 This is possible by installing Water Powered Pump (WPP) units at the base of the dam.It is technically feasible to generate power by the existing hydro turbines from lower head (75 to 50 meters) at lower frequency and the lower frequency power can be upgraded / converted to normal grid frequency (50 Hz) by installing HVDC converters before feeding power into the grid.The unused converter stations of HVDC Sileru–Barsoor transmission link can be relocated and utilised for this purpose.
