When the network is damaged, our first action is to make the site safe for our crews and for the community and then to assess the damage.
Our crews prioritise work focusing first on rebuilding the major lines that connect the most customers to the network.
After the major lines that form the backbone of the network have been repaired, crews work on the smaller lines and then on individual customer lines.
Major storms or lightning strikes often damage several sets of powerlines over a widespread area.
Ground and/or helicopter patrols must visually inspect lines before power is restored, to ensure it is safe to do so. In times of strong winds, aerial restrictions sometimes apply limiting our use of helicopter patrols.
As a result of these factors, restoring power to some regional areas can take longer.
