Renewable energy trade shows in the USA cover very different markets, from utility-scale solar and storage to wind, hydropower, geothermal, hydrogen, batteries, and regional clean-energy development. This calendar lists selected renewable energy expos in the USA with organizer-confirmed dates as of September 2, 2026, then compares their content and exhibit opportunities.
Renewable Energy Trade Show Calendar at a Glance
The following 18 events have published dates and an exhibit, sponsor, or show-floor opportunity. They are arranged chronologically and labeled as core, specialist, regional, or adjacent events so that a broad power conference is not presented as if every attendee works in renewable energy.

September 2026: AEE World, Geothermal Rising, Clean Currents, and ACP RECHARGE
Four September events overlap, but their audiences range from broad energy management to geothermal, hydropower, and storage.
AEE World Energy Conference & Expo
AEE World covers energy efficiency, decarbonization, and energy management. It fits solutions that connect renewable generation with building, facility, industrial, or management decisions, but it is an adjacent event rather than a pure renewable-energy expo. The Orlando conference is listed for September 16–18 and the expo for September 16–17, so base staffing on expo hours.
Geothermal Rising Conference
The Geothermal Rising Conference runs September 20–23 in Houston. It is a focused match for geothermal development, drilling, subsurface analysis, heat-transfer systems, pumps, controls, engineering, and related services. An equipment display should show whether it supports exploration, well construction, surface facilities, generation, or operations.
Clean Currents
Clean Currents runs September 21–25 in Phoenix and centers on hydropower equipment, controls, inspection, maintenance, environmental services, and engineering. Current terms list exhibit-hall activity for September 23–24. Confirm weight, utilities, handling, and demonstration requirements before shipping a display.
ACP RECHARGE
ACP RECHARGE takes place September 22–24 in Aurora, Colorado. Among battery energy storage trade shows, it is a focused option for storage policy, financing, safety, technology, and operations. A cell, enclosure, thermal-management component, monitoring platform, or service needs a clear application and proof path.

October 2026: Hydrogen Americas, The Battery Show, and ASES SOLAR
October moves from hydrogen to batteries and solar, with different technical audiences at each event.
Hydrogen Americas Summit & Exhibition
Hydrogen Americas is scheduled for October 6–7 in Houston and includes a commercial exhibition. Among hydrogen conferences in the USA, it is directly relevant to production, infrastructure, equipment, projects, engineering, and safety. Operational displays require organizer review of dimensions, weight, energy inputs, heat, noise, and interaction before design is frozen.
The Battery Show North America
The Battery Show North America runs October 12–15 in Detroit, with the expo October 13–15. It covers battery materials, manufacturing, testing, thermal management, components, recycling, and EV technology. Stationary storage creates a renewable-energy overlap, but the event is adjacent rather than a pure renewable-energy show. Shortlist it only when your solution belongs in the battery or electrification chain.
ASES SOLAR 2026
ASES SOLAR 2026 takes place October 19–21 in Austin and spans solar research, applications, education, projects, and policy. It is a specialist conference with sponsor and exhibit options, not a substitute for every large solar expo. Check its attendee profile and exhibit format before using the assumptions prepared for RE+ or IESNA.

November 2026: RE+ 2026 in Las Vegas
RE+ 2026 is scheduled for November 16–19 at the Las Vegas Convention Center. Full conference education runs November 16–18, while exhibits and show-floor activities run November 17–19. The event covers solar, energy storage, hydrogen, EV infrastructure, grid-edge technology, microgrids, and wind power.
RE+ suits solutions that cross technologies or need a national clean-energy audience. Its breadth also makes “renewable energy” too broad for booth messaging; visitors should see the solution category, application, and decision point first.
RE+ is also the event most closely connected to the older Solar Power International name. The organizer's official FAQ states that RE+ evolved from SPI, ESI, and Smart Energy Week, so SPI and RE+ should not appear as two separate 2026 events in a current calendar.

January 2027: POWERGEN International and RE+ Hawai‘i
For teams researching energy trade shows for 2027, January starts with two different options: broad power generation and Hawaii’s regional clean-energy market.
POWERGEN International
POWERGEN International is scheduled for January 18–21 in Salt Lake City. It covers generation, utilities, plant technology, operations, and the energy transition. Choose it when your offering connects to generation assets or mixed power portfolios, but verify the relevant exhibit zones because the event is wider than renewable energy.
RE+ Hawai‘i
RE+ Hawai‘i is listed for January 26–27 in Honolulu and focuses on Hawaii policy, projects, solar, and storage. It is useful when regional conditions matter more than national attendance. Because the organizer page has contained historical material beside the 2027 date, use the latest contract and schedule for the final decision.
February 2027: RE+ Northeast, IESNA, and ACP OMS
Among clean energy conferences in 2027, February offers a regional market event, a large solar-and-storage show, and an operations-focused conference.
RE+ Northeast
RE+ Northeast is scheduled for February 2–4 in Boston and covers regional solar, storage, hydrogen, grid-edge technology, and EV infrastructure. It fits region-specific project, policy, deployment, and partnership discussions; confirm the latest attendee and exhibitor mix before shaping the message.
Intersolar & Energy Storage North America
IESNA is scheduled for February 9–11 in San Diego. For teams comparing solar trade shows in the USA, it connects solar and storage with manufacturing, supply chain, and EV infrastructure. Modules, inverters, racking, storage systems, equipment, software, and services should be shown in their system context.
ACP Operations, Maintenance & Safety Conference
ACP OMS is scheduled for February 23–25 in Long Beach and focuses on clean-energy operations, maintenance, and safety. It fits asset reliability, inspection, field tools, monitoring, maintenance planning, and operational-performance solutions. Lead with the task or failure mode, then support the technical discussion with evidence.

Spring 2027: RE+ Texas, RE+ Southeast, and CLEANPOWER
Spring combines two regional RE+ events with the national, multi-technology CLEANPOWER conference.
RE+ Texas
RE+ Texas is scheduled for March 24–25 in Houston. Its stated scope includes solar, storage, hydrogen, microgrids, and wind in the Texas market.
Shortlist it when your pipeline, partnerships, or technical application is tied to Texas. Use a relevant regional application rather than a shortened national-show message.
RE+ Southeast
RE+ Southeast is scheduled for May 11–12 in Atlanta and focuses on clean-energy development in the Southeast. It offers a more concentrated regional setting than the flagship RE+ event.
Compare its current company and job-function mix with the action you need after the show. A smaller regional footprint works only when the audience matches your market.
CLEANPOWER 2027
CLEANPOWER is scheduled for May 24–27 at the Anaheim Convention Center and spans wind, solar, storage, transmission, development, and operations. It is a core option when researching wind energy conferences in the USA or broader utility-scale clean power. A narrow solution still needs precise positioning.
June to November 2027: IESNA Midwest and RE+ 2027
Later clean energy events in 2027 include IESNA Midwest in June and the flagship RE+ event in November.
IESNA Midwest
IESNA Midwest is listed for June 14–16 in Rosemont, Illinois. Compare it with San Diego by region, company mix, and project relevance. When Midwest installers, developers, manufacturers, or service partners are central, regional concentration may be more useful than a larger audience.
RE+ 2027
RE+ 2027 is listed for November 15–18 in Las Vegas. Use the date for early planning, but recheck show-floor hours, exhibitor rules, and program details when 2027 materials are released. You can still identify possible products, demonstrations, space, and services without treating unconfirmed details as final.
How Do These Renewable Energy Trade Shows Differ by Content?
The 18 events fall into four useful content groups. This classification helps you avoid treating every event with “energy” in its name as the same sales environment.
| Event type | Examples from this calendar | Main content | When it deserves a closer look |
|---|---|---|---|
| Core event | RE+, CLEANPOWER, IESNA | Multiple renewable technologies or a major solar-and-storage market | Your solution crosses technologies or needs broad market coverage |
| Regional event | RE+ Hawai‘i, Northeast, Texas, Southeast; IESNA Midwest | Clean-energy topics within one geographic market | Your projects, partners, or account plan are regionally concentrated |
| Specialist event | Geothermal Rising, Clean Currents, RECHARGE, Hydrogen Americas, ASES SOLAR, ACP OMS | One technology or operational discipline | Your solution solves a clear problem in that technical chain |
| Adjacent event | AEE World, The Battery Show, POWERGEN | Energy management, batteries and EVs, or broad generation | The adjacent sector contains your required audience and applications |
A smaller specialist event can outperform a national show when every useful conversation starts with the same technical problem.
Which Renewable Energy Trade Show Fits Your Market?
Start with the market and technical decision your exhibit needs to support:
- Technology fit: Identify the exact application, system position, or operational problem your solution addresses.
- Audience fit: Check current exhibitor categories, attendee job functions, participating companies, and session themes.
- Geographic fit: Decide whether you need a national audience or a region such as Texas, the Northeast, Southeast, Hawaii, or Midwest.
- Exhibit fit: Confirm that the event offers the floor format, meeting environment, and display permissions your product requires.
- Next-step fit: Define what should happen after a useful conversation: a technical review, sample evaluation, project meeting, demonstration, or partner discussion.
| Your priority | Events to compare first | Evidence to check before deciding |
|---|---|---|
| Broad national clean-energy reach | RE+ and CLEANPOWER | Technology mix, exhibitor categories, attendee functions, and show-floor format |
| Solar and storage supply chain | IESNA, IESNA Midwest, and relevant RE+ events | Solar/storage exhibitor mix, manufacturing content, and regional coverage |
| A specific technology problem | Geothermal Rising, Clean Currents, RECHARGE, Hydrogen Americas, ASES SOLAR, or ACP OMS | Current technical tracks, participating-company types, and exhibit rules |
| One regional market | RE+ Hawai‘i, Northeast, Texas, or Southeast | State and regional project themes, company mix, and meeting objectives |
| Wider power or electrification context | AEE World, The Battery Show, or POWERGEN | The exact renewable-energy overlap and whether it contains your required audience |

What Should You Verify Before You Reserve Exhibit Space?
Verify the commercial exhibit opportunity separately from the conference headline. At minimum, check:
- The current exhibitor prospectus, floor plan, contract, and cancellation terms.
- Full conference dates versus move-in, show-floor, and move-out dates.
- Exhibitor categories, prior or current company lists, attendee functions, and session tracks.
- Booth dimensions, height limits, sightline rules, hanging-sign rules, and official-service requirements.
- Approval requirements for batteries, powered equipment, liquids, compressed gases, heat, noise, rotating parts, heavy equipment, or live demonstrations.
- Electricity, internet, AV, rigging, material handling, labor, installation, storage, and return-freight responsibilities.
Send the organizer a complete description of any operational display. Approval for one event does not establish approval at another venue or under another show’s rules.
How Should You Plan the Exhibit and Brief Your Booth Partner?
Once you have shortlisted the right event, the next step is to translate its audience, venue rules, demonstration requirements, and show objectives into a workable exhibit brief.
A renewable-energy exhibit should help a visitor understand four things quickly: what the solution is, where it belongs, what evidence supports it, and what should be discussed next.
Build the main message around one application and one decision. Replace broad words such as “innovation,” “sustainability,” and “future” with a specific system, project stage, operational task, or performance question. Give physical products context through scale, installation position, interfaces, cutaways, samples, or a simple system diagram. Present performance data as a short proof path rather than filling a wall with unrelated charts.
The floor plan should support the same logic. Use the front edge to establish relevance, give demonstrations enough viewing and operating space, and keep technical meetings away from the main traffic path when detail or confidentiality matters. The layout should follow the product and conversation—not a generic open-booth formula.
Before pricing, send your booth partner:
- Event name, city, dates, booth number, size, and configuration.
- Current exhibitor manual, floor plan, organizer contact, and required deadlines.
- The audience, application, and next action the exhibit must support.
- Product, sample, crate, and demonstration dimensions, weights, and operating state.
- Power, internet, AV, lighting, rigging, water, air, heat, noise, and safety information.
- Graphics, interfaces, evidence, samples, meeting needs, and content approval status.
- Budget range, approval date, freight origin, return destination, and reuse plan.
- Required design, production, logistics, installation, onsite, dismantle, and storage support.
These inputs allow design, production, shipping, official services, and installation responsibilities to be separated before the price is compared.

Frequently Asked Questions
What is the largest renewable energy trade show in the USA?
RE+ is the clearest answer under the organizer’s current clean-energy-show metric. The official RE+ FAQ reports 37,000 attendees and 1,350 exhibitors at RE+ 2025 and describes it as North America’s largest clean-energy show. That scale does not automatically make it the best event for every technical niche; compare its audience and content with your application.
What solar energy trade shows are happening in the USA in 2027?
Organizer-confirmed 2027 options in this calendar include RE+ Hawai‘i on January 26–27, RE+ Northeast on February 2–4, IESNA in San Diego on February 9–11, RE+ Texas on March 24–25, RE+ Southeast on May 11–12, CLEANPOWER on May 24–27, IESNA Midwest on June 14–16, and RE+ on November 15–18. Their scope ranges from regional solar markets to large multi-technology clean-energy events, so solar presence should be verified against the current program and exhibitor categories.
Where will RE+ be held in 2026?
RE+ 2026 will be held at the Las Vegas Convention Center in Las Vegas, Nevada, from November 16–19, 2026. Full conference education is scheduled for November 16–18, while exhibits and show-floor activities are scheduled for November 17–19.
Is Solar Power International the same event as RE+?
Solar Power International is part of the history of today’s RE+ event. The organizer's official FAQ says RE+ evolved from SPI, Energy Storage International, and Smart Energy Week. For a current 2026 calendar, SPI and RE+ should not be counted as two separate U.S. events.
Are renewable energy trade shows free to attend?
Not necessarily. Some organizers may offer a free or limited expo-only registration, while conference sessions, workshops, special events, or later registration tiers require payment. Exhibit space and sponsorship are separate commercial contracts. Check the current attendee registration page and exhibitor agreement independently before treating an event as free.
Final Thoughts
Choose a renewable energy trade show by matching its technology, regional market, audience, and exhibit format to your required conversation. Use this calendar to shortlist events, then confirm schedules, space, and display requirements in current exhibitor documents.
For booth planning, send KingExhibits the event, booth size, exhibitor manual, demonstration details, utility and AV needs, audience, budget, approval date, and required support. This helps separate design, production, logistics, official services, and installation responsibilities before production.
