Battery-cell PLI stuck near 1 GWh of capacity

India's flagship incentive to make advanced battery cells at home has awarded 40 GWh on paper, but only about 1 GWh is actually installed against a 50 GWh goal.

What happened

• The Ministry of Heavy Industries reported the cumulative manufacturing capacity built so far under the National Programme on Advanced Chemistry Cell (ACC) Battery Storage — the Production Linked Incentive (PLI) scheme for battery cells.
• The scheme was approved in May 2021 with an outlay of ₹18,100 crore, with the stated objective of establishing 50 GWh of domestic ACC manufacturing capacity.
• Against that 50 GWh target, capacity for 40 GWh has been awarded to four firms; of this, only 1 GWh has actually been installed so far.
• The single installed gigawatt-hour sits with Ola Cell Technologies, which holds a 20 GWh award.
• The release plainly records that domestic demand for cells is still met largely by imports, and that the bidders are deploying their own in-house ACC technology rather than licensed foreign cell chemistry.
• In effect, this is the government itself flagging a build-out gap: a large committed incentive, a clear capacity goal, and a thin slice of capacity on the ground four years in.

Background & context

An Advanced Chemistry Cell (ACC) is the new generation of energy-storage cell — the rechargeable electro-chemical unit (most commonly lithium-ion today, but the scheme is deliberately chemistry-agnostic) that stores electrical energy and discharges it on demand. ACCs are the heart of an electric-vehicle (EV) battery pack, of grid-scale storage that firms up solar and wind power, and of consumer electronics. India consumes a rising volume of these cells but, until recently, manufactured almost none of them — the cells were imported and only assembled into packs domestically. The strategic worry is plain: an energy transition built on imported cells simply swaps an oil-import dependence for a cell-import dependence.

The ACC-PLI was the government's answer. It belongs to the wider family of Production Linked Incentive schemes launched from 2020 onwards across 14 sectors — from electronics and pharmaceuticals to white goods, specialty steel, textiles and automobiles — under which the Centre pays a manufacturer a cash incentive calculated on its incremental sales of goods made in India, rather than handing out an upfront capital subsidy. The logic is output-linked: you are paid only after you produce and sell, which is meant to reward firms that actually build capacity and scale it. The ACC programme is administered by the Ministry of Heavy Industries, the same ministry that runs India's EV-demand schemes, so that the supply side (cells) and the demand side (vehicles) sit under one roof.

The scheme sits alongside, but is distinct from, the automobile and auto-component PLI and the EV-demand schemes the same ministry runs. On the demand side, the Ministry of Heavy Industries operates the PM E-DRIVE scheme (the successor to FAME-II), which subsidises the purchase of electric two-wheelers, three-wheelers and buses. ACC-PLI is the matching supply-side leg: PM E-DRIVE pulls EV demand, and ACC-PLI is meant to ensure the cells that power those EVs are made in India rather than imported. Read together, the two schemes are the demand-and-supply halves of the same electrification push, and both, on the day's evidence, are running behind their headline ambitions.

For Prelims

• Full name: National Programme on Advanced Chemistry Cell (ACC) Battery Storage — the PLI scheme for battery-cell manufacturing.
• Approved: May 2021. Outlay: ₹18,100 crore. Capacity goal: 50 GWh of domestic ACC manufacturing.
• Nodal ministry: Ministry of Heavy Industries (which also runs the EV-demand schemes FAME-II / PM E-DRIVE).
• Incentive type: output-linked — paid on incremental sales of cells made in India, not an upfront capital subsidy.
• Capacity awarded: 40 GWh to four firms — ACC Energy Storage (5 GWh), Ola Cell Technologies (20 GWh), Reliance New Energy Battery Storage (5 GWh) and Reliance New Energy Battery (10 GWh).
• Capacity installed so far: ~1 GWh (with Ola Cell), against the 50 GWh goal.
• Technology basis: beneficiary firms use in-house ACC technology; the scheme is chemistry-agnostic (not locked to a single cell chemistry).
• Stated gap: domestic demand is still met largely by imports — the release itself admits the import-substitution objective is far from achieved.

What it is NOT: ACC-PLI is not a demand-side or purchase-subsidy scheme — it does not pay EV buyers; that is the job of PM E-DRIVE / FAME-II. It is not a capital subsidy paid upfront on plant and machinery; it is an incentive paid on incremental sales of cells produced in India. It is not the same as the auto and auto-component PLI, which targets vehicle and parts manufacturing, not battery cells. And "ACC" here means Advanced Chemistry Cell — not to be confused with the unrelated Appointments Committee of the Cabinet (also abbreviated ACC). It is also not run by the Ministry of New and Renewable Energy or the Ministry of Power; the nodal ministry is Heavy Industries.

The PLI set it belongs to (for "how many / match the pairs"): ACC battery storage is one of 14 PLI sectors announced from 2020, which include large-scale electronics manufacturing, IT hardware, pharmaceuticals (bulk drugs / APIs), medical devices, telecom and networking products, food processing, white goods (ACs and LED lights), specialty steel, textiles, high-efficiency solar PV modules, automobiles and auto components, advanced chemistry cell batteries, and drones. Pairing the right administering ministry to a PLI is a classic Prelims trap: ACC batteries and automobiles sit under Heavy Industries; electronics and IT hardware under MeitY; pharma and medical devices under the Department of Pharmaceuticals; solar PV modules under the Ministry of New and Renewable Energy.

Why it matters

The number that matters is the distance between 50 GWh promised, 40 GWh awarded, and 1 GWh actually installed. That gap is the whole story, and it is a textbook illustration of a recurring weakness in India's industrial-policy toolkit: the difference between a commitment on paper and capacity on the ground. PLI is an output-linked instrument, which is its strength — the Centre does not pay until the firm produces — but battery-cell manufacturing is capital-heavy, technology-intensive and globally competitive, and standing up a gigafactory takes years of plant construction, technology absorption and supply-chain qualification before a single cell ships at scale.

For a UPSC answer, the release supplies a clean, sourced, official admission. The strategic stakes are real: cells are the single most valuable component of an EV battery pack and of grid-scale storage, so a country that imports its cells has localised only the low-value assembly while the high-value chemistry, processing and cell fabrication stay offshore. India's broader energy-transition goals — a large electric-mobility push and ambitious renewable-energy and storage targets — all rest on a secure, affordable supply of cells. If domestic demand continues to be met largely by imports, the country's clean-energy build-out remains exposed to external supply chains and to the price and availability of imported cells and their critical-mineral inputs such as lithium, cobalt and nickel. That is precisely the import-dependence that the ACC-PLI was designed to reduce, and the day's figures say the design has not yet delivered.

The release is therefore useful in two opposite directions. It evidences that India is attempting genuine supply-side localisation of a strategic technology — a credible "achievement-in-progress" point. But it equally evidences the implementation lag, the gap between award and installation, that makes it a sharp problematisation point in any answer on the limits of PLI or on India's manufacturing competitiveness.
