ABOUT B.T.P.S

Barauni Thermal Power Station is an existing 320 megawatt coal-fired power station owned by Bihar State power generation company limited (BSPGCL).

The power station is located at Begusarai district, Bihar, India.

Barauni thermal power station in Bihar came into existence in association with the Russian collaboration in the year 1962.

coal is supplied from Rajmahal coal field

and Urma Pahari tola,Jharkhand.Currently two new units VIII and IX are

under construction which will increase the power output by 500MW.

The equipments are supplied by BHEL , Bhopal.

The electricity generated here is sold to North Bihar Power Holding company Ltd.

GENERATION UNITS AT B.T.PS

There are total seven units in B.T.P.STwo units are currently working producing total o/p

of 220 MW.Unit no. V and VII are undergoing renovation and

modernization.The capacity of plant will be increased to 500 MW

in next 5 years.

Thermal power plantA generating station which converts heat energy

of coal combustion into electrical energy.

condenser

It condenses steam at exhaust of turbine.It creates very low pressure at the exhaust of

turbine which helps in converting heat energy of steam into mechanical energy in prime mover.

The condensed steam can be used as feed water to the boiler.

turbinesIt is used as prime mover to generator.Three types of turbine are used : 1.HP turbine 2.IP turbine 3.LP turbine

Electrical equipments

Generator : To generate electricityTransformer : For required voltage Switch yard : Onward transmission of powers

Why coal as a fuel

Coal can provide usable energy at a cost of between 12 to 15 % compared to oil and natural gas, and coal prices are relatively stable.

Coal is inherently higher polluting and carbon intensive than other energy alternatives. However coal is so inexpensive that one can spend quite a bit on pollution control, and still maintain coal’s competitive position.

observations

B.T.P.S has a very good working environment.B.T.P.S is very sincere about cleanliness and

hygiene.It has got a Technical training centre with very

good learning environment.Staff is excellent and supportive and always

ready to help.

conclusion

It is third largest thermal power plant of Bihar.It generates 210 MW electricity and after

completion of extension project it will produce 500 MW electricity.

It is major contributor of electricity to 7 districts of north Bihar.
