Energy savings and resource efficiency


Cogeneration and trigeneration

Cogeneration, or combined heat and power (CHP), is the simultaneous production of electricity and heat from a single fuel source – commonly, natural gas. Trigeneration is an extension of cogeneration that involves the simultaneous production of electricity, heating and cooling.

The benefits of cogeneration

  • improve environmental ratings (NABERS and Green Star)
  • reduce primary energy costs by up to 60 per cent
  • reduce greenhouse gas emissions by up to 66 per cent
  • increase security of energy supply
  • increase fuel efficiency.

Feasibility guide and tool

We have developed a guide to help you understand cogeneration and trigeneration, and the steps you need to take to determine the feasibility of a system at your site.


Our tool, to be used with the guide, allows you to input your site's energy and tariff data to help you make an informed decision about the financial viability of cogeneration.

Cogeneration feasibility training

We have  introductory and technical training courses so you can learn more about cogeneration.
