The Neyveli New thermal power project (NNTP) is a 1GW lignite-fired power station located in India's southern state Tamil Nadu. Neyveli Lignite Corporation (NLC India), a public enterprise under the Ministry of Coal, Government of India, constructed the facility with an estimated investment of approximately £870m ($1.3bn).
States has far more coal than gas and petroleum (compare Figures 7-1, 8-1 and 9-1). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal as our major fossil fuel energy resource. How long could we rely on domestic supplies of coal? There are many uncertainties involved in making such an ...

The nature of coal is such that the higher the carbon content, the more cleanly and brilliantly the coal burns. Thus ―peat‖, which is the state of the decomposing plants before being compressed, is a weak, impure substance. The other states of coal from lowest carbon content to highest are lignite, bituminous coal, and anthracite coal.
