Telecom Industry Shifts to Battery Storage and Renewables in India
Telecom towers in India are transitioning from diesel reliance to battery energy storage and hybrid renewable systems. This shift, driven by rising energy demands and cost efficiency, aims to enhance operational reliability and support India's net zero emissions goal by 2070.

India's telecom sector operates approximately 824,000 towers, with around 35-40% still relying on diesel generators. The number of diesel-free towers increased from 90,000 in 2016 to over 223,000 by March 2024, saving around 550 million liters of diesel annually.
Battery energy storage systems (BESSs) and hybrid solutions are gaining traction as utility-scale solar power costs drop significantly compared to diesel. Key technologies include lithium-ion batteries, which offer longer life and efficiency, and emerging options like sodium-ion and flow batteries.
The telecom industry is investing in 1,250 MW of planned solar capacity, aligning with India's renewable energy expansion. Rising diesel costs and energy security concerns are accelerating the shift away from fossil fuels, with a significant reduction in diesel dependence expected by 2030. This move could lead to more resilient telecom infrastructure capable of enduring power disruptions.
