Thermal Energy Networks (TENs)

Understanding the Potential of TENs

Thermal Energy Networks (TENs) may offer a promising alternative to traditional building-by-building decarbonization approaches in certain circumstances. To better understand the extent of their potential, our TENs initiative is leading several projects to clarify the techno-economic opportunities they present, and to explore ways to integrate these approaches into municipal, provincial, and federal regulations if and where appropriate.

Why do TENs matter?

Decarbonizing Canada’s buildings in time to meet our 2050 obligations will call on us to use every credible tool in our arsenal. While the BDA believes heat pumps in all their forms are the most promising tool for reducing emissions from building heating, TENs (which themselves can also rely on heat-pumps) could be an important complement to that pathway. Given their potential high performance, climate resilience, economies of scale, reduced peak electricity demand impacts, and very low greenhouse gas (GHG) emissions, TENs represent a promising solution for decarbonization beyond a building-by-building level. What’s more, the planning approaches that facilitate TENs can help foster a better managed, more affordable energy transition. However, many challenges remain before they can be adopted at a meaningful scale, particularly in the context of existing buildings and neighbourhoods.

Our Projects

There are many open questions about the appropriate implementation of TENs. The projects in this initiative will address those gaps from a variety of perspectives, combining in-depth analysis with insights from expert advisors to help Canada’s building sector understand where and how to best use these tools.

Developing Thermal Network Impact Potential and Advancing Regulatory Prototypes

Estimated Timeline: 2024-2026

Description: The Building Decarbonization Alliance has launched a national study on the potential of Thermal Energy Networks, a two-year project aimed at developing analysis, decision-support tools, and prototype policies that might help expand the consideration and deployment of TENs as a complement to other building-by-building decarbonization solutions when conditions support them.

While TENs are a promising solution for neighbourhood-scale decarbonization, the area-based planning approaches that are needed for them to reach scale are only just emerging in Canada. This project aims to clarify the economic opportunities associated with TENs and area-based planning approaches, and to find ways to embed those approaches into regulations at the municipal, provincial, and federal level. Ultimately, we aim to provide analysis, decision support tools, and prototype policies that can help broaden the use of TENs where appropriate as a complement to other building-by-building decarbonization tools.

Unlocking Utility-Scale Thermal Energy Networks in Canada

Estimated Timeline: 2025-2027 

Description: This project’s objective is to enable utilities to deploy Thermal Energy Networks (TENs). Large utilities (i.e., electric and/or natural gas) have the necessary infrastructure, expertise, and relationships to efficiently manage and scale these complex systems to ensure reliable energy distribution. Utilities can leverage their resources and capabilities to integrate renewable energy sources, reduce emissions, and achieve broader sustainability goals while maintaining affordability for their customers. While four U.S. States recently passed legislation to either allow or mandate their utilities to develop TEN demonstration projects or pilots, Canada has seen far less utility activity in the TENs space. Current regulations do not fully support the integration of TENs, limiting the potential for improved heating efficiency and lower emissions. This project will see us work enable utilities to implement TENs by conducting a comprehensive review of existing regulations, identifying blockers, and collaboratively developing potential regulatory solutions and working to have them implemented toward utility-led pilots.

Road-mapping Initiative for Networked Geothermal (RING)

Estimated Timeline: 2024-2025 

Description: From fall 2024 through spring 2025, the Building Decarbonizaton Alliance will be taking part in a working group of industry and regulatory experts led by MaRS, with the goal of exploring how to accelerate the deployment of affordable, reliable, utility-scale geothermal networks in high-density Canadian cities that rely heavily on natural gas for heating.
