Why India needs grid-scale battery storage

What’s the need for battery storage?

Large battery storages that store and reconvert electricity can help India’s electricity grids, given the intermittent nature of power from clean energy sources such as solar and wind. India already has 100 GW of solar and wind capacity, and is adding another 63 GW. A planned renewable capacity of 450 GW by 2030 can threaten the grid’s stability in case of generation outages due to cloud cover, rains, or wind dying down affecting renewable energy production. Large grid-scale battery storage can help in such a scenario, ensuring the grid frequency remains in the range of 49.9–50.05 hertz (Hz).

What are the steps taken in this respect?

India has unveiled an ₹18,100 crore production-linked incentive (PLI) scheme for a battery storage eco-system that involves setting up 55-GWh manufacturing capacity for advance chemistry cell batteries. The Centre plans to call bids for setting up around 4 GWh of grid-scale battery storage system at the regional load dispatch centres.

NTPC has floated a global tender for a 1GWh grid-scale battery storage system and Tata Power Solar has been contracted to set up India’s first large-scale battery storage of 50 megawatt-hour (MWh) at Leh. Reliance Industries Ltd has plans to set up an advanced energy storage giga factory.
