Renewable Energy
The new joint venture aims to transform Telangana into a manufacturing hub for BESS systems for commercial, industrial, and large-scale projects, serving customers both within and outside India.
Premier Energies and RCT India plan a 12 GWh BESS factory in the state of Telangana, India, marking a shift for the Indian manufacturer beyond its traditional solar cell and module business. According to information published by pv magazine India on September 11, 2026, the first phase will feature 6 GWh and is expected to be operational by June 2027, while the total projected capacity will reach 12 GWh.
The project will be developed through Premier Battery Technologies, a subsidiary of Premier Energies, in partnership with RCT India, part of the German group RCT Solutions. The companies have already signed a binding term sheet to establish the joint venture.

Therefore, the factory is not yet operational, and the 12 GWh capacity does not represent current production levels; it reflects the planned scale for the facility.
The scale of the new unit highlights the shift intended by Premier Energies.
Instead of focusing solely on solar manufacturing, the company aims to directly enter another part of the renewable energy chain: storage.
The projected facility will have a total capacity of 12 GWh of battery energy storage systems, known as BESS. However, the companies will divide the deployment into phases.
The first phase will have 6 GWh, exactly half of the announced final capacity, and is expected to begin operations by June 2027.
Subsequent expansion is expected to bring the facility to the planned 12 GWh.
This leap into a new industrial front occurs as manufacturers across various sectors are rapidly expanding their capabilities in India. Mass production is gaining traction in the country as companies bet on the growth of markets linked to electrification.
In the case of Premier Energies, however, the emphasis is directly related to one of the biggest challenges in solar and wind expansion: storing electricity for use when renewable generation decreases or when grid demand increases.
The strategic shift may be the most significant aspect of the initiative.
Premier Energies built its industrial presence primarily in the manufacturing of solar cells and modules. Now, the joint venture will add storage systems to its repertoire.
This means expanding the company’s role within the clean energy chain.
Initially, the company manufactures equipment that generates electricity from the sun. With the new operation, it also aims to participate in the segment responsible for storing part of that energy.
Premier Energies itself described the partnership as a strategic step in its evolution to become a clean energy company with a presence in various segments of the renewable chain.
The company’s managing director, Chiranjeev Saluja, stated that storage has become a necessity for the Indian electrical system as the country expands its renewable capacity.
According to him, battery systems will play an important role in building a more reliable, resilient, and sustainable grid.
Premier Energies contributes industrial capacity, while RCT aims to provide technical knowledge, engineering, and international experience.
According to the information disclosed, RCT Solutions Group has accumulated over 10 GW of experience in BESS-related projects worldwide.
The group also has internal engineering and operations teams focused on gigawatt-scale battery storage projects in Europe.
Thus, the division of roles creates a clear combination.
Premier Energies brings its manufacturing setup from India, while RCT adds engineering expertise, international supply chain capabilities, and storage project development.
This strategy resembles moves observed in other industrial chains, where companies aim to transform technological knowledge into physical production capacity. A factory that received R$ 300 million to expand its lines, for instance, illustrates how installed capacity and industrial scale can become decisive when a company seeks to serve larger markets.
In the battery sector, this challenge takes on another dimension because expansion must simultaneously keep pace with renewable generation, electrical grids, and storage demand.
An electrical grid cannot solely rely on how much a plant can produce at its peak time.
The problem becomes evident a few hours later.
Solar panels stop generating electricity at night, while wind turbines depend on wind availability. Meanwhile, homes, industries, and businesses continue to consume energy.
It is during this gap that BESS systems can assume a strategic role.
Batteries store electricity during periods of higher availability and can deliver it back to the grid later. Additionally, such systems can contribute to grid flexibility and the integration of larger volumes of variable generation.
Thus, the rapid advancement of renewable sources in India is also increasing the demand for large-scale storage.
The joint venture aims to target this very market.
The companies have not limited future production to a single type of consumer.
According to pv magazine India, the unit is projected to cater to commercial, industrial, and utility-scale applications.
The latter segment includes large-scale storage projects associated with the electrical system.
Thus, a facility of 12 GWh can produce solutions for various points along the chain.
Companies can use batteries to manage consumption and demand. Renewable energy developers can combine storage with solar or wind plants. Meanwhile, grid-scale projects can employ large systems to balance generation and consumption.
Consequently, Premier Energies is not just entering a new product.
It is entering a market that is growing precisely as a result of the expansion of the sector in which it already operates.
There is also a second part of the strategy.
Production will not be directed exclusively to India.
Premier Energies and RCT state that the factory will also cater to international markets, turning the facility into an export-oriented manufacturing platform.
This increases the significance of RCT’s international experience.
The group aims to leverage its global supply network and sector knowledge to develop competitive BESS products in various markets.
At the same time, manufacturing in India could place the joint venture within an industrial chain attempting to gain global scale across different technologies.
Such a combination of engineering, manufacturing, and international markets also appears in the technology industry. A startup valued at US$ 2 billion, for example, is preparing a new generation of hardware while seeking to transform technological development into commercially available infrastructure.
For Premier Energies and RCT, the equation will be similar in one fundamental point: designing the technology is just one step; it will be necessary to produce it at scale and secure enough customers to occupy the installed capacity.
The announced scale warrants an important caveat.
The BESS factory of 12 GWh is still a project.
The companies have signed a binding agreement to form the joint venture and announced the intended capacity. Therefore, it would not be correct to present the 12 GWh as already available production.
The first operational milestone disclosed is June 2027, when the initial phase of 6 GWh is expected to begin operations.
Additionally, the source does not specify how much money Premier Energies and RCT intend to invest in the facility.
It also does not detail, in this announcement, the timeline for expanding from the initial 6 GWh to the full 12 GWh.
Therefore, assigning a value of investment or a definitive date for the full capacity would mean going beyond the disclosed data.
The project also reveals a commercial ambition greater than simply fueling renewable growth in India.
Saluja stated that the long-term partnership with RCT provides access to the storage market and that the goal is to manufacture globally competitive BESS products in India.
Meanwhile, Sukumar Reddy Madugula, managing director of RCT India, highlighted the international experience, engineering, and execution capability that the group intends to bring to the operation.
Thus, the two companies are trying to build a platform that combines Indian production with international knowledge.
If the deployment progresses as planned, the factory will start with 6 GWh in 2027 and will have the capacity to reach 12 GWh.
This scale will place Premier Energies in the midst of a significant transformation.
The company that established its presence by manufacturing equipment to generate solar energy will also start producing systems designed to store electricity.
There is a technological irony in this transformation.
The more solar panels and wind turbines enter the electrical grid, the greater the need for flexibility in managing the times when these sources are not producing.
For this reason, storage and renewable generation tend to advance together.
Premier Energies now aims to participate in both sides of this equation.
On one side are the solar cells and modules that are already part of its business. On the other will be the BESS systems of the new joint venture.
The RCT Solutions Group, for its part, brings to the partnership over 10 GW of experience in storage-related projects.
The first concrete test will be to put the initial 6 GWh into operation by June 2027. After that, the companies will still need to advance to the projected total capacity of 12 GWh and transform industrial scale into actual sales in India and abroad.
If they succeed, the Telangana facility could represent more than just a new factory: it will signify Premier Energies’ transition from a solar-focused manufacturer to a company also present in one of the technologies required to support the growth of that very renewable generation.
Do you believe that 12 GWh battery factories can make India a direct competitor to the major Asian energy storage hubs, or will the global supply chain remain concentrated among the current industry leaders?
