3. What is Cogeneration?
 Cogeneration - A process in which an
industrial facility uses its waste energy to
produce heat or electricity.
 Cogeneration is an energy-efficient,
environmental-friendly method of producing
electricity (power), steam and/or hot water at
the same time, in one process, with one fuel.

4. Cogeneration…..
 It is the use of a power station to
simultaneously generate both heat and
electricity.
 Conventional power plants emit the heat
created as a byproduct of electricity generation
into the environment through cooling towers,
as flue gas, or by other means.
 CHP captures the excess heat for domestic or
industrial heating purposes.

5. History…
 Hot-air cogeneration.
 Steam cogeneration.
 By the late eighteenth century, waste steam from
manufacturing processes was used to power
steam engines, and the hot condenser water was
used again for other process.

7. How it will help…
 Estimates are that the boiler plant is 50%
efficient at capturing heat for use around the
campus.
 Instituting a cogeneration plant along side the
boiler plant could rise that efficiency rate to
around 70-90%, thereby saving a lot of wasted
energy.

9. Need of Cogeneration.
Thermal Power Plant.
•Thermal power plants are major sources of electricity supply in India.
• In conventional power plant, efficiency is only 33% and remaining 65% of
energy is lost.
• Major loss in the conversion process heat rejected to surrounding water or
air .
• Further losses of around 10-15% are transmission and distribution .
•Through the utilization of the heat, the efficiency of the co-generation plant
can reach 90% or more.
•Co-generation therefore offers energy savings ranging between 15-40%
when compared against others.
