PRES: What's happening
What are we building?
After exploring a number of options, we've identified a preferred alternative. It includes building two parallel 230 kilovolt (kV) transmission lines (approximately 58 kilometres in length). These transmission lines would run between the future Site C Substation near Fort St John and the new Groundbirch Substation, located about 30 km east of Chetwynd.
We're now doing further studies, design and consultation to develop this alternative in more detail.
Why we are pursuing this alternative
We compared alternatives against a number of criteria, including how easily and quickly it could be built; consultation feedback; estimated cost; and potential environmental and archaeological impacts.
This alternative has the shortest length, lowest cost, and would be the easiest to build. It avoids some important First Nations sites, requires the least amount of clearing and access road construction, minimizes visual impacts from communities and highways, and can be built in the shortest period of time in the safest manner.
Current and upcoming activities
The majority of our work is investigative in nature and is being done to help us finalize the route and design for the transmission lines. We are currently in the area working on:
- refining the preliminary transmission line route,
- developing access plans to the proposed transmission lines,
- developing clearing plans for the proposed transmission lines, and
- investigating geotechnical conditions along the proposed route.
We recently completed the centerline survey of the proposed transmission line route and archeological and environmental surveys.
Where is this happening?
We'll be working near the proposed transmission line route, which is shown on the map below. We're in the process of determining the best route for the transmission line. The route shown is not yet final and could change based on further studies and consultation.
