During the IDEA Annual Chair’s Banquet at IDEA2022 on Monday, June 6, 2022, Enwave Energy Corporation was presented with the prestigious 2022 IDEA System of the Year Award for their submission, Toronto District Energy System.

It was a well-deserved win for the Enwave team, who also served as the official hosts for IDEA2022, the 113th Annual Conference & Trade Show for the International District Energy Association. The Toronto District Energy System is a shining example of the deep and lasting benefits that district energy systems provide for cities, communities and campuses around the world.  

Enwave’s Toronto District Energy System (EDES) in Toronto has been in continuous service since the 1950s. It features both a 1.6 PPH district steam and 49,000 Ton district cooling service to a wide variety of commercial, retail, residential, hospital, data center and event center customers.  Enwave recently revitalized its original 42,000 tons of deep lake water cooling heat exchangers with newer, more efficient equipment to achieve 0.3 Kw/Ton cooling performance.  It has posted a perfect 100% record for availability and reliability for the last two years.

Carlyle Coutinho, Chief Executive Officer and many from the Enwave team were on hand to accept the award. “Today is a very special day for us at Enwave,” noted Coutinho. “It is the one-year anniversary of our shareholders changing hands, a day that we formed what we affectionately call Enwave 3.0.  Our story at Enwave is a story about evolution and this award encompasses the joy we are having celebrating successes, learning, sharing, and connecting.”

As System of the Year Committee Chair, Bob Smith, Vice President of RMF Engineering rightly observed, “This impressive project from Enwave has influenced the next generation of thinking for district hot water heating by “harvesting” waste heat from customer buildings that don’t need it and transferring it to those who do, without burning more fossil fuels.”


IDEA President and CEO, Rob Thornton offered similar praise for this impressive, world-class system. “IDEA is proud to recognize Enwave Energy Corporation with the 2022 IDEA System of the Year Award, making Enwave the first IDEA member organization to have won this award three (3) times, previously in 1999 and 2011”, said Thornton. “Since its inception in 1993, the IDEA System of the Year Award winners have exemplified energy efficiency, environmental stewardship and outstanding customer service and reliability.  Enwave continues to evolve, introducing innovative technologies to support low-carbon solutions for the built environment in the fourth largest city in North America.”


Enwave is a leading provider of innovative, sustainable energy services. Enwave owns and operates district energy systems (DES) serving heating and cooling customers in downtown Toronto, Ontario, Canada. Enwave provides cooling to buildings year-around, servicing chilled water to downtown data centers and server rooms, running at or above a cooling load of 10,000 tons (or 120,000 MBH) all year -round. The “waste” heat from these customers was identified by Enwave as an opportunity to significantly reduce carbon emissions and further optimize their DES.

IDEA2022 was the 113th Annual Conference of the International District Energy Association.  Founded in 1909, as the National District Heating Association, IDEA continues to inform, connect, and advance the district energy industry around the globe. Today, the association has a membership of over 2,500 industry professionals representing more than 30 countries from around the globe.
