Aiming high on the growth path

NLC at a Glance

Neyveli Lignite Corporation Limited, a “NAVRATNA” Public Sector Enterprise, under the administrative control of Union Ministry of Coal has chequered historic achievements. At present, NLC operates three Open cast Lignite Mines at Neyveli and one at Barsingsar, Rajasthan of total capacity of 30.60 million tonnes per annum (MTPA) and three Thermal Power stations at Neyveli and one at Barsingsar with a total installed capacity of 2740 MW.

On 11 April 2011, it joined the elite group of Navratna Companies. In 1956 NLC was formed as a Corporate body. NLC has a well-developed township in Neyveli in the district of Cuddalore, Tamil Nadu. It is well connected by road along the Chennai-Thanjavur State Highway and Pondicherry-Tiruchirappalli road.

All the mines of NLC are ISO Certified for Quality Management System, Environmental Management System and Occupational Health and Safety Management System. All the Power stations of NLC are also ISO Certified for Quality Management System and Environmental Management System. NLC’s growth is sustained and its contribution to India’s social and economic development is significant.


To emerge as an environment friendly and socially responsible leading Mining and Power Company and strive for operational excellence in Mining, Exploration and Power generation.


To strive towards greater cost competitiveness and work towards continued financial strength.

Unique Features of Neyveli Lignite Mines

Occurrence of Ground Water Aquifer below lignite Bed: A huge reservoir of ground water occurs below the entire lignite bed, exerting an upward pressure of 6 to 8 kg/cm2. Unless this water pressure is reduced before mining, it will burst the lignite seam and flood the Mines. This problem was overcome by continuously pumping out water round the clock through borewells located at predetermined points and thereby reducing the water pressure at the lignite excavation area. The water level is continuously monitored through observation wells for proper ground water management.

Higher Ratio of Overburden to Lignite : The overburden to lignite ratio at Neyveli Mine-I is 5.5 to 5 M3: 1 tonne. This requires huge quantity of overburden to be removed (11 T of overburden is to be removed for mining 1 tonne of lignite). High capacity excavators are used for handling large volume of overburden, after forward preparation.

Hard overburden strata : The highly consolidated overburden stratum consists mainly of Cuddalore sandstone and is hard and abrasive in nature. This problem was overcome by carrying out suitable modifications in the bucket wheel teeth and by instituting a systematic drilling and blasting programme.

Cyclonic area: The Mine is located in a predominantly monsoonal and cyclonic area. The average rainfall in a year comes to about 1200 mm and the wind velocity goes up to 160 km per hour. Every year, an Action Plan for monsoon is prepared well in advance in detail.

Research & Development

Centre for Applied Research & Development (CARD) is the in-house R&D Centre of Neyveli Lignite Corporation Limited and has been recognised by the Department of Science & Technology since 1975. The testing and R&D facilities were upgraded under a project (LERI) sponsored by United Nations Industrial Development Organisation (UNIDO), Vienna during 1995 - 2000. The main objective was to strengthen CARD to improve its capability to provide analytical, environmental monitoring, R&D, technology and services to industry and the Government. Under this project, services of national and international experts were utilised for lignite utilisation and opencast mines, power stations related problems and acquired sophisticated equipment, training and established combustion and gasification testing facilities.

Rewards and Recognition

Scope Meritorious award for Excellence

Neyveli Lignite Corporation bagged the Scope Meritorious Award for Environmental Excellence and Sustainable Development for 2011-12. This is an award instituted by the Standing Conference of Public Enterprises (SCOPE), an apex body of public sector organisations, to recognise public sector organisations which have demonstrated extraordinary skills and have made a mark in chosen fields. The company has adopted an integrated farming system, a novel method developed out of a collaborative project with the Tamil Nadu Agricultural University, Coimbatore, to reclaim the areas degraded by mining.

India Power Award

NLC also won another award for its performance in the field of Power Generation. The India Power Award 2012 instituted by the Council of Power Utilities for the largest lignite power generating company was awarded to Neyveli Lignite Corporation Limited received by B. Surender Mohan, CMD of Neyveli Lignite Corporation Limited. This award instituted in the year 2008 is to recognise the organisational/individual contribution for the development of energy sector.
