Barh Super Thermal Power Project
NTPC is one of the dominant players of the India’s
power sector. India is facing supply side constraint on the
power front. NTPC, formed in 1975 to accelerate power development
of the country, with the Government of India holding almost
90 per cent of the company's total equity shares is holding
forte on the power front. As per the latest estimate released
in April 2008, the company has contributed 28.51 per cent
of the total electricity generated in the country during 2007-08
with 19.11 per cent share of the total installed capacity
of the nation. The company boast of the current installed
capacity of 29,144 MW, including 1794 MW from JVs. The company
aims to add more than 10 GW in new coal-fired plants by the
end of the eleventh plan i.e., by 2012. The approved outlay
for 2008-09 for capital schemes of NTPC is Rs 1,35,880 million.
The company shall generate 2,09,000 MUs of electricity in
the financial year 2008-09. One of the most promising project
of NTPC is Barh Super Thermal Power Project.
Barh Super Thermal Power Project:
This project was approved by the Central Electricity Authority
(CEA) way back in the year 2001. The project funding is through
domestic and external commercial borrowings, with equity from
internal resources of NTPC. The project is accorded mega power
project status, based on which it is eligible for certain
benefits such as no customs duty on import of capital equipment,
and price preference of 15 per cent for domestic public sector
Stage - I: The first stage consisting of three units of 660
MW each is under implementation. The contract for construction
of Barh Super Thermal Power Project - Stage I was awarded
to Technopromexport a Russia-based power equipment supplier,
upon the results of open tender, held by NTPC in November
2004. The contract value was USD 454 million. The group designed,
manufactured, supplied, erected and commissioned the three
power units for the turbine island. The pump set consisting
of 9 turbine or electric driven feed pumps and 9 condensate
pumps are being supplied by the KSB Group since April 2007.
In this project, Yokogawa India is providing instrumentation
systems for the boilers and other utilities of three power
generators. These include the CENTUM CS 3000 R3 Distributed
Control System, PRM Plant Resource Manager, DPharp EJA Pressure/Differential
Pressure Transmitters, and IR8A Infrared Gas Analyzers. As
part of its full turnkey project solution, Yokogawa India
is also providing engineering, installation, and commissioning
services. This contract is estimated to be worth USD 11.8
Stage - II: The company plans to spend about Rs 7,341 crore
for setting up the second phase of Barh super thermal power
project in Bihar. The company board has accorded the investment
approval for Barh Super Thermal Power Project, Stage-II (2
X 660 MW) in Bihar at an appraised estimated current cost
of Rs 7,341 crore.
Technology in use: The plant uses super-critical steam generation,
with water instantly being converted into steam without passing
through the boiling phase. Operating pressures are around
250 atmospheres. Fuel requirement: The annual coal requirement
for Barh will be met from the Amrapali block of North Karanpura
coal fields. The coal would be transported by using rail network
from North Karanpura to Barh. The power generated will go
mostly to North, West and East India. Six 400KV electrical
substations link Barh to Kahalgaon, Sasaram and Biharsharif.
This project will go a long way in solving energy crisis in
Bihar. As per CEA report released in April 2008, there is
a energy deficit of 14.2 per cent for the period April - March
2008 (See table). It is 26.8 per cent for March 2008 alone.
The peak demand for March 2008 was 1534 MW against the supply
of 1020 MW, thereby resulting into a power deficit of 514
MW amount to 33.5 per cent peak hour deficit in Bihar.

NTPC's core business is engineering, construction and operation
of power generating plants. It also provides consultancy in
the area of power plant constructions and power generation
to companies in India and abroad. The company plans to be
a 50,000 MW plus Company by 2012 and 75,000 MW plus Company
by 2017. As on date the installed capacity of NTPC is 29,144
MW through its 15 coal based (23,395 MW), 7 gas based (3,955
MW) and 4 Joint Venture Projects (1,794 MW). Currently 16,930
MW projects are under construction.
3300 MW (1980 MW - Stage I, 1320 MW - Stage II)
Stage-I: Rs 19,000 Crore
Stage-II: Rs 7,342 Crore
NTPC has recently tied a loan of USD 380 million (approximately
Rs. 15272 million) with international banks under Japan aBank
of Cooperation (JBIC) guarantee to part finance the 1980 MW

State-owned power equipment manufacturer Bharat Heavy Electricals
Ltd (BHEL) has been awarded Rs.18-billion ($450 million) contract
to supply boiler package to the National Thermal Power Corporation's
1,320 megawatt (MW) Barh stage-II supercritical power project
in Bihar. The entire project is expected to complete by March
Clean coal technologies
Power generation in India is largely dependent on coal. The
targetted capacity for the XIth plan is 78,577 MW, out of
which around 46,600 MW is expected from coal based power projects.
The use of coal causes environmental problems. To address
these environmental concerns, India has adopted clean coal
technologies for power generation. Some of these technologies
in use are given below:
In India supercritical units of 660 MW are under installation
at Sipat and Barh Thermal Power Stations(TPS) of NTPC Ltd.
Ultra Mega Power Projects are also envisaged to be with supercritical
parameters. Supercritical generating units are being manufactured
by a number of countries viz, USA, Japan, Germany, Korea,
Russia, China etc. BHEL has also on-going collaboration for
manufacture of supercritical boilers and turbine generators
with M/s Alstom and M/s Siemens respectively. L&T has
also formed a joint venture company for manufacture of supercritical
boilers and turbine generators with MHI, Japan.
Circulating Fluidised Bed Combustion (CFBC) Technology
Four CFBC units of 125 MW each are operating at Surat lignite
TPS and Akrimota TPS in Gujarat. Six CFBC units of 125 MW
each are under execution at Surat Lignite, Giral TPS and Barsingsar
TPS. CFBC units of 250 MW are being installed at Neyvelli
by Neyvelli Lignite Corporation. CFBC boilers are already
being manufactured in India.
Integrated Gasification Combined Cycle (IGCC)
So far the world over, IGCC technology has been adopted for
low ash coal which is not suitable for Indian high ash coal.
In India, efforts are underway to develop this technology
through indigenous efforts.
