Stage 1

The Energy Services Modernization (ESM) project involves the conversion of the Government of Canada’s district energy system in Ottawa and Gatineau to use low temperature hot water for heating and electric chillers for cooling. It also involves the implementation of the Smart Buildings program, and ISO 50001 certification.

Cliff Site Overview from June 7th2021

This stage began in 2019 and will run until 2025.

Stage 1 of the program will:
  • Convert the system from steam and high-temperature hot water to low-temperature hot water;
  • Switch from steam to electric chillers;
  • Use Smart Building technology to find ways to use energy more efficiency; and,
  • Manage the project’s energy performance using the standardized ISO 50001 certification as a baseline for the next 35 years.
The Energy Services Acquisition Program (ESAP) has already cut greenhouse gas (GHG) emissions by approximately 30% since 2005 and by 2025 total reductions will be 63% with the completion of Stage 1.
ESAP is expected to deliver a solution that will redefine and improve the delivery of heating and cooling services in the National Capital Region (NCR) and achieve the following objectives:
  • Improve the Government of Canada’s environmental performance;
  • Reduce the costs of heating and cooling operations;
  • Increase safety and reliability of heating and cooling operations;
  • Leverage the private sector’s innovation, capacity, and expertise;
  • Promote growth of the system throughout the NCR;
  • Become an architectural landmark at the Cliff and Tunney’s sites; and,
  • Integrate an education platform as part of system transformation and operation.
To address the sensitivity of the sites and the surrounding construction zones, Innovate Energy will implement tailored solutions considering construction activities, pedestrian paths, work duration and potential impacts to the public, neighbouring establishments, the fauna and flora. Several initiatives will be carried out to honor the NCR’s high-profile buildings and not distract from a visitor’s experience exploring the city, or impact vehicular traffic.
By the end of Stage 1, four central heating and cooling plants will remain, and one will be decommissioned:
  • The Cliff plant
    • The plant will be newly built
  • The Tunney’s Pasture plant
    • The plant will be newly built
  • The National Printing Bureau plant
    • The plant will be newly built
  • The Confederation Heights plant
    • The plant will be renovated
  • The National Research Council plant
    • The plant will be decommissioned
