| Origin | What it is | Who captures it | Time horizon |
|---|---|---|---|
| 1. Import-substitution assembly | Sourcing cells and integrating them into a grid-code-compliant container | Whoever has EPC capability and capital — widely contestable | Now, but thin and increasingly price-competed margin |
| 2. Policy-subsidised volume | VGF- and ISTS-waiver-enabled tenders make low-tariff storage bids financeable | Whoever wins the SECI/DISCOM auction | Set by the government's funding calendar through 2028 |
| 3. Licensed cell manufacturing | A working Chinese or Korean technology licence, secured and kept before the access window tightened | Whoever signed early — see Exide vs Amara Raja, §9 | Now through the 2030s, but access itself is the bottleneck |
| 4. Materials sovereignty | Cathode, electrolyte and lithium-salt capacity that clears OEM/cell-maker qualification | Whoever survives the 2-4 year qualification clock (§8) | Years away — the slowest-moving, least-priced-in layer |
A 260 GWh tender pipeline dwarfs anything built so far, backed by two overlapping VGF schemes and an ISTS waiver extended to 2028. PLI-ACC's second tranche, for the first time, is explicitly earmarked for grid-scale — not EV — cells. Global battery pack prices sit at a record low, making even import-dependent Indian BESS economically viable today. And at least one Indian company, Exide, has already proven that a Chinese cell-technology licence, signed early enough, can be operationalised into a working, commissioned plant.
Nearly every other Indian conglomerate's cell-technology ambition — Amara Raja, Reliance, JSW — has stalled or been placed on hold specifically because China's technology-transfer window tightened after Exide's 2022 deal. Crisil already flags 12 GWh of under-construction capacity with weak returns because 2026 cell prices are running well above the tariffs bid in 2025. India's flagship manufacturing incentive scheme has delivered under 3% of its operational target four years in. And for most of this report's fourteen companies, storage remains too small a share of the business to be the reason to own the stock even if every part of the bull case plays out on schedule — and for at least two of the names added in a later completeness pass (Adani Green Energy, Pace Digitek), a rich valuation or an unreconciled flagship order raise real questions of their own.
