The Premier Clean Energy Event in North America
RE+, North America’s largest and most comprehensive clean energy gathering, is set to return to the Las Vegas Convention Center from November 16-19, 2026. What began as the Solar Power International (SPI) trade show has evolved into a powerhouse event that unites the full spectrum of renewable energy—solar, storage, hydrogen, wind, microgrids, and EV infrastructure.
The Scale of the Event
RE+ 2026 is expected to draw more than 37,000 attendees and over 1,300 exhibitors from around the globe. The exhibition floor spans approximately 30,000 square meters and hosts industry leaders including Tesla, LONGi, CATL, and Sungrow, alongside thousands of manufacturers, suppliers, project developers, utilities, and investors.
The event is jointly organized by the Solar Energy Industries Association (SEIA) and the Smart Electric Power Alliance (SEPA), two of the most influential organizations in the U.S. clean energy sector.
A New Addition: The RE+ Tech & Innovation Forum
A significant new feature for 2026 is the RE+ Tech & Innovation Forum, a two-day program presented in partnership with WIP Renewable Energies—the organizer of the EU PVSEC conference. This collaboration bridges North American and European expertise, bringing together applied researchers, technology innovators, industry leaders, and investors to accelerate the commercialization of emerging clean energy technologies.
The forum focuses on critical topics including:
- Next-generation cells and modules: back-contact, tandem, and perovskite technologies
- AI, digital twins, and virtual power plant architectures for bankable PV + storage portfolios
- Long-duration energy storage and technologies beyond lithium-ion
- Sustainability and circularity in PV manufacturing
- Building-integrated, mobility, and infrastructure-integrated solar applications
- Grid reliability and inverter-based resource integration
RE+ Storage: Focus on Energy Storage
RE+ Storage 2026, running June 30–July 1 in Sacramento, California, serves as a dedicated prelude to the main November event. This two-day conference unites the energy storage industry’s leading experts to explore manufacturing, supply chains, safety, resilience, and grid integration. Attendees include manufacturers, suppliers, engineers, utilities, grid operators, and project developers navigating the rapidly evolving storage landscape.
Built for Real Business
RE+ has evolved beyond a traditional trade fair to reflect how the modern energy system actually works—technologies are no longer isolated but combined across solar, storage, grid, software, and hybrid solutions. Attendees connect with decision-makers across the entire value chain, making it one of the most effective platforms for business development in the North American clean energy market.
International participation is robust, with international attendees comprising 35% of total visitors, and 70% holding purchasing or project decision-making authority. National pavilions from Germany and Denmark, among others, provide turnkey exhibition options for companies looking to enter the U.S. market.
Looking Ahead
RE+ 2026 reaffirms its position as the essential gathering for the clean energy industry. As renewable energy continues to scale and integrate into the broader power system, RE+ provides the platform where innovation meets execution—and where the future of energy is built.
