- Octillion’s solar-powered battery facility drives clean-energy manufacturing in India, reinforcing the company’s commitment to solar-powered battery facilities as it moves towards complete carbon neutrality.
- The solar-powered battery facility strengthens India’s EV supply chain by delivering three gigawatt-hours (GWh) of battery capacity each year through dedicated clean energy.
Octillion, the California-based electric vehicle (EV) battery manufacturer, has completed its transition to solar energy at one of its major production sites in India. The Pune factory opened in June 2023. It began its solar conversion in June 2024 and reached full solar operation by July 2025. Moreover, the shift took only 13 months. The company announced the achievement in a recent statement, highlighting its commitment to long-term sustainability.
The facility covers 8,200 square metres, roughly the size of two football pitches. It produces 3 GWh of battery capacity every year for India’s fast-growing EV market. Additionally, the rooftop solar system now generates about 545 MWh of clean electricity annually. This output meets the plant’s entire energy demand. Consequently, Octillion now manufactures all EV battery systems using renewable power.
The Pune site is the first of Octillion’s Indian factories to operate entirely on solar energy. It also supports the firm’s goal of achieving carbon-neutral operations across all India-based sites by 2027. Octillion plans to apply this model to its remaining factories. Therefore, each stage of the EV battery life cycle will follow a cleaner and more sustainable energy pathway.
Octillion’s switch to solar reflects a broader trend of captive solar projects across Pune and Maharashtra. For example, Tata Motors expanded its on-site solar generation by adding a 12 MWp plant. This addition raised the total capacity to about 20.7 MWp at the Pune commercial vehicle unit. Meanwhile, ŠKODA-VW installed an 8.5 MWp rooftop system at its Chakan plant. The installation now meets around 15% of the plant’s annual energy needs. Additionally, smaller manufacturers, such as SKF, have adopted rooftop systems to reduce costs and carbon emissions. Maharashtra has also exceeded 1 GW of domestic rooftop installations. Altogether, these developments indicate a clear shift towards cleaner industrial energy, supported by stronger supply chains and improved
Paul Beach, Global President of Octillion, stated that India’s EV market is expanding rapidly and that the company wants this growth to remain sustainable. He also said that producing battery systems with clean power brings Octillion closer to its 2027 carbon-neutral goal. Nikhil Parchure, Senior Vice President, added that Octillion operates three major manufacturing plants, two in Pune and one in Gujarat. He explained that this network enables the company to meet India’s growing demand for batteries. Furthermore, he emphasised that Octillion has built a reliable national supply chain over the past decade, offering consistent support in cost, volume, and delivery.
