Within the National Capital Region (NCR), Public Services and Procurement Canada (PSPC) is responsible for heating 80 buildings and cooling 67 buildings. As part of PSPC’s activities, the Energy Services Acquisition Program was established in 2009 to explore new business models for the provision of energy services in the NCR. The modernization project is looking for an energy services solution for PSPC’s five central heating and cooling plants (CHCP) and their associated distribution networks within the NCR. By 2027, the entire District Energy System will be modernized and converted from an energy-intensive and high-polluting steam system to a state-of-the-art low-temperature hot-water system, reducing greenhouse gas emissions from heating and cooling operations by an estimated 92 per cent.
