Reliance Industries is set to commission the first phase of its 40 GWh battery gigafactory this year at its Dhirubhai Ambani Green Energy Giga Complex in Jamnagar, Gujarat, with a modular path to scale the site to 100 GWh per annum. Executive Director Anant Ambani laid out the timeline at the company's annual general meeting, calling the Jamnagar complex “unmatched globally in size, scale and integration.”
LFP For The Grid
The facility is designed to produce lithium iron phosphate (LFP) cells — the chemistry of choice for stationary grid-scale storage given its superior thermal stability and cycle life. When commissioned, Reliance will vault into the ranks of the world's largest LFP manufacturers, aligned to India's aggressive battery-storage tender pipeline. Manufacturing equipment has already been delivered to the Jamnagar site, with production ramp starting in the second half of 2026.
Solar, Hydrogen And Storage Under One Roof
Reliance's electrolyzer gigafactory is also on track to start production by the end of 2026, scalable to 3 GW per year, unlocking cost-competitive green hydrogen. The solar PV plant is already operational and has produced its first 200 MW of high-efficiency heterojunction (HJT) modules, with Ambani touting 10% higher yield, 20% better temperature tolerance and 25% lower degradation. The complex spans 44 million square feet — four times the size of the Tesla Gigafactory.
Global Ambition
Reliance is separately building one of the world's largest single-site solar projects in Kutch, Gujarat, spanning 550,000 acres, with 55 MW of modules and 150 MWh of battery containers deployed daily at peak construction. The company is targeting 3 million tonnes per annum of green hydrogen production by 2032, exporting green ammonia, methanol and sustainable aviation fuel. India's battery-storage market is heating up as regulators auction gigawatt-hours: state utility NTPC Green Energy last week continues its BESS push even as global battery deals accelerate.
