Premier Energies BESS expansion: 6 GWh plant, JV in 2026

What Premier Energies has announced

Premier Energies Limited has outlined multiple moves to broaden its renewable energy platform beyond solar manufacturing. The company has commenced construction of a 6 GWh Battery Energy Storage System (BESS) facility and an aluminium frames unit with annual capacity of 18,000 metric tonnes at its 75-acre Seetharampur manufacturing campus. In parallel, its board has approved the incorporation of a wholly owned subsidiary to expand into battery energy storage systems, battery cells and battery materials.

The company has also formed a strategic joint venture with BA Prerna Renewables Private Limited through HeliosAnthos Energies Private Limited. Under the arrangement, Premier Energies holds 51% and BA Prerna holds 49%, and the venture is positioned to pursue EPC opportunities across solar, wind and hybrid projects in India.

Groundbreaking at Seetharampur: 6 GWh BESS and aluminium frames

The company has stated that construction has begun on a 6 GWh BESS facility as well as an aluminium frames plant with 18,000 metric tonnes per annum capacity at the same campus. The projects are part of an expansion of the Telangana complex as Premier Energies moves beyond solar cell and module manufacturing into adjacent parts of the clean-energy supply chain.

Premier Energies has also linked the Seetharampur site to local employment generation. Once fully operational, the 75-acre facility is expected to create more than 3,000 jobs for local communities, as per the information provided.

A 12 GWh BESS plan in two phases

Beyond the initial 6 GWh project, Premier Energies is developing a larger 12 GWh BESS facility structured in two phases of 6 GWh each. The company has indicated that construction is already underway and that a technology partner for containerized solutions is expected to be finalised in the next two to three months.

Management has also said it is deliberately pacing expansion while awaiting government guidelines on non-tariff barriers for BESS manufacturing. That sequencing matters because BESS manufacturing economics can be sensitive to policy frameworks, localisation requirements and import-related rules.

Wholly owned subsidiary for battery storage, cells and materials

Premier Energies Ltd has approved the incorporation of a wholly owned subsidiary to expand into battery energy storage systems, battery cells, battery materials, and related electronics, hardware and software businesses. The authorised capital for the subsidiary is ₹0.10 crore, divided into 1,00,000 equity shares of ₹10 each.

The company will subscribe to 50,000 shares aggregating ₹0.05 crore. This structure signals an initial corporate setup step rather than a fully funded capex announcement, but it establishes a dedicated vehicle for battery-related lines that are now being added alongside solar manufacturing.

Strategic JV with BA Prerna to build EPC capability

Premier Energies has formed a strategic joint venture with BA Prerna Renewables Private Limited through HeliosAnthos Energies Private Limited. Premier Energies will hold 51% and BA Prerna will hold 49%. The joint venture will focus on EPC contracts for solar, wind and hybrid projects across India.

The scope described includes end-to-end execution, from land acquisition to commissioning. For Premier Energies, the JV aligns with its stated strategy to strengthen downstream capabilities and expand its presence across a broader renewable energy value chain, complementing its manufacturing base.

Proposed K-Solare acquisition JV called off

Separately, Syrma SGS Technology Limited and Premier Energies Limited have decided not to proceed with their proposed joint venture to acquire K-Solare Energy Private Limited. The stated reason is that conditions precedent were not fulfilled.

This development provides useful context because it shows Premier Energies is recalibrating partnership routes. While one proposed JV has been discontinued, the company has proceeded with another JV focused on EPC and has moved ahead with battery-related capacity and corporate structuring.

Manufacturing roadmap: modules, cells, BESS, and more

Premier Energies has expanded solar module capacity to 11.1 GW and has 7 GW of TOPCon cell capacity under construction. Alongside, the company is developing BESS manufacturing, including a 12 GWh facility and containerised solutions that are linked to the technology partner selection timeline.

The broader manufacturing strategy also includes adding a 10 GW ingot-wafer complex with target completion in December 2027, a 12 GWh BESS facility with target completion in June 2027, and a 3 GW inverter production facility. The company has also highlighted expansion of its transformer business, with a target to grow transformer capacity to 280 GVA by 2030.

Financial snapshot and order book

The company reported revenue growth of 20.7% year-on-year to ₹80,259 crore, while PAT grew 61.1% year-on-year to ₹15,097 crore. EBITDA margin improved to 32.13%. The order book reached ₹14,010 crore, representing 9,383 MW.

Management has also guided that revenue could “treble” from an approximately ₹400 crore base over the next three years, with EBITDA margins expected slightly above the 15% industry-cycle average mentioned. In addition, the company has stated an ambition to expand BESS revenue share to 15% to 20% by 2030.

Key facts at a glance

Why this matters for Premier Energies’ positioning

Taken together, the announcements show Premier Energies building a portfolio that spans manufacturing, storage, and project execution. The BESS build-out and subsidiary incorporation both point to a clearer organisational and industrial push into storage, while the BA Prerna JV is positioned to extend reach into EPC for solar, wind and hybrid assets.

At the same time, the company’s stated approach of pacing BESS expansion while awaiting non-tariff barrier guidelines highlights that policy clarity remains part of the execution path for domestic battery storage manufacturing.

What to watch next

Near-term attention is likely to remain on the finalisation of the BESS technology partner for containerised solutions in the next two to three months, and on updates around the phased 12 GWh plan. Investors and industry participants may also track progress on the targeted completion dates stated for the ingot-wafer complex (December 2027) and BESS facility (June 2027).

The company has already made its direction clear: expand capabilities across manufacturing and downstream EPC, while building storage as a meaningful business line over time.
