RE+ 2025 clocks 37k attendees, over 1,000 exhibitors

Here are three of the 37,000 RE+ attendees.

The final numbers are in: RE+ 25 brought together more than 37,000 industry professionals and 1,325 exhibiting companies in Las Vegas.

It was a slight dip from the record-breaking 2024 conference in Anaheim that saw 40,000 attendees.

“By welcoming more than 37,000 attendees this year, we’ve once again demonstrated why this is the largest and most influential clean energy tradeshow in North America. As the U.S. faces new challenges and rapidly rising energy demand, the leadership, collaboration, and innovation happening at RE+ 25 are critical to delivering the solutions to tomorrow’s needs,” said Stephen Miner, President and CEO, RE+ Events.

Solar Power World editors attended the landmark event and reported their findings here. 

This year’s International Showcase featured Denmark as the Spotlight Country, alongside pavilions for Germany, Canada, Austria, Türkiye and South Korea. The nearby Global Markets Stage drew strong crowds with sessions on international PV and energy storage opportunities.

RE+ 25 also partnered with organizations to host special on-site programming, including the 2nd Annual Agrivoltaics Showcase from the American Solar Grazing Association, the H2GP Sprint from the H2GP Foundation, the Clean Energy Job Fair presented by GRID Alternatives and Women of Renewable Industries and Sustainable Energy (WRISE), and the Grid Edge Theater, created and led by EMerge Alliance.

RE+ Events will return to Las Vegas for RE+ 26, November 16-19, 2026, at the Las Vegas Convention Center.
