Combined Heat and Power (CHP) Definition and 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.
