Not only has this scheme supplied clean electric power to the city of Mumbai for over a century now, it has also actively engaged in the conservation of the mahseer, a fish which was on the verge of extinction and continues to be an endangered species. For over four decades now, Tata Power has successfully bred this fish in captivity in the Walwhan Lake. The hatchery breeds around 2.5 to 3 lakh baby fish each year and releases them back into the lake.
