Interior Transmission System Upgrades
We’re planning work on our natural gas system at a number of locations throughout the interior of British Columbia as part of our Interior Transmission System Upgrades project. Similar to the Coastal Transmission System Upgrades project, this work will further enhance the safety and reliability of the system we use to supply natural gas to more than 195,000 homes and businesses. Much of our work throughout Interior BC will take place at rural locations and will have minimal impact on residents and businesses.
Why we're upgrading these gas lines
Our Interior Transmission System includes more than 700 kilometres of gas lines and facilities that move gas throughout BC’s southern interior to communities in the West Kootenay, Okanagan Valley and South Thompson Valley. These lines have an excellent record for both safety and reliability because of the ongoing maintenance work we conduct.
The work planned as part of the Interior Transmission System Upgrades project will enhance our ability to monitor the condition of our lines by allowing us to use new, advanced inspection tools. We will build on our already robust inspection and maintenance activities, increasing our safety standards so we can continue providing reliable service to customers for decades to come.
We’ll be replacing sections of our gas lines and upgrading facilities to allow us to use new inspection tools in our Interior Transmission System. We expect worksites to range in size from about 2.5 metres to 50 metres long. This work will take place at 16 locations on and near existing FortisBC rights of way and facilities in BC’s interior.
Some work may impact nearby roads and paths. We will work directly with stakeholders, Indigenous groups, and nearby homes and businesses to identify and minimize disruptions.
We filed our regulatory application for this project with the BC Utilities Commission (BCUC) in September 2022. If approved, the majority of project construction work will occur in 2025-2026 in preparation for the line inspections that will begin in 2026.

Project timelines and next steps
In September 2022 we filed a project application with our regulator, the BCUC, and are expecting a decision in 2023. If approved, the majority of construction work will take place in 2025-2026 and baseline inspections will start in 2026.
We're in the early planning stages of this project and continuing to engage with local municipalities, Indigenous communities, landowners and local residents. We will continue to provide engagement opportunities throughout the project and can be contacted directly at [email protected].

Project application filed
Today marks a major step forward as we file our project application for a Certificate of Public Convenience and Necessity with the BC Utilities Commission (BCUC). The Interior Transmission System Upgrades project will update our natural gas system throughout the interior of British Columbia, enhancing existing safety and reliability.
While preparing to submit our application, we’ve been engaging local municipalities, Indigenous communities, landowners, and local residents to share details on the project and obtain feedback.
If approved, project construction work will occur in 2025-2026 in preparation for the line inspections that will begin in 2026.

Engagement underway to support project planning
We’ve started engaging with stakeholders, Indigenous groups and those living and working near the project worksites to gather feedback that will help us prepare our application for the British Columbia Utilities Commission (BCUC). We expect to submit our application to the BCUC in 2022. If approved, the construction will occur in 2024-2026 in preparation for line inspections that will take place 2025-2030.
Before construction takes place, we’ll work with communities, Indigenous groups, stakeholders and municipalities to minimize local disruptions.

What is the purpose of the Interior Transmission System Upgrades project?
The Interior Transmission System Upgrades project will enhance the safety and reliability of the system we use to supply natural gas to hundreds of thousands of homes and businesses. The work will enhance our ability to monitor the condition of our gas lines by allowing us to use new, advanced in-line inspection tools. These gas lines have an excellent record for both safety and reliability. The work being planned will build on our already robust inspection and maintenance activities, to make sure these lines continue to provide safe, reliable service for many decades to come.
