Replus Engitech, a subsidiary of Noida-based HEG Advanced Materials, has secured a domestic order worth ₹127.35 crore from Indus Towers for the supply of lithium-ion battery banks. The company disclosed the order in a regulatory filing dated October 1, 2026. The contract further expands the business relationship between the two companies as they explore opportunities in battery energy storage solutions for India’s telecom infrastructure.
According to the regulatory filing, the purchase orders have been awarded by a domestic entity and cover the supply of lithium-ion battery banks. The execution of the orders is scheduled for completion by May 31, 2027, or another date mutually agreed upon by the parties. However, the filing does not specify the total number of battery banks to be delivered or provide individual purchase order details.
The latest order comes a day after HEG Advanced Materials announced that its subsidiary, Replus Engitech, had signed a Memorandum of Understanding (MoU) with Indus Towers to explore collaboration in Battery Energy Storage System (BESS) solutions for telecom infrastructure across India.
Under the proposed collaboration, Replus intends to make available approximately 1.5 GWh of dedicated BESS manufacturing capacity over the next two years to address the energy storage requirements of telecom infrastructure. The proposed arrangement is aimed at supporting the development and deployment of battery-based energy storage solutions for the telecom sector.
The collaboration also includes plans to expand Replus Engitech’s telecom energy storage product portfolio, particularly through the development of higher-capacity battery systems. In addition to its existing lithium-ion battery offerings, the company is exploring emerging technologies, including sodium-ion batteries, for potential applications in telecom infrastructure.
The latest ₹127.35 crore contract follows another significant order placed by Indus Towers with Replus Engitech earlier in September 2026. Under the previous agreement, the subsidiary secured a purchase order worth ₹217.56 crore for the supply of lithium-ion battery banks.
The earlier contract is scheduled for execution by March 31, 2027, with the possibility of extending the timeline through mutual agreement between the two companies.
With the two orders, Replus Engitech has received lithium-ion battery bank contracts worth a combined ₹344.91 crore from Indus Towers. Both orders are associated with the supply of battery systems for the domestic market.
The successive orders and proposed BESS collaboration highlight the expanding engagement between Replus Engitech and Indus Towers in the telecom energy storage segment. Battery systems play an important role in maintaining uninterrupted power availability at telecom sites, particularly where grid supply is inconsistent or backup power is required.
Through its proposed 1.5 GWh dedicated BESS capacity allocation, Replus aims to address the growing energy storage requirements of telecom infrastructure while broadening its portfolio across lithium-ion and emerging battery technologies.
The latest contract adds to the company’s existing order commitments from Indus Towers, while the proposed collaboration provides a framework for exploring larger-scale battery storage deployments and technology development for telecom applications in India.
