India’s energy transition is entering a new phase. The conversation is no longer only about how quickly the country can add renewable capacity, but about how effectively that clean energy can be delivered when the grid and consumers need it. As solar and wind become an increasingly important part of the generation mix, the next challenge is building a power system that is reliable, flexible and capable of delivering clean electricity around the clock.
This is where energy storage is becoming central to India’s energy strategy.
The transition from renewable capacity to reliable power requires a coordinated approach across demand creation, grid infrastructure, manufacturing and regulation. Policy has an important role to play in creating the conditions under which energy storage can move from being viewed primarily as a technology investment to becoming an essential component of the power ecosystem.
On the demand side, regulatory mechanisms are already helping create a stronger market for storage. Energy Storage Obligations (ESOs), Viability Gap Funding (VGF) and Firm and Dispatchable Renewable Energy (FDRE) tenders are helping establish clearer pathways for integrating storage with renewable generation. These mechanisms can improve project bankability while encouraging developers to think beyond generation capacity and focus on the availability and reliability of power.
The next opportunity lies in creating additional revenue streams for storage assets. Proposed frameworks around ancillary service monetisation and potential storage requirements for Commercial and Industrial (C&I) consumers could expand the commercial applications of battery energy storage systems. Storage can support not only renewable integration but also grid balancing, peak management and improved power quality.
This evolution is important because the economics of energy storage cannot depend on a single use case. A robust storage market will require assets to participate across multiple applications and revenue streams. Clear market mechanisms can therefore play a significant role in improving utilisation and strengthening the long-term investment case for storage.
At the same time, India’s energy transition must be supported by a resilient domestic supply chain. Production Linked Incentive (PLI) schemes are helping encourage domestic cell manufacturing, while localisation of critical technologies can reduce dependence on external supply chains over time. However, localisation should extend beyond the battery cell itself.
Control and energy management systems will increasingly become strategic infrastructure as storage deployment scales. Greater emphasis on locally developed or controlled Energy Management Systems (EMS) and Supervisory Control and Data Acquisition (SCADA) systems can contribute to cybersecurity, sovereign grid control and system resilience. As BESS installations become more deeply integrated into the electricity network, the digital layer managing these assets will be as important as the physical battery infrastructure.
The next phase of growth, however, will also depend on regulatory predictability.
Large-scale energy infrastructure projects are typically planned over long investment horizons. Developers and investors therefore need clarity not only on incentives but also on taxation, customs classifications and the treatment of different components used in storage projects. Uncertainty around the applicability of the Manufacturing and Other Operations in Warehouse (MOOWR) scheme for power projects, for instance, can complicate project planning and economics.
Similarly, clear and consistent customs duty classifications for imported battery containers, packs and cells can provide developers with greater visibility while making long-term investment decisions. Such clarity can also support India’s broader localisation objectives by allowing companies to plan the transition between imported components and domestically manufactured alternatives with greater certainty.
India’s opportunity is therefore larger than simply adding more batteries to the grid. The country has the potential to build an integrated energy storage ecosystem that connects renewable generation, grid flexibility, domestic manufacturing, digital infrastructure and industrial demand.
For this to happen, policy must continue to evolve from creating capacity to creating dependable markets. Storage needs predictable demand, multiple avenues for monetisation, a resilient domestic supply chain and a regulatory framework that gives investors confidence to commit capital for the long term.
The ultimate measure of India’s clean-energy transition will not only be the number of gigawatts of renewable capacity installed. It will be the ability to convert that capacity into reliable electricity for homes, businesses and industries, regardless of when the sun shines or the wind blows.
By aligning demand creation with domestic manufacturing, digital resilience and transparent fiscal and regulatory frameworks, India can move towards an energy system that is not only cleaner, but also more reliable, self-reliant and resilient.
The next energy leap, therefore, is not simply about generating more renewable power. It is about making clean power dependable—and energy storage will be one of the critical bridges between the two.
