The RTC Summit will return to Washington, D.C. from October 16 – 17, 2025! Join us at the Westin Downtown for the premier event connecting leaders across the renewable thermal energy landscape. The RTC Summit is the only place where large industrial, institutional, and commercial energy users come together in person to accelerate renewable thermal solutions, connect with peers and renewable thermal providers, and overcome deployment challenges. The 2025 Summit will feature interactive discussions, buyer challenge statements, and expanded networking time.
