Introduction to Co-generation
Q. So what is Co-generation?
o Theoretically it is the concept of generating two forms of
energy from combustion of one fuel
o One form of the energy must always be HEAT (i.e. Thermal)
& other may be electrical or mechanical
o It is also know as combined heat and power systems
o It is a clean & efficient source of energy generation

Co-generation
RESULT:
High cost of energy &
Its dependency over the
grid

Co-generation
Co-generation was then used for
simultaneous production of
Electricity & Heat from a single
Fuel source
RESULT:
Low cost & efficient
Energy generation

Co-generation
Q. So why use Co-generation?
o With ever increase demand for energy, sustainable ways of
energy production have to be found
o Cogeneration is thermodynamically efficient use of fuel
o In conventional methods of electricity production,
some energy must be discarded as waste heat
o In cogeneration this thermal energy is put to use
o Thus, achieving high efficiency in energy conversion

Co-generation
What are the demerits of conventional energy generation ?
o All conventional thermal power plants, emit heat during
electricity generation
o Which is released into the natural environment through
cooling towers or flue gases
o Hence lowering the overall efficiency of energy conversion

Co-generation
What are the merits of co-generation?
o Whereas in Co-generation, electricity is locally produced
o Recovered heat is re-utilized
o Surplus electrical energy can be exported to the distribution
grid
o Giving high overall efficiency & significant energy savings

Co-generation
Q. So where are Co-generation plants around us?
o In Maharashtra most of the Co-gen facilities are run by the
Co-operative Sugar Factories & Cement industries
o The sugar industry is a prime candidate for supplying
low cost, non-conventional power via cogeneration
o 623 MW of electricity is locally produced & supplied to the
state electricity board
o A typical Co-gen set up can produce from a
2(min.) to 30 (max.)MW of electricity

Types of Steam Turbines Used
o Steam turbines are the oldest prime mover technology with
capacities from 50 kW to hundreds of MWs for
large plants
o The thermodynamic cycle used for steam turbines that use
a boiler system ,is the Rankine cycle
o Most common types are
Backpressure
Extraction condensing

chilled water for
air conditioning systems
 Making industries energy self-sufficient
 No energy cost of air-conditioning also
