Built with an investment of about INR 100 crore, with an initial capacity of 4.8 GWh, the factory will manufacture battery packs for electric vehicles and grid-scale energy storage.
Cygni has manufactured and delivered 500 MWh of batteries for the power and energy sector and currently has a robust order pipeline of 1 GWh for BESS projects and EV battery packs, said the company in a statement.
The production line is equipped to manufacture 105 kWh liquid-cooled base modules using advanced 314Ah cells, forming the core components of most energy storage containers globally.
Venkat Rajaraman, Founder and CEO of Cygni said, “This Gigafactory positions us to lead in the energy storage sector, delivering high-quality, safe battery packs across multiple applications. Cygni's Automated BESS Assembly Line is engineered for advanced, high-quality BESS module manufacturing, leveraging globally recognized best practices such as Poka-Yoke-enabled stations and end-to-end traceability. We plan to grow exponentially in energy storage over the next few years in India and internationally.”
He further added that in Phase II, the company will be expanding the Gigafactory’s capacity to 10.8 GWh within the existing facility. “With a total investment of INR 250 crore across 2 phases, this will result in direct and indirect job creation of over 1,000 jobs in the next 24 months. As part of this expansion, we will be adding three additional automated 2 GWh cell-to-pack manufacturing lines and container integration facilities to our existing lines, to meet the rising demand for stationary and e-mobility storage applications,” he added.
Looking ahead, Cygni will offer advanced, high-capacity energy storage solutions with modular and scalable architectures, integrated with cutting-edge technologies such as Machine Learning for predictive analytics, Digital Twin systems for real-time monitoring, and high-performance energy management platforms.
These systems will feature seamless integration with smart grid codes and precision-engineered manufacturing. Through its long-term collaboration with IIT-Madras, Cygni is also advancing research into next-generation technologies and chemistries, including Cell-to-Pack (CTP) and Cell-to-Chassis (CTC) design architectures, sodium-ion batteries, and supercapacitors.
