September 8-11, 2025

The largest clean energy event in North America just wrapped—and what a week it was.

This September, RE+ brought together 40,000+ clean energy professionals from around the globe—clean technology manufacturers, EPC professionals, electric companies, IPPs, and more—at the epicenter of collaboration and progress.

Now in its 21st year, RE+ has evolved from its origins as Solar Power International (SPI) into a one-of-a-kind experience that spans the entire clean energy ecosystem—encompassing solar, storage, hydrogen, EV infrastructure, microgrids, and wind.

Hosted by SEPA and SEIA, RE+ showcases a resilient and rapidly growing industry. Beyond the show floor, every connection made and lesson learned helps accelerate the transition to a carbon-free energy future. All proceeds go directly back into SEPA and SEIA’s year-round work, from research and education to convenings and advocacy.
