Distribution line surveys progressing along NWTD corridor

Surveys to assess undergrounding opportunities for 22kV distribution lines are now underway across the NWTD project corridor. These investigations are focused on locations where existing distribution lines cross proposed transmission lines - around 80 sites in total, stretching from Palmerston (near Cressy) to Burnie.

The surveys are helping TasNetworks identify where undergrounding distribution lines may be the safest and most practical solution. At transmission crossing points, maintaining minimum clearance distances between overhead lines can be difficult, costly, or even unviable. Undergrounding removes these clearance conflicts, reduces the risk of electricity jumping between power lines or to nearby objects (which can cause outages or safety issues), and improves compliance with safety standards.

Survey teams have been working closely with landholders to access sites and gather data. TasNetworks land agents, engineers, Genus field staff, and designers from Partum Engineering have all been involved, ensuring the surveys are thorough and respectful of each property.

Many landholders have welcomed the chance to discuss how the current distribution network affects their land and explore solutions that reduce impacts. Feedback has been positive, and the collaborative approach is helping shape designs that are safer, more cost-effective, and better suited to each site.

By replacing overhead distribution lines with underground infrastructure at key locations, TasNetworks aims to reduce outage risks, improve safety, and minimise visual and environmental impacts. Upon completion of the surveys, Partum Engineering will use the data to put forward new designs where required. These designs will be shared with landholders for further input.

TasNetworks thanks all landholders who have participated so far. Your feedback and cooperation are helping progress this important step in the NWTD project and ensure the best possible outcomes for both the community and the network.
