Production Linked Incentive (PLI) Scheme for National Programme on Advanced Chemistry Cell (ACC) Battery Storage helps firms set up giga-scale battery cell manufacturing units in India. Selected companies get cash incentives to boost domestic output and cut import dependence.
Ministry of Heavy Industries runs this scheme with a total outlay of ₹18,100 crore over 5 years. The target is 50 GWh of ACC capacity, plus 5 GWh for niche technologies. A fresh global tender for the remaining 10 GWh is open now for grid-scale stationary storage.
Production Linked Incentive (PLI) Scheme for National Programme on Advanced Chemistry Cell (ACC) Battery Storage - Introduction
Ministry of Heavy Industries (MHI) runs the Production Linked Incentive (PLI) Scheme for the National Programme on Advanced Chemistry Cell (ACC) Battery Storage. Government of India invites domestic and global investors to build giga-scale ACC manufacturing units with strong value addition within a set time. The scheme supports 50 GWh of battery storage capacity, plus 5 GWh for niche technologies. Selected firms must commission their plants within 2 years, and incentives are paid over the next 5 years based on performance.
The scheme was approved by the Union Cabinet on 12 May 2021 with an outlay of ₹18,100 crore. It is technology neutral, so better performing technologies get higher incentives. Money spent on research and development (R&D) also counts toward the investment requirement, which helps firms use newer technology.
Latest Update 2026
Ministry of Heavy Industries has invited global bids for 10 GWh of ACC battery manufacturing capacity. This remaining capacity is set aside for grid-scale stationary storage (GSSS) applications. Out of the total 50 GWh target, 40 GWh has already been awarded to four firms.
Tender documents are available from 15 July 2026. The pre-bid conference was held on 29 July 2026, and the last date to submit bids is 13 October 2026. Technical bids will open on 14 October 2026. Earlier, under Round-2 bidding, M/s Reliance New Energy Battery Ltd signed a Programme Agreement on 17 February 2025 for a 10 GWh facility. For Round-2, the scheme period is 7 years from the appointed date of 1 July 2025, with the first 2 years as the gestation period.
