The Enmax District Energy Centre is Alberta’s first District Energy Plant, a unique facility located in downtown Calgary. Graham, working closely with Enmax, its pre-purchased equipment suppliers and the design team, co-ordinated all major equipment deliveries including installation and commissioning to meet the owner’s timelines, all while respecting the overall budget and quality requirements of an urban site. Construction work included the cast-in-place concrete structure with two basements and a sub-basement, distribution pits, process piping, and electrical controls. All concrete work on the project was self-performed by Graham.

The 2,100m2 (23,000sq.ft.) plant has the capacity to provide central heating water for up to 930,000m2 (10 million sq. ft.) of residential and commercial buildings in the downtown core, distributed through a network of underground insulated pipes. City Hall was the first building connected to the plant, eliminating its own boiler system in the process. This project was the first for The City of Calgary and one of the largest non-institutional systems in Western Canada.
