using at least 5,000 hours per year of heat and power for, or a demand for power for just short of 30 weeks of the year. CHP is ideally suited to Industrial premises, Office, Hotels, Leisure centres, Hospitals and Small community heating schemes.

CHP is a highly efficient process that captures and utilises the heat that is a by-product of the electricity generation process. By generating heat and power simultaneously, it lowers carbon emissions by up to 30% compared to traditional ways to generate power using a boiler and power station together.

This short video explains perfectly how Combined Heat and Power systems work.

Is Combined Heat and Power the right thing for you?

To find out if CHP is right for you our experienced engineers will conduct a feasibility and scoping study, which will take into account site-specific issues that may affect a CHP’s suitability, as well as the basic infrastructure in place. If everything stacks up then we’ll provide you with a detailed breakdown of the overall energy and fuel savings, including forecasts of the Government incentives available and the costs for installation and ongoing maintenance.

Combined Heat and Power Technology

A CHP plant consists essentially of an electrical generator combined with equipment for recovering and using the heat produced by that generator. The generator may be a prime mover such as a gas turbine or a reciprocating engine. Alternatively, it could be a steam turbine generating power from high-pressure steam produced in a boiler. It could even be a combination of all three.

A very efficient way to generate your power

Combined heat and power (CHP) is the simultaneous generation of usable heat and power (usually electricity) in a single process. Electricity is generated on or close to your site, allowing you to capture and use the resulting waste heat for additional processes. The power generated is usually electricity, but can also be mechanical power for driving equipment such as pumps, compressors and fans.

Heat from a CHP plant can also be used to generate cooling by using an absorption chiller unit. CHP that produces heat, electricity and cooling is termed ‘tri-generation’. A site with a large and continuous cooling demand, and perhaps a declining demand for heat, may consider replacing a conventional electrical cooling system with absorption cooling. Converting an electrical load into a heat load in this way has a number of advantages:

  • Reduction in your site’s electricity demand
  • Increased options for heat use
  • Ironing out of the seasonal peaks and troughs in heat requirement.

CHP has been shown to reduce energy bills by 20-30%.

As well as reduced energy bills, CHP also offers other financial incentives, which can reduce tax liabilities, if it qualifies as ‘Good Quality’ under the CHP Quality Assurance Programme (CHPQA). As well as measuring electricity efficiency, this judges CHP schemes on something called a Quality Index (QI), which measures overall energy efficiency.

If you have Good Quality CHP, registered with the CHPQA, you can benefit from the following where applicable:

  • A reduction of exemption from your Climate Change Levy (CCL)
  • Enhanced Capital Allowance (ECA)
  • Business rates exemption
  • Preferential treatment in the Renewables Obligation (RO)
  • Preferential treatment in the EU Emissions Trading Scheme (EU ETS).

Take advantage of government incentives

Combined Heat and Power systems qualify for a whole raft of government incentives, which is one of the reasons they are so efficient to run. Our team will help you through every step of the process to ensure you make the most of these.

  • Climate Change Levy Exemption
  • Enhanced Capital Allowances
  • EU Emissions Trading Scheme
  • CRC Energy Efficiency Scheme
  • Renewable Obligation Certificates (ROCs)
  • Renewable Heat Incentive (RHI)
