The commissioning of the new Enwave Green Heat™ Plant is a monumental step in further enabling Enwave to provide low-carbon heating through its Enwave Green Heat™ program to Toronto’s world-renowned district energy system. The plant has been designed to reduce its electricity demand during peak times while continuing to provide reliable, low-carbon heating and cooling—demonstrating the ability of district energy to enable the decarbonization and electrification of Toronto’s buildings while making more efficient use of Ontario’s electricity infrastructure.
“The commissioning of the new Enwave Green Heat™ Plant marks another step forward in providing low-carbon heating to more people in Toronto, leveraging the existing district energy system,” says Toronto Mayor Olivia Chow. “The city is grateful for Enwave’s continued partnership and ambitious approach to providing electrification solutions that further support innovation and sustainability and the City’s Transform TO goal of Net Zero by 2040.”
Enwave began development of the plant as an addition to the Pearl Street Energy Centre in 2018, initially breaking ground in May 2023. The 60-year-old Pearl Street Energy Centre has been updated with a three-story addition, including entirely new building façade and new community artwork. Once fully operational, the new plant will have capacity of 3,600 tons of cooling and 62,000 MBH of heating. The electrified heating generated from the plant will be capable of displacing carbon emissions of up to 11,600 tCO2e, as compared to traditional steam to hot water energy generation—which is the equivalent carbon reduction associated with converting 10 million square feet of existing office space from traditional boilers to low-carbon heating.
In an effort to provide decarbonization at scale, the plant will leverage waste heat from Enwave’s Deep Lake Water Cooling (DLWC) system customers—including data centres, hospitals, scientific research facilities and lab spaces – which is then upgraded through the electrified heat pump into hot water. This allows the plant to provide heat to other district-connected customers, while potentially reducing new electricity peak generation, distribution and transmission infrastructure that would otherwise be required, if heating was provided by stand-alone electrified solutions.
Enwave’s award-winning DLWC system and its Enwave Green Heat™ Plant directly support Ontario’s first Integrated Energy Plan, which aims to ensure that the Province of Ontario has the energy it needs to power homes and industries, today and in the decades to come.
The new plant will have a total electricity demand of approximately 6MW when it is serving its full thermal load and has been designed with the potential to reduce its peak electricity demand by up to 6MW – supporting the reliability of Ontario’s electricity system while continuing to meet the heating and cooling needs of Enwave’s thermal energy customers.
“The commissioning of the Enwave Green Heat™ Plant at our Pearl Street Energy Centre is a great example of how Enwave can contribute to the electrification of the economy more efficiently and cost effectively for all stakeholders in Toronto,” says Carlyle Coutinho, CEO of Enwave Energy Corporation.
“Expanding the offerings of our Enwave Green Heat™ program through this new plant allows customers commercial access to sustainable solutions at scale, serving even more residents, institutions and businesses in Ontario. In collaboration with the City of Toronto and the Province of Ontario, this approach to decarbonization helps enable our customers to meet the highest levels of Toronto Green Standards, while allowing us to work toward building a cleaner, brighter future. We are proud to be a partner of choice in the energy transformation to net-zero carbon.”
