Sidrapong Hydel Power Station

November 10, 1897 was an epoch-making day in the power sector in India. A century back, on this day, the first hydel power station in India, and reportedly in Asia too, was commissioned at Sidrapong near Darjeeling town, the first power utility run on commercial basis for use of general public, heralding the electrical-energy-era in the Indian sub-continent, and ushering in a revolutionary change in the socio-cultural and economic life of Indian society.Quite appropriately, the Govt. of India declared Sidrapong Hydel Power Station as a 'HERITAGE POWER STATION' of India on the eve of its centenary. West Bengal occupies an unique position in the history of power development in India.
