The Government of India plans to integrate 175 GW of variable renewables into the grid by 2022. At the same time, India's power consumption is steadily increasing. Hence, to ensure energy security and better utilisation of intermittent renewable generation, energy storage systems at the grid-scale are required. There is a range of grid-scale storage options, which can be incorporated in the Indian power grid.
In this article, the authors analyse the different energy storage systems, their applications in the grid and key policy recommendations on the suitability of energy storage in the grid. The key policy recommendations include the use of energy storage system as a generation, transmission, distribution, and end-user asset.
