IDEA 2026 conference in Ottawa aims to advance sustainable district energy networks through international collaboration
The International District Energy Association (IDEA) has confirmed that its 117th annual IDEA Conference and Trade Show will take place from June 23 to 26, 2026, in Ottawa, Canada. The event is set to be held at the Rogers Centre Ottawa Convention Center, a venue well-suited to accommodate the diverse and dynamic nature of the gathering.
Themed "Connecting Networks," the conference aims to foster education, innovation, and collaboration among district energy professionals worldwide. This theme reflects the industry’s growing emphasis on integrating district energy systems and advancing sustainable energy networks to meet emerging environmental and urban demands.
The IDEA Conference program will feature a rich agenda including workshops, panel discussions, podium presentations, and poster sessions. These sessions will focus on pertinent and contemporary issues within district energy, featuring real-world case studies, addressing industry challenges and successes, and providing actionable insights to attendees. The comprehensive program is scheduled for release in early 2026, while IDEA has opened a call for presentations with abstracts due by December 12, 2025, encouraging broad participation from professionals wishing to share their innovations and expertise.
Exhibit booths are now available, offering companies, suppliers, and service providers the chance to showcase the latest technologies and solutions in district energy infrastructure and services. Registration for the event is expected to open later this year, providing an opportunity for industry leaders, innovators, and stakeholders to engage directly with emerging trends and network with peers.
IDEA's conference continues to be a pivotal event for executives and professionals involved in district energy, fostering a platform for advancing knowledge, building strategic partnerships, and driving the sector toward greater sustainability and efficiency. Hosting the event in Ottawa not only highlights the city’s growing role in the energy sector but also facilitates international participation given its strategic location in Canada’s capital.
With the energy sector's ongoing transformation driven by climate goals and the need for resilient energy systems, the IDEA2026 conference is poised to be an essential forum for dialogue, learning, and collaboration, helping members and stakeholders navigate the future of district energy systems worldwide.
