Reliance Industries will commence the production of solar photovoltaic modules at its giga-factory in Gujarat by the end of 2024. The first phase of its integrated solar production facilities includes modules, cells, glass, wafer, ingot, and polysilicon with an annual capacity of 10 GW.

The giga-factory is designed for modular expansion, and the capacity can be increased to 20 GW at minimum cost and time. “We have fully integrated and indigenized the HJT technology from REC Singapore, our wholly owned subsidiary, to develop 1 Gen bifacial solar panels with cell efficiency exceeding 26%,” Reliance Industries Chairman Mukesh Ambani told the company’s shareholders.

Ambani said Reliance had enhanced its R&D capabilities by establishing a state-of-the-art prototyping, testing, and validation lab in India and expanding its Advanced Solar Technology Lab in Singapore.

“This will also allow us to develop disruptive technologies like perovskites and back-contact HJT-IBC—which we have already demonstrated at pilot scale, with plans to commercialize them within the next two years,” he said.

The Dhirubhai Ambani Green Energy Giga Manufacturing Complex will be an integrated ecosystem at a single location. We are on track to fully commit and invest up to ₹750 billion (~$89 billion) to establish this manufacturing ecosystem, extensively enabled by all emerging technologies, including AI, IoT, Machine Learning, and Robotics.

BESS Manufacturing Facility

Reliance has begun constructing an integrated advanced chemistry-based battery manufacturing facility with a 30 GWh annual capacity at Jamnagar. Production will commence by the second half of next year.

Ambani said the facility will start by assembling Battery Energy Storage Systems (BESS) for utility-scale applications and pack solutions for residential, commercial, industrial, telecom, and mobility markets. “Progressively, over the next few quarters, we will integrate backward to cell manufacturing and eventually to battery chemicals production.”

The Reliance Chairman also said the company had begun work on a fully automated, multi-GW electrolyzer manufacturing facility on the west coast of India, which will be ready by 2026. This giga-factory will support various technologies such as alkaline, PEM, and AEM.

In May, Norway’s Nel Hydrogen Electrolyser announced a technology licensing agreement with Reliance Industries, granting it an exclusive license to manufacture and utilize Nel’s alkaline electrolyzers in India and for global captive use.

Reliance Electrolyzer Manufacturing was among the winners of Solar Energy Corporation of India’s tender to set up 1.5 GW of electrolyzer manufacturing capacities across India. Reliance won 300 MW capacity in the tender.

Round-the-Clock Renewable Energy

Significant project development work, including transmission infrastructure, was underway at Kutch. This will deliver stable and affordable round-the-clock renewable energy at GW scale, in a phased manner commencing 2026. “We have leased arid wasteland in Kutch, just 250 kilometers from Jamnagar. This wasteland has the potential to generate about 150 billion units of electricity in the next ten years — providing nearly 10% of India’s energy requirements,” Ambani said.

He also spoke about scaling up investments in bioenergy to reach 55 compressed biogas plants by 2025, which will help meet transportation fuel demand growth, foster sustainable rural development, and reduce LNG imports.
