Undergrounding
Is undergrounding being considered?
We investigated the feasibility of an underground 500kV transmission line in response to community interest in undergrounding and the Environment Effects Statement (EES) scoping requirements.
We know undergrounding is something many in the community care deeply about. Unfortunately, it does not meet the project objectives and is therefore not a viable option for this project.
Underground cables don’t easily allow new renewable energy sources to connect along the route, which is one of the project’s goals. It would also take much longer to deliver and cost significantly more.
The EES explains why undergrounding does not meet the project objectives and is therefore not feasible for the Western Renewables Link.
