The presence of lignite in the area was discovered by C. Jambulingam Mudaliar when he dug borewell in his land for irrigation. The water which emerged was black in colour so he asked the erstwhile madras presidency to conduct the necessary experiments for the reason of black colour of water. He donated his land to the then government free of cost when the reason was detected to be the presence of lignite for its utilisation in power generation, for the benefit of people.[6]
