ACKNOWLEDGEMENT
I take this opportunity to express my gratitude to everyone who supported me throughout
the course of this training. I am thankful for their inspiring guidance, invaluably
constructive criticism and friendly advice during the project work. I am sincerely
grateful to them for sharing their truthful and illuminating views on a number of issues
related to the company.
I wish to express my deep sense of gratitude to Mr. Pankaj Vashistha , who through his
benevolent guidance has enabled me to complete my project. He has been a great source
of inspiration to me all the way. Without his keen interest, incessant encouragement and
invaluable suggestions, this report could not have attained its present shape. I would also
like to thank entire NTPC staff for helping and supporting me in completing my project
work.
I would also like express my thanks to the entire shift in charges including workers and
engineers who listened to our problems and queries and helped us to sought it out. With
their guidance and advices, this training has become a memorable experience and helped
me to provide a partial insight of the industry.

ABSTRACT
NTPC is the name within Indian power sector established in 1975 with a contribution
of about 30% of Indian power sector today. NTPC is the 6th
largest thermal power
generating utility in capacity.
NTPC Limited, a premier Public Sector Enterprise of Navratna status, established in
1975 is the largest power utility with an installed capacity of 28,644 MW through 26
power stations including 4 stations operated under joint venture companies. NTPC
has emerged as an integrated Power Major with presence in Hydro Power, Coal
mining, Oil & Gas exploration, Power Distribution & Trading and also to enter into
Nuclear Power Development. NTPC contributed 15.00% of the total electricity
generated in the country during 2006-07 with 20.71% share of total installed capacity
of the nation.
NTPC Limited is the largest thermal power generating company of India. A public
sector company, it was incorporated in the year 1975 to accelerate power
development in the country as a wholly owned company of the Government of India.
At present, Government of India holds 89.5% of the total equity shares of the
