ESAP Stage 1 will result in the construction of some of the cleanest and most cutting-edge energy centres in North America:

The New Cliff Energy Centre – Reclaiming Public Realm in the Heart of Historic Ottawa

The Cliff Energy Centre is located next to the Supreme Court of Canada and will replace the original Cliff Heating and Cooling Plant. The project architects came up with an ingenious idea to transform a prime location that was formerly inaccessible to the public. The large energy facility will be below-grade of the Ottawa River escarpment’s upper plateau, allowing for an expansive urban park to be built over top, with new public realm and lush gardens. In order to preserve and enhance the historic profile of the Ottawa River’s south bank, the Cliff Energy Centre’s building envelope consists of an organically flowing "curtain" designed to screen and softly hide the mechanical facility.

The New Tunney's Pasture Energy Centre – A New Urban Park Replaces a Former Parking Lot

The Tunney's Pasture Energy Centre will be built in the northwest corner of the Tunney’s Pasture campus, replacing an existing parking lot. The building's modern exterior will include a sloping roof garden, a new park, footpaths through the site, and elevated views of the Ottawa River, contributing to the campus’ transformation from a single-use employment centre into a vibrant transit-oriented and sustainable mixed-use community. By creating a new publicly accessible realm in a space that was originally reserved for cars, the Tunney’s Pasture Energy Centre becomes one of the new faces of clean energy in Canada.

The Gatineau Energy Centre (GEC) – From “Grey to Green” in the Heart of Gatineau

The Gatineau Energy Centre (GEC) will be one of the most sustainable cutting-edge energy centres in North America. Located on a former surface parking lot next to the National Printing Bureau on Sacré-Coeur Boulevard in Hull, Gatineau, the facility will be built mostly underground, allowing for the space over top to be used as an expansive urban park, with lush gardens and courtyards. Connected to Hydro Québec’s clean electrical grid, GEC will provide carbon-neutral heating and cooling for buildings located along the district energy system’s network of underground pipes, in the cores of Gatineau and Ottawa.

A new pumphouse is also being constructed along the Ottawa River’s north shore to provide GEC with a green and renewable source of cold water for the energy centre’s cooling services. The facility’s green roof and naturalized landscape will blend in with the banks along the Ottawa River.

A Modern, Clean Energy Centre for a Revitalized Confederation Heights

The modernization of the Confederation Heights Energy Centre began in May 2020 and includes the conversion of the energy system from high-temperature hot water to low-temperature hot water and the replacement of older equipment with new, more efficient boilers and chillers. Work also includes the installation of a new roof and structural steel upgrades, and new underground pipes to connect the Energy Centre to other buildings at Confederation Heights. The result will be more efficient, reliable, and safer operations. As work on the Confederation Heights Master Plan progresses, the Confederation Heights Energy Centre will play a key role in transforming this car-centric federal employment campus into a vibrant, transit-oriented, sustainable mixed-use community.

ESAP’s modernized Energy Centres will be the new faces of clean energy globally – they will be architecturally pleasing, adding to the community’s use and enjoyment with gardens, courtyards, and improved connections for walking and cycling.
ESAP’s Stage 1 also includes the conversion and decommissioning of four older heating and cooling plants:
  • The Cliff Heating and Cooling Plant (over 100 years old)
  • The Tunney’s Pasture Heating and Cooling Plant (1953)
  • The National Printing Bureau Heating and Cooling Plant in Hull (1949)
  • The National Research Council Heating and Cooling Plant (1930).
