India’s Battery Storage Sector Set for Massive 91% Growth by FY32
India's Battery Energy Storage System (BESS) sector is set for a massive 91% CAGR, reaching 302GWh by FY32, according to a new Nuvama report.
India is on the verge of a massive transformation in its energy infrastructure, with the Battery Energy Storage System (BESS) sector projected to witness an explosive compound annual growth rate (CAGR) of 91 per cent between FY26 and FY32E. According to a recent report by Nuvama, this surge is essential to support the country's renewable energy integration, grid balancing, and the rising demand for round-the-clock power.
The report highlights a dramatic shift in capacity, forecasting that cumulative storage will leap from a mere 6.3GWh to a staggering 302GWh over the specified period. Annual additions are expected to climb from 5.7GWh in FY26 to 56GWh by FY32E.
A Long-Term Vision for Energy Security
The scale of required expansion is immense. The Central Electricity Authority (CEA) estimates that national demand for BESS will reach 236GWh by FY32, with a long-term requirement of 1,840GWh by 2047. Currently, India relies heavily on external sources, with 89 per cent of its requirements being met through imports.
However, several factors are poised to accelerate domestic adoption and localisation:
- Falling Battery Costs: Decreasing prices are making large-scale storage more viable.
- Regulatory Frameworks: The potential implementation of an ALMM-like framework could boost domestic capacity.
- Technological Shifts: While Lithium-ion currently dominates 98 per cent of the market, there are significant opportunities in sodium-ion technology and the "China+1" global supply chain theme.
Manufacturing Economics and Profitability
The report dives deep into the financial landscape of battery manufacturing, noting that different end-markets offer distinct profit margins. The commercial, industrial, and retail segments are expected to yield spreads of USD 18 to 23 per kilowatt-hour, resulting in EBITDA margins between 17 and 20 per cent.
In contrast, the utility segment—while crucial for the grid—operates on tighter margins, with spreads of USD 8 per kilowatt-hour and an EBITDA margin of approximately 9 per cent. Despite these lower margins, channel checks suggest a quick one-to-two year payback period for utility-scale investments.
The Edge of Domestic Production
Local manufacturing holds a significant competitive advantage. The report notes that domestic production benefits from:
- Lower Capital Expenditure: Estimated at USD 80 million per gigawatt-hour.
- Government Support: Production-linked incentive (PLI) support of Rs 181 billion for 50GWh.
- Competitive Costs: Favourable labour expenses compared to global peers.
Furthermore, while an integrated BESS facility might offer a modest internal rate of return (IRR) of 12 per cent, cell-to-pack configurations demonstrate a much higher IRR of 31 per cent. With the right policy support and scale, integrated BESS could even turn India into an export hub.
Financial Impact on Listed Players
For companies in the solar and storage space, BESS integration is expected to become a major revenue driver. By FY28, BESS could contribute anywhere from 17 to 60 per cent to total company revenues. The report specifically mentions that companies like Premier could see BESS representing 60 per cent of their projected FY28 revenue, while Vikram is positioned for a 54 per cent revenue uplift.
Despite this potential, the report observes that most listed solar and BESS players have yet to see their earnings truly reflect these massive contributions. Currently, solar/BESS stocks are trading at a significant discount compared to battery chemical and battery IPP peers. As capacity begins to ramp up, BESS is expected to emerge as a powerful driver for earnings upgrades and valuation re-ratings across the sector.
