Reliance's Green Energy Ambition: Massive Solar Giga Factory Rollout

Billionaire industrialist Mukesh Ambani is spearheading a green energy revolution with the sequential commissioning of five giga factories in Jamnagar and the rollout of solar energy production from the Kutch region in Gujarat. Reliance Industries Ltd (RIL) has already started producing solar photovoltaic (PV) modules from its new facility, with the first phase of the fully integrated solar manufacturing plant targeting 10 GW of renewable energy output for internal consumption.

The PV unit has already begun producing India’s most powerful solar panel, with a capacity of 720 watt-peak. This plant will be integrated with the broader solar value chain as the remaining construction phases conclude. Engineering and procurement for the full value chain are complete, and construction is progressing rapidly. Spanning over 5,000 acres in Jamnagar, the facility is equipped with advanced automation systems, including electro-luminescence inspection, robotic packaging, edge trimming, junction box mounting, and automated guided vehicles.

At the Dhirubhai Ambani Green Energy Giga Complex in Jamnagar, RIL is developing five giga factories focused on solar PV panels, fuel cells, green hydrogen, batteries, and power electronics. The company has allocated ₹75,000 crore for this AI- and robotics-enabled ecosystem. This solar project is part of a broader renewable strategy that includes battery energy storage and green hydrogen production. Leveraging vast arid lands in Kutch, an area known for high solar irradiance, the project aims to generate up to 150 billion units of electricity annually. Dedicated transmission infrastructure from Jamnagar is already in development.

In Kandla, RIL has earmarked 2,000 acres to build a green hydrogen ecosystem. Electrolyser manufacturing, in partnership with Norwegian firm Nel, is currently underway. The solar modules are based on Heterojunction Technology (HJT), noted for its superior efficiency. The facility has been designed with modularity in mind, enabling scale-up from 10 GW to 20 GW as demand increases. Speaking at the company’s last annual general meeting (AGM), Mukesh Ambani stated: “Our giga-factory is built for scalable expansion at minimal cost and with rapid timelines. We’ve fully integrated and localised HJT technology from REC Singapore, our wholly owned subsidiary, to develop next-generation bifacial solar panels with cell efficiency surpassing 26%.”

In parallel, RIL is constructing a 30 GWh battery manufacturing plant in Jamnagar. This facility will cater to both utility-scale and residential energy storage needs and will include backward integration into cell production and battery chemicals. According to Ambani, this will be the world’s first fully integrated battery giga factory capable of adapting across chemistries and applications. Additionally, the company is setting up a multi-gigawatt electrolyser manufacturing facility, scheduled for completion by 2026. It will support large-scale, cost-effective production of green hydrogen and fuels—further strengthening RIL’s leadership in the energy transition.
