Combined Heat & Power (CHP) Definition & Frequently Asked Questions

What is Combined Heat and Power (CHP)? Power independence with up to 80% overall energy efficiency.

Combined Heat and Power (CHP) – sometimes called cogeneration or distributed energy -- is the simultaneous production of electricity and heat from a single fuel source. CHP is not a single technology but an integrated energy system that can be modified to meet the needs of an end-user.   

Below is a simple high-level schematic of a CHP system.  

 A combined heat and power system takes water and fuel and sends it through an engine and heat recovery unit and abstracts the steam or hot water for your cooling and heating system and to run electricity for fueling your building or grid

Cogeneration equipment produces power and thermal energy from a common fuel source, generally one that is considered to be a waste product from another process.  

For more information on CHP contact your Union Gas Account Manager.

How does Combined Heat and Energy work?

Whenever a generator or any machine operates, heat is produced due to friction and other mechanical and physical interactions or chemical reactions.

The heat produced is usually not captured and utilized. The CHP concept is to capture and use that heat in addition to the power generated by the electric generator.

By designing the production of power and heat in an appropriate balance, it can maximize the cost effectiveness of the operation.

How does CHP work with your local power supply

Usually your CHP supply will work in conjunction with your power supply from the power grid to meet your energy requirements. Customers use the best combination of both to maximize their heat and power needs. Back to Top
