Rapid electrification of India's road transport fleets across all vehicle categories could lower the country's combined annual crude oil and battery import expenditure by up to $125 billion by 2050, according to a working paper released by the International Council on Clean Transportation (ICCT) at the India Clean Transportation Summit 2026.
The study indicates that $94 billion of the potential savings is generated directly by the rate of EV adoption alone, even if all battery cells are sourced through imports. The remaining $31 billion in savings depends on expanding domestic cell manufacturing to achieve self-sufficiency. The finding reflects that the financial savings from avoided petrol and diesel imports substantially exceed the procurement costs of imported battery cells.
The study said that under a baseline oil price assumption, the difference between the slowest and fastest electrification adoption paths accounts for a $104 billion difference in annual import costs by 2050. In a high crude oil price scenario, that divergence widens to $166 billion annually.
Amit Bhatt, India Managing Director at ICCT, noted, "The faster India electrifies, the less exposed it is to global crude price shocks, and the stronger its case for Aatmanirbhar Bharat. Localizing battery manufacturing adds real value on top, but the pace of the transition is what protects India first."
The working paper models battery demand across two-wheelers, three-wheelers, passenger cars, light commercial vehicles, buses, and heavy trucks between 2024 and 2050. Across all scenarios, domestic battery requirement rises sharply after 2030, climbing to 340 gigawatt-hours (GWh) under baseline projections and 573 GWh under aggressive adoption cases by 2050. Because domestic cell production requires time to establish scale, the study notes that imports will supply almost all of India's battery cells through 2030.
Addressing the summit, Sushant Naik, Chairman of the SIAM Electric Mobility Group and Chief Corporate Affairs Officer at Tata Motors, said, "The auto industry has already brought imports down by around 20,000 crore by manufacturing for the India market, and the technology pathway we build from here should progressively take away strategic dependency, which means building not only batteries and motors on Indian soil but the skills and design capability behind them. That is why localization is now being assessed across the value chain rather than only at final assembly, and why the shift is from localizing a product to a process."
Study co-author Namita Singh stated, "Every electric vehicle India puts on the road reduces its dependence on imported oil, whether the batteries are manufactured domestically or imported. Accelerated EV adoption alone could cut India's road transport import bill by 61% by 2050. Coupling rapid manufacturing with domestic battery manufacturing could raise those savings to 82%, equivalent to about $125 billion annually."
