Replus Engitech and Indus Towers have signed a memorandum of understanding to explore battery energy storage systems for telecom infrastructure in India, with Replus planning to make available dedicated production capacity of 1.5 gigawatt-hours over two years.
HEG Advanced Materials, which backs Replus Engitech, disclosed the arrangement in an exchange filing on Wednesday. The proposed collaboration is intended to address the evolving energy requirements of telecom infrastructure, while supporting greater reliability and energy efficiency across telecom applications.
Indus Towers is one of India’s leading telecom infrastructure companies and operates across all 22 telecom circles. Its customers include Bharti Airtel, Reliance Jio Infocomm and Vodafone Idea Limited. The company’s nationwide footprint gives the proposed storage partnership relevance across a broad network of telecom sites, although the MoU does not specify the number of locations or the deployment schedule.
Under the arrangement, Replus also plans to expand its telecom energy storage portfolio, including higher-capacity battery systems. The companies will explore technologies such as sodium-ion batteries, which Replus said could support reliability, energy efficiency and lifecycle performance in telecom applications. The filing did not disclose the commercial value of the MoU or identify specific products to be deployed by Indus Towers.
Replus Engitech is an integrated energy storage and clean energy company involved in advanced battery technologies, battery energy storage systems, telecom energy solutions and e-mobility. It designs, manufactures and deploys advanced chemistry cell-based lithium-ion battery systems, and provides system integration, engineering, procurement and construction, operations and maintenance, and lifecycle energy asset management services.
The company said it has deployed more than 1 GWh of energy storage capacity across battery energy storage systems, electric mobility, telecom power solutions and hybrid energy applications. The proposed 1.5 GWh capacity allocation for telecom infrastructure would therefore represent a dedicated manufacturing commitment over the stated two-year period, rather than a confirmed deployment figure.
Riju Jhunjhunwala, chairman, managing director and chief executive officer of HEG Advanced Materials, said the initiative would help build a domestic energy storage ecosystem for critical infrastructure while developing manufacturing scale and technology capabilities. Hiren Pravin Shah, managing director and chief executive officer of Replus Engitech, said the company aimed to combine innovation, reliability and Indian engineering for the changing needs of telecom infrastructure.
The announcement places telecom power requirements within the wider expansion of India’s energy-storage manufacturing and deployment ecosystem. For telecom infrastructure providers, storage systems can form part of the power architecture supporting network equipment, but the companies have not yet announced project-level specifications, investment details, procurement milestones or commissioning dates. Further implementation details will depend on the outcome of the collaboration and the technologies selected.
