Interior Transmission System Upgrades
About this project
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.
Construction overview

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 plan to file our regulatory application for this project with the BC Utilities Commission (BCUC) in 2022. If approved, project construction work will occur in 2024-2026 in preparation for the line inspections that will take place 2025-2030.

Project timelines and next steps
We're in the early planning stages of this project and engaging with local municipalities, Indigenous groups, landowners and local residents. We will continue to provide engagement opportunities throughout the project, and can be contacted directly at 1-888-486-0138 and interiortransmission@fortisbc.com.
Engagement began
BCUC application filing expected
BCUC decision expected
Construction
Gas line inspections complete
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.

Why are you working in the community during a pandemic?
As an essential service, we’re continuing to move projects forward that support the energy needs of our customers while adapting to the challenges of the COVID-19 pandemic. These upgrades are part of this critical work, so we can continue providing the reliable service residents and businesses count on.
Safety is at the heart of everything we do. While working in the community, our crews will continue to take appropriate physical distancing measures to ensure their safety, as well as the safety of area residents.
On the rare occasion physical distancing isn’t possible, our crews will have access to additional personal protective equipment such as respiratory, eye and hand protection, to further reduce the risk of infection.
Learn more about how we’re working safely during the pandemic.

Why is FortisBC still investing in natural gas instead of exploring cleaner energy solutions?
We’re exploring cleaner energy solutions like Renewable Natural Gas (RNG) and hydrogen. However, we expect natural gas will continue playing an important role in moving BC towards a lower-carbon future.
We’re focused on keeping affordable natural gas available to our customers, while lowering the carbon footprint of natural gas by increasing the amount of carbon neutral RNG. RNG is interchangeable with conventional natural gas. We can inject it into our natural gas distribution system, reducing the amount of conventional natural gas needed.
We’re aiming to produce 15 per cent of our natural gas supply with RNG by 2030. Sustainable energy sources like renewable gases will play a big part in helping us meet our 30BY30 target to reduce our customers’ greenhouse gas emissions 30 per cent by 2030.
