Project Overview

The project area Is bestowed with beautiful skyline dotted by numerous peaks of the Sahyadrl hill range and a cliff on the west known as a "Konkan Kada'. It Is connected to State Highway No.44, from Shahapur, which is on Mumbai - Agra National Highway No. 3, in District Thane. The Ghatghar Pumped Storage Scheme provides for an installation of 2 reversible pump turbines, generator motor units, each of 125 MW. The scheme envisages construction of two reservoirs viz. Upper reservoir MSL 750m. The lower reservoir 0 MSL 350m. and an adjacent under ground power house.The scheme Involves recycling of water between the upper reservoir and the lower reservoir with a vertical drop of more than 400m. to generate power during peak hours and to pump water from Lower reservoir to Upper reservoir during off peak hours at night.
