Energy storage is an essential part of grid modernization and decarbonization, both essential for economic and social development in India. Unlike any other grid technology, battery-based energy storage like AES India and Mitsubishi Corproration’s 10 MW energy storage project in Rohini – the first such asset in India – stores electricity and can then deliver it within milliseconds, reducing instability on the electric grid and capturing more energy to be delivered on demand. India’s need for and interest in energy storage and renewables+storage pairings is evidenced by the recent record-setting 1.3 GW procurement by Solar Energy Corporation of India (SECI) for firm power. Int that procurement, battery-based energy storage proved cost-competitive with other types of storage – notably pumped hydro – to firm solar and wind output.

Recent reports from India’s central electricity regulator and the Rocky Mountain Institute point to an immediate need of 3-5 GW of fast-response resources like energy storage to regulate frequency across the nation. Given the high amount of solar coming online and the accompanying need for flexible resources to support the evening ramp-up of electricity demand, resources like storage will become even more critical over the coming years. For example, The AES Corporation estimates the market size for storage in India to reach USD $50 billion in coming years.

Energy storage is a crucial tool for enabling the effective integration of renewable energy and unlocking the benefits of solar and wind power for emerging market. India is expected to be one of the largest energy storage markets in the coming decade. A recent report suggested that energy storage installations around the world will multiply exponentially to reach a capacity of 1,095GW/2,850GWh by 2040.

Launch of National Mission on Transformative Mobility and Battery Storage in 2019 will provide a roadmap to help reduce India’s oil import dependence and enhance the uptake of renewable energy and storage solutions. Budget 2020 has further provided impetus to the sector.

Storage will see a convergence with solar and energy management for commercial and industrial customers. Greater adoption will be led by exponentially reducing cost of Li battery and customer’s push to attain energy independence and offset its reliance on diesel consumption.
