In 1952, NLC or Neyveli Lignite Corporation was being incorporated, and it is the business of lignite mining and power generation. Currently, the company operates three opencast lignite mines of the total capacity of about 24 million tonnes and the three thermal power stations, along with a total installed capacity of about 2490 megawatt. It is also a Miniratna Public Sector Enterprise, which is under the administrative control of the Ministry of Coal. And it also operates subsidiary such as NLC Tamilnadu Power Limited. It has several chequered history of achievements.

Several Mines of the Company:

  • Mine-I: It is located in the northern part of Neyveli Township in Tamil Nadu and is spread over an area of about 26.69 sq km. It also has a reserve of about 365 million tonnes and a production capacity of approximately 10.5 million tonnes of lignite p. a. It feeds lignite to its 600 MW capacity of the First Thermal Power Station and 420 MW Thermal Power Station (later expanded).
  • Mine-IA: It is spread over an area of about 11.6 sq km. and has a reserve of about 120 million tonnes with a production capacity of about 3 million tonnes of lignite p.a. Also, it caters to the need for a 250 MW independent power project, besides the needs of the NLC's Thermal Power Stations.
  • Mine-II: In February 1978, the Government of India sanctioned it, along with a lignite production capacity of about 4.7 mtpa that increased to 10.5 mpta in the year 1983. It is particularly spread over an area of about 27.74 sq km and also has a reserve of about 390 million tonnes.
  • Thermal Power stations (or TPS) TPS-I: It is the South Asia's first and the only lignite-fired thermal power station. It was being commissioned with one unit of 50 MW, and now, it possesses six units of about 50 MW each and three units of about 100 MW each. It has also set up an additional capacity of approximately 420 MW with a total generating capacity of about 1020 MW.
  • TPS-II: It is a power plant that was constructed in the two stages, such as in 630 MW and 840 MW. And it also has a generating capacity of about 1470 MW and consists of seven units, each with 210 MW.
