CLEANPOWER is produced by the American Clean Power Association (ACP), the national trade association for the U.S. clean energy industry. The event has grown into what ACP calls the clean energy industry's premier gathering, convening the wind, solar, storage, and transmission sectors under one roof. Recent editions have rotated among major U.S. cities; the 2026 conference was held in Houston, and the 2027 conference moves to Anaheim, CA. The show has expanded its programming over time to include dedicated networking tracks (EmpowHER, Emerging Leaders, PowerVets, CLEANPOWER in Color), multiple content stages, and an awards program.
