Octillion opens third Indian battery plant in Gujarat, adding 3 GWh of capacity per year

Octillion Power Systems has opened its third battery manufacturing plant in India, in Halol, Gujarat. The Tier 1 supplier converted an empty structure into a fully operational plant in less than eight months.

The plant covers more than 13,000 square meters and will build over 48,000 battery systems a year at full capacity, or more than 3 GWh of energy storage. Across all three of its Indian sites, Octillion expects annual output to top 150,000 battery systems and roughly 9 GWh, going into passenger vehicles, buses and commercial trucks.

The Halol plant builds Octillion’s standardized production process, thermal modeling and battery management systems into the local supply base, an approach the company says goes beyond assembly and shortens lead times.

Research from the International Institute for Sustainable Development puts net localization of high-value components such as cells, motors and controllers below 20% for many manufacturers, and finds India heavily dependent on imported lithium, cobalt and nickel for battery production. The government’s National Critical Minerals Mission is funding domestic exploration and processing capacity.

EV sales in India reached more than 1.54 million units in the first half of 2026, up 43% year on year, and EV penetration passed 11%, according to JMK Research. Electric passenger cars rose 83% over the same period and electric buses 42%, on the strength of deployments under the government’s PM E-Bus Sewa and PM E-DRIVE programs, including more than 4,200 e-buses allocated in June 2026. Electric trucks are still an early-stage segment, but cumulative sales are up more than 300% year on year.

“A resilient EV supply chain in India can’t just mean more square footage—it means depth: local sourcing, local quality control, and local engineering talent working side by side with our global standards,” said Nikhil Parchure, Senior Vice President at Octillion. “That’s what we’ve built in Halol.”
