India’s Union Cabinet approved a Rs 1,86,405 crore (about US$19.3 billion) transmission and storage programme on 30 September, and the storage line inside it is the part that matters: Rs 50,000 crore — roughly US$5.2 billion — for 50 GWh of battery energy storage, to be built by the 2032–33 financial year. The scheme is called Green Energy Corridor Phase-III. Its job is to let the grid carry up to 135 GW more renewable power, and to put india energy storage on a footing closer to what the country’s own projections say it needs.
What the Cabinet Approved
The scheme splits into two spending lines. Rs 1,36,378 crore goes to intra-state transmission systems — the wires inside states and union territories, as distinct from the national corridors that connect them. Rs 50,000 crore goes to battery energy storage systems, deployed at the renewable developer’s end or wherever the grid needs them. Central financial support totals Rs 54,082 crore, and is intended to offset intra-state transmission charges, which is how a programme of this size is meant to avoid pushing up end-user power costs.
The delivery model is worth noting for anyone who sells into India. State transmission utilities are the overall implementing agencies. Greenfield transmission projects go out through tariff-based competitive bidding, brownfield upgrades and network strengthening are executed on a cost-plus basis, and transmission service providers participate through bidding on a build-own-operate-maintain model. In other words, the transmission half is a competitive procurement market, not a state construction programme.
The government frames the scheme as support for its target of 900 GW of installed non-fossil capacity by 2035. India crossed 300 GW of non-fossil capacity in July 2026, at which point it was more than 54% of total installed generation capacity, against a separate 2030 target of 500 GW.
India Energy Storage: 8.66 GWh Today, 236 GWh by 2032
The number that explains why this scheme exists is the gap between what India has built and what its own power ministry says it will need.

India has 8.66 GWh of large-scale battery storage and says it needs 236 GWh by 2031–32 — a 27-fold increase in six years. The 50 GWh approved here covers about a fifth of that target, which tells you two things at once: the scheme is genuinely large by emerging-market standards, and it is nowhere near sufficient on its own. Nothing in the announcement explains where the remaining 186 GWh will come from.
For scale, China ended 2025 with 136 GW and 351 GWh of new-type storage installed — about 40 times India’s battery storage base in energy terms. The comparison is not a scoreboard, because the two systems have different shapes and different starting points. It is a measure of how far behind the starting line India’s storage market still is, and how much of the country’s renewable build-out is waiting on it.
The Problem Is Not Generation
India does not have a solar shortage. It has a delivery problem, and the government’s own numbers are unusually blunt about it.
Nearly 21 GW of renewable capacity — about 9% of the installed total — is connected through temporary grid arrangements while waiting for dedicated transmission infrastructure. That gap constrains roughly 12 GW of power delivery during peak solar hours. And in the April to June quarter, when peak power demand hit a record 270 GW, grid operators had to restrict 8,133 GWh of solar generation because of transmission constraints and the need to hold the system stable. That figure came from the Ministry of New and Renewable Energy in evidence to parliament.
Put the approved storage against that waste. Fifty gigawatt-hours of batteries cycling once a day moves about 18,250 GWh a year — more than twice the solar output curtailed in a single quarter. The comparison is loose, since curtailment is a quarterly figure and the battery number is annualised and conditional on utilisation, but it establishes the argument the scheme rests on: at these volumes, storage does not compete with generation, it decides whether the generation already built can be used.
What US$104 per kWh Says About Emerging-Market Storage
Divide the storage allocation by the storage target and you get a capital-intensity benchmark. US$5.2 billion for 50 GWh works out at about US$104 per kilowatt-hour of installed battery storage.
That is a programme outlay rather than a turnkey price, so it bundles whatever subsidy structure sits behind it with the equipment and construction cost. Read it as an order of magnitude for what a government is willing to commit per kilowatt-hour of grid storage it has decided to buy. It also sets a reference point for the market that will now form around it: bidders on the storage side know the envelope, and so does every supplier watching from outside it.
The timetable matters as much as the money. The scheme is to be completed by FY 2032–33, which means the spending is spread over seven years — roughly US$740 million a year on storage, against a curve that needs 27 times the current installed base. Should the 50 GWh arrive at a steady pace rather than in a rush, the annual deployment would be in the same range as some single European markets’ current BESS pipelines.
What the Scheme Does Not Cover
Three gaps are worth flagging before anyone treats this as a complete storage policy.
No source of supply. The scheme funds deployment, not manufacturing. India has domestic cell production ambitions, but the 50 GWh in this programme is not tied to locally made cells, and nothing in the announcement describes how the equipment will be sourced or what share of it must be domestic.
No revenue mechanism. The Rs 54,082 crore of central support offsets transmission charges; it does not tell a storage developer how the battery earns money once it is running. India has been developing its storage procurement frameworks, including viability-gap support and state-level mandates, but those sit outside this scheme.
No answer to the remaining 186 GWh. The 2031–32 requirement is 236 GWh. This programme covers 50. The rest implies either a further tranche of this scheme, a substantial private build, or a revision of the target.
The Bottom Line: India’s Union Cabinet approved the Green Energy Corridor Phase-III scheme on 30 September — the largest single commitment to India energy storage so far — with a total outlay of Rs 1,86,405 crore (about US$19.3 billion) — Rs 1,36,378 crore for intra-state transmission and Rs 50,000 crore (about US$5.2 billion) for 50 GWh of battery storage, targeted for completion by FY 2032–33. India has 8.66 GWh of large-scale battery storage today and a power ministry projection of 236 GWh by 2031–32, so the scheme covers about a fifth of the requirement, at a capital intensity of roughly US$104 per kWh. The driver is not generation but delivery: about 21 GW of renewable capacity is connected on temporary grid arrangements and 8,133 GWh of solar was curtailed in the April–June quarter.
Notes: All scheme figures — the total outlay, the two spending lines, the central financial support and the FY 2032–33 completion target — are as published in the Government of India’s cabinet release and reported by Indian and international media; the US dollar conversion follows the approximate rate implied by the official figures (about Rs 96.6 per USD) and is for comparison only. The US$104 per kWh figure, the 27-times growth requirement, the 21% coverage, the 18,250 GWh annualised cycling estimate and the 40-times comparison with China are our arithmetic on published numbers; the annualised figure assumes one full cycle per day and is not a forecast of utilisation. The installed storage and requirement figures come from Power Ministry data and the curtailment and temporary-connection figures from the Ministry of New and Renewable Energy as reported to parliament, in both cases via secondary reporting rather than the underlying documents. EVsays has not verified the government’s figures independently and did not attend any briefing. See our editorial policy and correction policy.
