Cygni Energy and Indus Towers will explore BESS manufacturing capacity of up to 1.5 GWh for telecom applications
The companies will evaluate higher-capacity and emerging battery technologies for telecom infrastructure
Cygni currently operates a 4.8 GWh cell-to-container BESS facility in Hyderabad and plans to expand its overall capacity beyond 10 GWh
Indian energy storage manufacturer Cygni Energy and telecom infrastructure company Indus Towers have joined hands to explore up to 1.5 GWh of battery energy storage system (BESS) manufacturing in India to serve telecom infrastructure.
The duo has signed a memorandum of understanding (MoU) and plans to establish manufacturing capacity to meet the ‘evolving energy requirements’ of telecom infrastructure in India. The partnership will also evaluate advanced battery technologies for telecom applications.
Formed by the merger of Bharti Infratel Limited and Indus Towers, Indus Towers Limited had over 267,611 towers and 432,250 co-locations as of June 30, 2026. It is present across 22 telecom circles.
While Cygni's official statement does not reveal details about the MoU, telecom companies have been exploring energy storage as a backup power strategy to improve operational efficiency. According to Battery Council International (BCI), batteries can help provide stable power for data centers and telecom systems.
Incubated at IIT Madras, Cygni Energy develops energy storage products for telecom, stationary energy storage, mobility, and other applications. Its battery portfolio currently includes 100 Ah solutions and could expand to higher-capacity systems, including 314 Ah.
“We plan to develop capacity of up to 2 GWh, while building a portfolio that can evolve from today’s 100Ah solutions to higher-capacity 314Ah systems and emerging battery technologies,” said Cygni Energy Founder & CEO Venkat Rajaraman.
In 2025, Cygni Energy opened a 4.8 GWh cell-to-container BESS Gigafactory in Hyderabad’s Maheshwaram, with plans to scale it up to exceed 10 GWh in the future.
“Our ambition is to combine scale, reliability and Indian engineering to create future-ready energy storage solutions that can evolve alongside India’s rapidly expanding digital infrastructure,” added Rajaraman.
According to Crisil, India could see up to 50 GWh of BESS installations by FY2028 as the technology helps improve power availability during peak demand. However, reducing reliance on overseas suppliers remains important to limit exposure to global supply disruptions and procurement uncertainties (see Crisil Projects India To Add 50 GWh BESS Capacity By FY2028).
