India’s ACC Battery Demand Set to Surge to 700 GWh by Mid-2040s: IESA Report

India’s demand for Advanced Chemistry Cell (ACC) batteries is projected to surge from 28 GWh in 2025 to over 700 GWh by the mid-2040s, driven by electric mobility and large-scale energy storage, according to the India Energy Storage Alliance (IESA).

The report, 'Vision 2047: India’s Roadmap for a Self-Reliant Battery Ecosystem,' was unveiled at the India Battery Manufacturing and Supply Chain Summit (IBMSCS) 2026. It highlights Lithium Iron Phosphate (LFP) batteries and their variants as expected to comprise over 60 percent of total demand by 2047, thanks to cost efficiency, thermal stability, and safety.

Rajesh Kulhari, Joint Secretary, Ministry of Renewable Energy, emphasised that India’s energy storage revolution requires close collaboration among policymakers, regulators, utilities, financiers, manufacturers, developers, and researchers.

Debmalya Sen, President of IESA, called the growing battery demand both “an enormous opportunity and a strategic imperative” for building robust domestic manufacturing capabilities.
