Reliance Industries Limited (RIL) will begin production at its upcoming battery gigafactory in 2026 with an initial capacity of 40 GWh per year, the company announced during its recent annual general meeting. The facility is designed for modular expansion, with capacity expected to scale up to 100 GWh annually.

The battery plant is part of the Dhirubhai Ambani Green Energy Giga Complex in Jamnagar, Gujarat. The 44-million-square-foot site—four times the size of Tesla’s Gigafactory—also houses gigafactories for solar modules and electrolyzers, creating one of the world’s most integrated clean energy manufacturing hubs.

Anant Ambani, Executive Director of RIL, also confirmed that the company’s electrolyzer gigafactory is scheduled to begin production by the end of 2026. With the ability to scale up to 3 GW per year, the plant will leverage exclusive technology partnerships and in-house expertise to enable cost-competitive production of green hydrogen at scale.

Meanwhile, RIL’s solar PV manufacturing facility at the complex has already produced its first 200 MW of heterojunction technology (HJT) solar modules. These high-efficiency modules deliver 10% higher energy yield, 20% better temperature tolerance, and 25% lower degradation compared to conventional products. The solar plant will be scaled to 10 GW annually in the near term, with further expansion to 20 GW, positioning it as the world’s largest single-site solar manufacturing complex.

Together, these platforms—solar, battery storage, and green hydrogen—will form a gigawatt-scale clean energy ecosystem within a single location. Ambani emphasized that the integrated approach offers competitive advantages in scale, technology, cost, and supply chain resilience, adding: “Reliance will be the world’s only fully integrated, self-sufficient new energy company.”

Construction of the Jamnagar Giga Complex is progressing rapidly, with RIL aiming to establish an unmatched global benchmark in clean energy manufacturing.
