IDEA 2026

We are excited to bring the IDEA2026 Annual Conference & Trade Show to Ottawa, Canada, June 23-26 for three days of education, innovation and opportunities to connect. We're excited to convene an international audience in Canada's federal capital—not only to celebrate the remarkable progress driving district energy at home, but also to bring in global perspectives as we gather leaders from around the world to shape the industry's future. Ottawa—with its many groundbreaking, transformative projects already underway, from net-zero thermal networks and energy-from-waste solutions to campus-wide decarbonization initiatives—offers the perfect backdrop to explore how systems around the globe are advancing similar efforts. The educational program spans the most relevant topics in district energy today, including District Cooling & Thermal Energy Storage, Geothermal and Geo-Exchange, Thermal Energy Networks, De-Carbonizing with District Energy, and Smart Cities & Resilient Energy Infrastructure.
