Bhira, located about 150 km from Mumbai, was the third hydropower plant installed by The Tata Power Company Ltd. (TPCL) in 1927. Bhira power station with a 6 x 25 MW generating units (double overhang Pelton turbines), along with other hydro and thermal power stations forms a vital link in sustaining the industrial activity of Mumbai-Pune region of Maharashtra state. Realizing the crucial importance of peaking assistance to the grid, Tata Power had installed a pumped storage unit as an extension to the existing Bhira hydro power station. The Bhira pumped storage unit is the single largest such unit in India and is perhaps the only pumped storage unit operating in both pumping and generation mode in India at the time of its commissioning.
