Distributed generation is the production of energy at its point of use. It’s cleaner and cheaper than coal-based energy, which may be transmitted across thousands of kilometres. Cogeneration or trigeneration are key distributed generation technologies and offer a total efficiency of around 85 per cent, compared to around 30 per cent for coal-fired electricity.

Cogeneration is the simultaneous production of two forms of energy electricity and heat, from a single fuel source. The most common fuel is natural gas, which burns cleanly without harmful particulates and pollutants, and only half the CO2 of coal. Biomass and biofuel waste can also be used to fuel a cogeneration system.

Trigeneration goes one step further to produce cooling as part of the process. The waste heat produced in cogeneration can be used for space heating, domestic water and pool heating, and process hot water and steam. Trigeneration converts heat into chilled water for air-conditioning and other cooling processes.

Benefits of cogeneration and trigeneration include lower cost of energy; useful heating and cooling provided for free by utilising waste heat; improved energy supply reliability and security; reduced carbon emissions and environmental impact; reduced load on the electricity network reduces the need for expensive infrastructure upgrades; and reduced transmission and distribution losses increasing overall energy efficiency.
