India battery energy storage system expansion
Overview
India is expanding its battery energy storage system (BESS) infrastructure through regulatory adjustments, large-scale tenders, and strategic industrial partnerships.
In September 2026, the Central Transmission Utility of India Limited (CTUIL) issued an advisory allowing existing BESS projects to increase their energy storage capacity (MWh) without changing their approved charging or discharging capacity (MW). Concurrently, major entities such as Coal India Limited and Cochin Shipyard Limited initiated tenders for BESS capacity to support renewable energy goals and grid connectivity.
By October 2026, the focus expanded to specialized infrastructure, as Indus Towers Ltd and Cygni Energy Pvt Ltd signed a Memorandum of Understanding to develop energy storage solutions for the telecom sector. This partnership aims to establish a BESS manufacturing capacity of up to 1.5 GWh, utilizing advanced battery technologies to improve the reliability and sustainability of India’s digital infrastructure.
