REI Expo + The Battery Show India 2026: One Venue, Two Shows, One Plan

On 22–24 October 2026, India Expo Mart in Greater Noida hosts two of the country's most important clean-energy events at once: Renewable Energy India (REI) Expo and The Battery Show India — both Informa Markets shows, running on the same dates at the same venue.

For exhibitors, that's not trivia. It changes where you book, what your stand says, and how far your budget goes. And unlike our recent show guides, this one comes with good news about timing: opening day is eight weeks away, which puts you exactly in the ideal booking window today.

The two shows at a glance

	REI Expo 2026	The Battery Show India 2026
Dates	22–24 October 2026	22–24 October 2026
Venue	India Expo Mart, Greater Noida	India Expo Mart, Greater Noida
Organizer	Informa Markets	Informa Markets
Focus	Solar, bio-energy, storage, green hydrogen, e-mobility	Battery technology, EV & energy storage supply chain
Official site	renewableenergyindiaexpo.com	thebatteryshowindia.com
Edition	Long-running flagship	4th edition

One honest caveat: the two official sites don't market a formal co-location — what's verified is same dates, same venue, same organizer. In practice, that means overlapping visitor traffic and one shared build-up period on the ground.

Which show is yours? (Sometimes it's both)

• Solar modules, EPC, inverters, hydrogen, wind-adjacent → REI is your floor.
• Cells, packs, BMS, charging, battery materials and manufacturing equipment → The Battery Show.
• Storage players sit in the overlap — an ESS company can justify either. The deciding question is who signs your purchase orders: project developers and EPCs (REI) or OEMs and pack manufacturers (Battery Show).
• Exhibiting at both? Some supply-chain companies do. If so, resist building two unrelated stands: one design language, scaled to two spaces, cuts cost and doubles brand recall for visitors who walk both floors.

Planning the stand for a clean-energy crowd

Show the hardware, prove the numbers

Clean-energy buyers are engineers and project-finance people in the same body. The stand needs the physical product — panels, cells, racks, chargers — plus the performance story presented legibly. A product wall with clear spec communication outperforms abstract brand graphics at every energy show.

Energy shows reward literal brightness

It sounds obvious, but lighting is the most underused weapon at renewable shows: a bright, white, energy-confident stand communicates the category promise. It's also the best cost-per-impact upgrade in the entire budget — a point we make in detail in the cost guide.

Two-show visibility

With parallel events, aisle traffic includes people who didn't come for you. A stand that states its category in three seconds — one headline, visible from distance — recruits from the neighbouring show's overflow. Height and corner positions are worth more this October than usual.

Your timeline from today

Eight weeks out is the sweet spot our whole booking guidance is built around:

• Now–early September: brief your builder, get concept and costing (ours arrives in 48 hours), lock scope.
• Mid-September: design freeze; organizer drawing submission per the exhibitor manual.
• Late September–mid-October: fabrication and mock-up test.
• Show week: build, handover, and three days of conversations that justify all of it.

Double-decker ambitions? That needs the 10–12 week runway — the decision is due this week, not next month. (The rules are here.)

Where we fit

6000+ stalls since 2002 across 9+ industries, delivered from a 30,000 sq ft workshop with 100% mock-up testing, fixed-price quotes and on-time delivery guaranteed in writing — at India Expo Mart and venues across India.

## FAQ

Are REI Expo and The Battery Show India the same event? No — two separate Informa Markets shows that run on the same dates (22–24 October 2026) at the same venue, India Expo Mart, Greater Noida.

Which show should an energy-storage company choose? Follow your buyers: project developers and EPCs → REI; OEMs and battery-pack manufacturers → The Battery Show. Companies serving both sometimes exhibit at both.

When should I book my stall builder for these shows? Now. At eight weeks out you're in the ideal 6–8 week custom window; a double-decker needs the decision immediately (10–12 weeks).

What does a stall at India Expo Mart cost? The India range applies: ₹7,000–₹25,000 per sq metre for custom design and fabrication depending on design, plus venue-specific logistics. Full breakdown in the cost guide.

What else runs at India Expo Mart in late 2026? Verified as of 15 August 2026: PMEC India (24–26 November) and INDIA ITME (4–9 December) follow at the same venue — relevant if you're planning a multi-show quarter.
