India is preparing a policy framework to support long-duration energy storage systems under a broader strategic roadmap titled “India Battery Storage Vision 2047”, reflecting the government’s increasing focus on solving renewable energy intermittency and strengthening grid resilience as clean energy capacity expands rapidly. According to a report, the proposed support mechanism is being jointly developed by the Ministry of Power and the Ministry of Heavy Industries.

The policy initiative comes at a time when India’s renewable energy buildout is accelerating faster than transmission and storage infrastructure. India has added nearly 178.88 GW of renewable energy capacity over the last five years, pushing clean energy’s share in installed power capacity to over 51%. However, the rapid rise of solar and wind energy has also exposed a structural weakness in the power ecosystem renewable generation is inherently intermittent, while electricity demand remains continuous.

This is where long-duration energy storage systems become strategically important. Unlike conventional battery setups designed for short bursts of power balancing, long-duration storage technologies are intended to store electricity for extended periods, often several hours or longer. These systems can help stabilise grids during peak demand, improve renewable integration, reduce curtailment of solar and wind power, and lower dependence on fossil-fuel-based peaking plants.

The government’s proposed incentive model appears aimed at accelerating commercial viability in a sector where costs remain elevated and deployment is still at a nascent stage in India. Policymakers are increasingly recognising that renewable capacity additions alone may not be sufficient to meet India’s long-term decarbonisation and energy security targets unless supported by reliable storage infrastructure.

The proposed Battery Vision 2047 framework also fits into India’s broader industrial strategy around localisation of advanced energy technologies. Over the last few years, the government has already introduced Production Linked Incentive (PLI) schemes for advanced chemistry cell manufacturing and has attempted to position India as a future battery manufacturing hub. The new storage-focused roadmap could deepen that policy direction by extending support beyond manufacturing into deployment and grid-scale utilisation.
