Transmission line work powers ahead

Transmission line work powers ahead Some of the transmission towers being refitted on the Calliope River.

A $4 million project has begun to refit 21 high-transmission towers around Gladstone.

Member for Gladstone Glenn Butcher said works were underway to refit about 2km of existing transmission lines on an important link in Gladstone’s electricity transmission network – the connection from the Gladstone Power Station to the Calliope River Substation.

“The 21 towers being refitted have been exposed to harsh conditions as they are situated on the banks of the Calliope River and surrounding mangroves,” Mr Butcher said.

“Powerlink is undertaking the works in a staged approach to avoid impacts to electricity supply, maintaining reliability to both residential and industrial customers in the Gladstone region.’’

Energy Minister Dr Anthony Lynham said the project would continue through to 2021.

“This is an unusual project as a number of the towers are located on the banks of the Calliope River and were constructed using special ‘dolphin structures’ which allow the tower to sit above the high tide mark,’’ Dr Lynham said.

“Powerlink work crews use specialised techniques to safely and efficiently perform these activities on the over-water towers, including carefully scheduling work within tidal flows and utilising barges and helicopters to transport crews and equipment.”

Dr Lynham said the project would continue through to 2021.

Powerlink chief executive Merryn York said the refit project was the most cost-efficient solution to safeguard network reliability to the region.

“This work will extend the technical service life of this critical transmission line by around 10 to 15 years,” Ms York said.
