Enwave Energy Corporation
District Energy System Cogeneration Plant
District energy is a key component of Toronto’s climate action plan, to reduce emissions from buildings and help the City reach its greenhouse gas (GHG) reduction target of 80% by 2050. Buildings currently generate about half of the GHG emissions in Toronto.
Enwave is the largest District Energy Systems in North America. The system has enough power to supply over 180 office buildings.
This project started in 1962 with an original feasibility study and culminated in the design and construction of a central plant and distribution system with an installed capacity of 800,000 lbs. of steam per hour.
The deep lake cooling system was added later, and makes use of the 40°F/4°C water in Lake Ontario. It has a total capacity of 75,000 tons of refrigeration, which is sufficient to air condition 3.2 million m2 / ~34 million ft2 offices.
Clients with whom we have worked on the Enwave District Energy System include:
