TLC works with customers to improve tree safety around power lines
10 November 2022
Vegetation close to power lines can be a danger to the public and can cause interruptions to power supply, especially during high winds and storms.
One of the leading causes of power outages is trees contacting power lines. To address this issue, TLC is working alongside customers to safely manage tree growth.
Vegetation encroaching on power lines presents a real danger to the public and can cause interruptions to customers’ power supply, especially during high winds and storms. Branches meeting lines can cause power outages, fires and can even electrocute people or livestock. In some cases, overgrown trees prevented TLC’s line mechanics from repairing equipment safely and quickly, ultimately delaying the process of restoring power.
For the period 1 April through to 19 September 2022, there were a total of 62 vegetation related outages. The average duration customers were without power for each outage was approximately three and a half hours.
To reduce damage and disruption caused by trees, TLC continues to prune and fell trees that obstruct lines and infrastructure. They continue to work alongside customers to control vegetation on the network and educate people on planting and trimming trees near power lines.
Vegetation Manager, Jason Gaukrodger says, “to be able to supply a reliable network to TLC customers our lines need to be free from interference. Supply to our customers is often interrupted by trees”.
“The safety of our customers is our top priority; if you have a tree near power lines that needs trimming or felling, it is best to contact us, and we will come out and discuss the options to sort out the tree. In certain situations, we may cover the cost of the first cut or trim.’’
“The best advice we can give people on our network is prevention is the best solution. Plan where you plant your trees in relation to power lines and trim your trees regularly before they encroach close to power lines”, said Gaukrodger.
With the tree owner responsible for keeping their trees pruned and away from overhead lines – TLC will issue a Cut or Trim Notice if a tree is encroaching the growth limit and require the tree owner to have the tree trimmed.
The company is actively working with tree owners to ensure safety is maintained and power outages are minimised. TLC encourage customers to get in touch if they have a tree related inquiry.
