RE+

RE+ (formerly Solar Power International / SPI) is the largest clean energy event in North America, produced by RE+ Events (Solar Energy Trade Shows, a division of SEIA and SEPA). The show brings together the full clean energy supply chain — solar PV, energy storage, wind, green hydrogen, electric vehicles, microgrids, inverters, racking, and more — across an expo floor, conference program, and networking events.

The flagship North American edition moves to the Las Vegas Convention Center in Las Vegas, NV for the 2026–2028 cycle. The next edition runs November 16–19, 2026, with subsequent editions confirmed for November 15–18, 2027 and November 13–16, 2028, all at the Las Vegas Convention Center.

RE+ is the annual anchor event for the U.S. renewable energy industry, drawing exhibitors, installers, developers, utilities, policymakers, and investors. Educational tracks span utility-scale and distributed generation, storage integration, grid modernization, and decarbonization strategy.
