RE+ 2026

RE+ bills itself as the largest clean energy event in North America. It is produced by the Solar Energy Industries Association and the Smart Electric Power Alliance, and it is the successor to Solar Power International, Energy Storage International and Smart Energy Week. Coverage spans solar, energy storage, wind, EV infrastructure, hydrogen and fuel cells, microgrids, grid-edge technology, geothermal and biomass. It is a business event throughout: developers, EPCs, installers, contractors, utilities, manufacturers, engineering firms and project financiers, not a public expo.

The 2026 show takes the West, North and Central halls of the Las Vegas Convention Center. Exhibitors are module, inverter, racking, battery and balance-of-system manufacturers, EPC and O&M contractors, software and asset-management vendors, and finance and insurance providers, with heavy international representation. RE+ publishes booth rates openly at $52 per square foot, or $42 for RE+ sponsors and premium SEIA and SEPA members. Note that the exhibit halls open a day after the conference program starts, which affects staffing and travel plans.

Ahead of the 2025 edition, RE+ told prospective exhibitors to expect over 40,000 energy professionals and over 1,300 exhibiting companies. Exhibitor badge allocations scale with booth size, from four passes at 100 square feet up to 96 at 3,200 square feet and above, which gives a fair sense of the range of stands on this floor.

Why RE+ matters

RE+ brings contractors, engineers, facilities teams, manufacturers, specifiers and buyers evaluating tools, materials and systems to Las Vegas Convention Center in Las Vegas. For SHOWFLOOR.TV, the value is not simply the size of the gathering. It is the concentration of people, products and decisions in one place—and the chance to see what holds up when a claim has to work on a real show floor.

The editorial case is strongest where this show offers useful floor-level reporting opportunities. That makes it a useful place to look beyond announcement language: what is being demonstrated, what visitors stop to examine, which questions buyers ask and which ideas are ready to move from presentation to practice.

What to watch on the show floor

A productive visit starts with observable signals. We will be looking for the booths, sessions and conversations that make the market easier to understand—not only the biggest builds or the loudest launches.

• full-scale demonstrations that reveal speed, durability and ease of use
• products that reduce labor, risk, waste or energy use
• technical comparisons grounded in measurable performance
• field experts who can discuss installation, support and total cost of ownership

Those signals help separate a polished display from a genuinely useful exhibit. The strongest stories usually have three parts: a clear problem, a product or idea that can be seen in action, and a person who can explain what happens after the demonstration ends.

For exhibitors: how to be useful here

A strong booth here is practical. Visitors should be able to see how the product works, understand where it fits in a real project and leave with specifications, contacts and a credible next step.

Media readiness matters, too. A concise company description, current product links, high-resolution approved photography, named spokespeople and a short list of verifiable claims make it much easier for an editorial team to report accurately. If a launch is under embargo, state the timing and terms plainly. If the story depends on a demonstration, schedule time when the right expert and the working product will both be present.

Exhibitors seeking SHOWFLOOR.TV consideration can use the update link below to share booth details, launch timing, interview availability and media assets. Submission does not guarantee coverage; specificity and verifiable information make a pitch substantially more useful.

For attendees: a smarter way to use the event

Start with the official exhibitor information and build a short priority list by problem or category, not only by brand recognition. Book the conversations that require a specialist, then protect unstructured time for discovery. On the floor, ask to see the product or process working, who it is designed for, what it replaces, what implementation requires and where the evidence can be reviewed after the show.

Before making travel or purchasing decisions, confirm the current schedule, badge rules and venue information with the organizer. Event programs change, and the official site remains the authority for registration, access and last-minute updates.

SHOWFLOOR.TV reporting brief

Our editorial lens for RE+ is practical: new products with a defined use case, demonstrations that reveal something a press release cannot, design choices that improve the visitor experience, and candid conversations with the people building or buying what is on display. We are especially interested in independent exhibitors, first-time launches, useful visual explanations and the gap between a market trend and what is actually happening in the aisle.
