The Chhattisgarh State was formed as per the Madhya Pradesh Reorganization Act 2000. The President of India gave his consent to this Act on the 25th August 2000. The Government of India subsequently set the first day of November 2000 as the day on which the State of Madhya Pradesh would be bifurcated into State of Chhattisgarh and State of Madhya Pradesh.
Chhattisgarh State Electricity Board was formed in accordance with the Section 5 of the Electricity Supply Act 1948 as per the Notification published in the gazette of the Government of Chhattisgarh dated 15th November 2000. Chhattisgarh State Electricity Board (CSEB) became
functional w.e.f. 01.12.2000. Chhattisgarh State Electricity Board (CSEB) has been reorganized into following five companies by the Govt. of Chhattisgarh vide Notification dated 19.12.2008 in accordance with the provisions contained in the Electricity Act 2003: 1. The Chhattisgarh State Power Holding Company Limited 2. The Chhattisgarh State Power Generation Company Limited3. The Chhattisgarh State Power Transmission Company Limited4. The Chhattisgarh State Power Distribution Company Limited5. The Chhattisgarh State Power Trading Company Limited

A
generating station which converts heat energy of coal combustioninto electrical energy is known as a steam power station.
S
team is produced in the boiler by utilizing the heat of coalcombustion. The steam is then expanded in the steam turbine and iscondensed in a condenser to be fed into the boiler again. The steamturbine drives the alternator which converts mechanical energy of theturbine into electricalenergy.

BOILERA boiler is closed vessel in which water is converted into steam by utilisingtheheat of coal combustion.Steam boilers are broadly classified into following two types:(a) Water tube boilers (b) Fire tube boilersIn a water tube boiler, water flows through the tubes and the hot gases of combustion flow over these tubes. Water-tube boilers are used for high-pressure boilers.

Superheater is a component of a steam-
generating unit in which steam, after it has left
the boiler drum, is heat
above its saturation temperature.
The amount of superheat added to the steam
is influenced by the location, arrangement, and
amount of superheater surface installed, as
well as the rating of the boiler Superheaters
are classified as convection , radiant or
combination of these.
Reheater is also steam boiler component in which
heat is added to this intermediate-pressure
steam, which has given up some of its energy in
expansion through the high-pressure turbine. The
steam after reheating is used to rotate the
second steam turbine where the heat is
converted to mechanical energy.
Steam after rotating steam turbine comes to Steam after rotating steam turbine comes to
condenser condenser which condenses the steam at the
exhaust of turbine.
It creates a very low pressure at the exhaust
of turbine, this helps in converting heat energy
of steam into mechanical energy in the prime
mover.
The condensed steam can be used as feed
water to the boiler.
In so doing, the latent heat of steam is given In so doing, the latent heat of steam is given
out inside the condenser .out inside the condenser .
The condensate water after condensation is
initially at high temperature. This hot water is
passed to cooling towers. It is a tower in which
atmospheric air circulates in direct or indirect
contact with warmer water and the water is
thereby cooled. Water, acting as the heat-transfer
fluid, gives up heat to atmospheric air, and thus
cooled, is recirculated through the system.
A chimney is a system for venting hot flue
gases or smoke from a boiler, stove, furnace or
fireplace to the outside atmosphere. They are
typically almost vertical to ensure that the hot
gases flow smoothly, drawing air into
the combustion through the chimney effect.
It is a device which removes dust or other finely
divided particles from flue gases by charging the
particles inductively with an electric field, then
attracting them to highly charged collector
plates.
An alternator is an electromechanical device that
converts mechanical energy to alternating
current electrical energy. Most alternators use a
rotating magnetic field. Any AC generator can be
called an alternator, but usually the word refers
to small rotating machines driven by automotive
and other internal combustion engines.
An turbo generator is coupled to a steam turbine
and convertsmechanical energy of the
turbine into electrical energy.
It may be hydrogen or air cooled. Rating of
turbo generator isnormally 200MW & 500MW
Switchyard is considered as theHEART of
power plant.
It is a junction , which carries the generated
power to its destination.
It is basically an open area where many
differentkind of outdoor equipments are located.
eg: busbars ,transformers , circuit breakers etc.
Switch yards can be of 400KV, 132KV.
