Renewable Energy India Expo (REI Expo) 2026 is a three-day clean energy trade exhibition held from 22 to 24 October 2026 at India Expo Mart, Greater Noida (Delhi NCR), for solar, wind, energy storage, green hydrogen, bio-energy and e-mobility manufacturers, developers, EPC contractors, investors and policymakers.
Organised by Informa Markets in India, REI Expo describes itself as Asia’s largest clean energy exhibition and has been running for well over a decade. The organiser says the 2026 show gives exhibitors access to more than 55,000 industry professionals across the renewable value chain. It is held alongside The Battery Show India 2026 at the same venue and dates, which adds a dedicated focus on cells, battery packs, materials and manufacturing equipment. Full listings are on MeetGrow’s REI Expo 2026 page.
What to Expect at REI Expo 2026
The exhibition spans solar PV modules, cells, inverters and trackers; wind components; battery energy storage systems (BESS); electrolysers and hydrogen production equipment; bio-energy and waste-to-energy systems; EV charging infrastructure; and balance-of-system products such as cables, mounting structures and module-cleaning robots. Past editions have featured live demonstrations of electrolysers, BESS units and trackers by large Indian developers and manufacturers.
REI typically runs a conference programme alongside the show, including CEO round tables and sector conclaves with central and state government participation, and country partner pavilions.

Why Energy and Manufacturing Professionals Shouldn’t Miss This Expo
India’s clean energy build-out is moving from generation to integration. Transmission and storage have become the bottlenecks, and the government’s recent clearance of Green Energy Corridor Phase III worth ₹1.86 lakh crore signals where investment is flowing next. Storage tenders, round-the-clock renewable contracts and battery manufacturing incentives are pulling BESS into the mainstream, while start-ups such as BatX Energies, which recently raised ₹105 crore, show investor appetite for battery recycling and materials.
For manufacturers, the shift to domestic content rules for modules and cells is changing supply chains, and for industrial users, falling storage costs are making round-the-clock green power more realistic. REI Expo, combined with The Battery Show India, is the most efficient place in the calendar to see these changes in one venue and meet the companies driving them.
