Octillion Turns Pune EV Battery Plant Fully Solar-Powered, Generating 545 MWh of Clean Power Annually

Octillion has switched its 8,200 square metre Pune EV battery manufacturing plant entirely to rooftop solar, generating about 545 MWh of clean power annually and meeting 100 percent of its energy needs. The company aims to make its all three India-based facilities carbon neutral via solar power generation by 2027.

California-based Electric Vehicle (EV) battery manufacturer Octillion has announced the successful completion of a facility-wide conversion to solar energy at one of its three battery system manufacturing factories in India.

Inaugurated in June 2023, the Pune facility began its solar conversion in June 2024 and achieved full operational status by July 2025—just 13 months later, the company said in a statement.

Spanning approximately 8,200 square meters, the factory produces about 3 GWh of total annual battery capacity for India's fast-growing electric vehicle market. Its new rooftop solar installation will provide approximately 545 MWh of dedicated clean energy annually, fully covering the facility's entire power requirements, the company stated.

This facility marks the first of Octillion's factories to achieve full conversion to 100 percent solar energy. This milestone anchors a larger, comprehensive sustainability initiative aimed at making all of the company's India-based facilities carbon neutral via solar power generation by 2027, it said.

Paul Beach, Global President of Octillion, commented, “India's electric vehicle market is accelerating rapidly, and we're committed to ensuring this growth is truly sustainable. By converting our manufacturing to solar power, we're closing the loop – producing the clean energy storage solutions of tomorrow, using clean energy today. This is just the beginning of our journey toward our goal of carbon-neutral operations across all our India facilities by 2027.”

Nikhil Parchure, Senior Vice President at Octillion, added, “Accelerating cleaner, more efficient transportation in India is central to our mission as a global battery company. With three large-scale battery manufacturing facilities in India, two in Pune and one in Gujarat, Octillion is uniquely positioned to serve the fast-growing needs of India's electric vehicle sector; in volume, cost, and convenience. Over the last decade, we have created a robust national supply chain that India's automotive sector can rely on.”

He further added, “We will continue to advance our efforts in India and globally by providing cutting-edge, safe battery systems, working to leave the least environmental impact possible in the transportation sector.”
