Southern region of India has more peak and valley on its geological surface which leads more waterfalls. Sustainable energies are trending now due to zero emission power generation. Earth is gifted by natural energy resources every routine of time. Energy storage system for combining all the resources provides uninterrupted power supply to year around. India assures reduction of Green House Gas emissions intensity per unit gross domestic product 35% below level of year 2005, using sustainable energies in generating power to Grid. The intermittency nature of energies affects the stability of grid can be avoided by energy storage system. Energy storing system also solving the extension of power grid, increasing percentage contribution of sustainable energy in power generation, and tallying demand, and supply of energy. Technology implementing for storing power still needed more new experiments to improve the interest on development of sustainable energy generation. Pumped hydro storage is bulky potential storage technology commonly used, however power generation in low water level due to depletion of monsoon, current frequency lag for pumping and reserve spinning are achievable only by gravity hydro storage. This research technically designs and testing the proposed model of gravity hydro storage in SIMULINK analysis tool for Kadamparai location at Tamil Nadu, India. The optimum design of cylinder and piston are analyzed by ANSYS WORKBENCH also dynamic modeling analysis of hybrid sustainable energies with proposed gravity storage is done. Hybrid model with energy storage can implement in large and small hydro power houses for year around generation. This paper also suggesting model makes all abandoned mines as zero emission energy batteries.
