Cogeneration is a high efficiency energy system that produces both electricity
(or mechanical energy) and valuable heat from single fuel source. Cogeneration is
some times known as combined heat and not only generates power but also provides
heat for industrial purposes. For example a hospital cogeneration plant would
produce some of power and all hot water needed for its laundry and hot water system
from the waste heat it generates.
Significance :
It reduces energy costs and green house gas emissions typically by upto two-third. In
addition to reduction in cost, cogeneration also increases resource utilization. It offers
major economic and environmental facilities because it turns otherwise wasted heat
into a useful energy source.
Cogeneration is a proven and reliable technology currently operating at over 100 sites
across Australia.
There is significant potential for cogeneration plants fired by other fuels, including
biomass (e.g., plant waste from sugar or cotton harvesting), or biogas (e.g., methane
produced by sewage works or piggeries).
