RE+ celebrates its 20th anniversary in 2024! RE+ 24 brings the modern energy industry together to foster a cleaner future and marks its 20th year as the largest and most comprehensive event in North America for the clean energy industry. What began as Solar Power International (SPI) has evolved into RE+, uniting an extensive alliance of renewable energy leaders for multiple days of programming and networking opportunities. Today, RE+ incorporates business opportunities and education content across the clean energy industry including solar, energy storage, hydrogen, microgrids, EV charging and infrastructure, and wind energy.

Developed by the nation’s leading solar energy organizations, the Smart Electric Power Alliance (SEPA) and the Solar Energy Industries Association (SEIA), RE+ reflects an ongoing entrepreneurial approach to renewing best practices across the clean energy landscape as the marketplace evolves. Unlike other industry events, all proceeds from RE+ events support the expansion of the energy industry through SEIA and SEPA’s year-round research and education activities, and extensive advocacy and advisory efforts. Our primary mission is to deliver on the missions of both SEIA and SEPA in a way that strengthens the industry domestically and globally, through networking and education, and by creating an energetic and engaging marketplace to connect buyers and suppliers.
