Abstract
The extensive electricity transmission network of Queensland is managed by Powerlink and has a significant exposure to both thunderstorms and tropical cyclones. In coastal North Queensland tropical cyclones (TC) dominate the severe wind hazard environment whereas in South East Queensland both storm types contribute significantly. Some parts of Powerlink’s network have high concentrations of older tower assets such as in the Gladstone region which supply electricity for the smelting and refining of aluminium. Other parts provide vital transmission links with limited redundancy between regions of generation in the south to large communities to the north, such as in far-North Queensland. These assets have been developed over many years, to design standards that have progressively changed, and some have been exposed to corrosive environments that are characteristic of the warm and humid coastal tropics. As a consequence of these factors, some assets within the system are particularly vulnerable to severe wind.
