India is the third largest producer of electricity in the world, behind China and the United States. In 2022–2023, India generated 1844 TWh of electricity, with 1618 TWh coming from utilities. India's per capita electricity consumption in 2023 was 1327 kWh. India plans to supplement 50% of the electricity demand through renewables by 2030. The wind, solar, and bio-power combined in India have a total penetration of 29.16% of the total grid capacity as of 31st May 2023 and 31.55% as of 30th April 2024. In the current energy scenario, India needs to strengthen its electricity grid infrastructure to accommodate the losses in inertia that will occur due to the penetration of renewables going 50% by 2030. The solution to tackle the loss of inertia is by installing grid-scale energy storage systems in the infrastructure which can provide sufficient energy to tackle the increase in electricity demand along with the loss of inertia thereby, providing flexibility to the grid operations. The primary objective of this manuscript, therefore, is to determine the minimum over-supply factor needed if three energy storage systems, viz., lithium-ion battery energy storage system, adiabatic compressed air energy storage system, and hydrogen energy storage system are installed into the grid infrastructure at the current electricity generation and demand scenario in India based on unmet demand criteria.
