London District Energy Infrastructure Project

London District Energy’s roots date back to the establishment of a central steam heating plant in 1878. In the past seven years, LDE has invested over $50 million in continuous upgrades to enhance the steam system’s reliability and efficiency.

London District Energy system is a network of insulated underground pipes used for providing centralized heating and cooling to multiple buildings in an area, such as downtown London. At the heart of this system is a central production facility, located at Bathurst and Colborne streets, which generates thermal energy. This energy is then distributed to various buildings, where it's used for heating in winter and cooling in summer. 

London District Energy (LDE) is undertaking a significant transition of its steam heat system in downtown London to address reliability concerns.

After rigorous investigations, LDE has determined that, despite regular maintenance of the system equipment, portions of the steam system will become increasingly unreliable and may pose safety concerns in the future. As a result, LDE has made the difficult but necessary proactive decision to decommission parts of the LDE steam network.

As of May 31, 2025, our steam line within the boundaries shown on the map above will no longer be in service.

We will work with impacted customers to facilitate the switch to alternative heating sources.

After rigorous investigations, LDE has determined that, despite regular maintenance of the system equipment, portions of the steam system will become increasingly unreliable and may pose safety concerns in the future. As a result, LDE has made the difficult but necessary proactive decision to decommission parts of the LDE steam network. 

This decision underscores our dedication to maintaining the highest standards of safety, reliability, and efficiency in our operations.

The decommissioning process has been structured carefully to maintain continuity of service until decommissioning.

As of May 31, 2025, our steam line within the boundaries shown on the map above will no longer be in service. We began notifying customers within the identified zone on May 27, 2024, giving them ample notice to switch to alternative heating systems before the onset of the 2025/26 winter season.

The timing for the completion of the entire decommissioning process will depend on the complexity and scope, but we are committed to progressing efficiently and will keep all impacted stakeholders updated as we move forward.

Our strategy involves constant monitoring and evaluation of the entire steam network to ensure it adheres to safety and reliability standards. We are currently completing a thorough investigation of the remainder of the steam network. 

If future investigations highlight areas that pose reliability risks, we will take the necessary actions to either upgrade or decommission those sections to uphold the integrity and efficiency of our service delivery to customers.

As of May 31, 2025, the steam line within the boundaries shown on the map above will no longer be in service, impacting 17 customers. We began notifying customers within the identified zone on May 27, 2024, providing them ample notice to switch to alternative heating systems before the onset of the 2025/26 winter season.

We continue to assess the reliability of other portions of our steam infrastructure and will provide ample notice to customers impacted by any future plans.

LDE has informed reputable third-party heating service providers about the disconnections. These providers are ready to work with affected buildings to set up new heating services. A Community Liaison and a Project Manager will assist customers throughout the transition. Customers are free to choose recommended providers or select their own based on personal preferences and needs.

No, we will not disconnect your heat during the winter months. The actual service disconnection will occur on May 31, 2025, well before the onset of cold weather. All customers have ample time to prepare well before the 2025/2026 heating season.

During this period, you will also have access to a dedicated Community Liaison and a Project Manager who can assist you in transitioning to new in-building heating solutions.

You will have access to a dedicated Community Liaison and a Project Manager who will guide you through the process of transitioning to in-building heating solutions. This support is tailored to those who need detailed assistance throughout the transition.

If you prefer to manage some aspects of the transition independently, our team is flexible and can adjust the level of support provided. We are here to assist as much or as little as you require, depending on your specific needs and preferences.

No, you are not required to switch to the providers we will present to you. 

While the reputable providers we suggested are ready and capable of servicing your area, you have the freedom to choose any supplier that best meets your personal needs and preferences. 

No, the decommissioning of steam lines will not impact your chilled water services. Your service will continue without interruption.

The construction involved in our decommissioning process is limited and will primarily take place in public areas. We will work closely with the City to ensure that all construction activities are carried out with the necessary permits and adhere to stringent safety measures.
