Premier Energies is expanding into the battery energy storage system (BESS) segment through a proposed joint venture with RCT India, a subsidiary of Germany-based RCT Group, to establish a 12 GWh BESS manufacturing facility in Telangana.
The company’s subsidiary, Premier Battery Technologies Private Limited, will execute the project in partnership with RCT India. The proposed facility will be developed in phases, with the first phase expected to have a manufacturing capacity of 6 GWh.
The partnership marks a strategic expansion of Premier Energies beyond its established solar cell and module manufacturing business, as demand for energy storage systems increases alongside the rapid deployment of renewable energy projects in India.
The binding term sheet sets the framework for the proposed joint venture, which is expected to focus on manufacturing BESS solutions for the growing utility-scale and industrial energy storage market. The companies also intend to develop globally competitive storage solutions, with the potential to support exports from India.
The proposed BESS facility will add a new dimension to Premier Energies’ clean-energy portfolio. The company currently has significant solar manufacturing capabilities, with its total solar module manufacturing capacity reaching 11.1 GW following recent capacity additions. It is also developing additional solar cell manufacturing capacity.
The planned storage manufacturing project comes at a time when India is seeking to rapidly expand energy storage capacity to support the integration of intermittent renewable power into the electricity grid. Battery storage is expected to play an increasingly important role in balancing supply and demand, improving grid flexibility and enabling greater utilisation of solar and wind power.
Premier Energies has also been strengthening its manufacturing footprint in Telangana. In July 2026, the company inaugurated a 5.6 GW solar module manufacturing plant at Seetharampur, taking its overall module manufacturing capacity to 11.1 GW. The company also conducted a groundbreaking ceremony for a 6 GWh BESS container plant as part of its broader expansion plans.
The BESS venture comes as Premier Energies continues to report strong business growth. For the first quarter of FY27, the company reported consolidated net profit of ₹472 crore, representing a 53.3 per cent year-on-year increase. Consolidated revenue rose 34.1 per cent year-on-year to ₹2,508 crore.
As of June 30, 2026, Premier Energies’ total order book stood at approximately ₹15,000 crore, providing substantial revenue visibility as the company expands its manufacturing operations across clean-energy segments.
The proposed 12 GWh BESS project is expected to complement Premier Energies’ existing solar manufacturing operations and strengthen its position across the renewable energy value chain. By adding battery storage to its portfolio, the company aims to participate in a market expected to grow alongside India’s renewable energy and grid-modernisation requirements.
However, the transition into BESS manufacturing also brings new operational and technology considerations. Battery technologies are evolving rapidly, while supply chains for cells, critical minerals and other components remain exposed to global market conditions. The ability to scale manufacturing efficiently and maintain technological flexibility will therefore be important to the project’s long-term competitiveness.
The next key steps for the proposed joint venture are expected to include execution of definitive agreements, financial closure and further details on the timeline and implementation of the initial 6 GWh manufacturing phase.
With the planned 12 GWh facility, Premier Energies is positioning itself to participate in India’s emerging domestic battery storage manufacturing ecosystem while building on its existing presence in solar manufacturing.
