The $6.5 million project, aimed at securing the electricity network and improving safety, was funded by the State Government, Western Power and affected residents.
Coolbinia residents made a one off payment of more than $6100, representing 50 per cent of the related costs, with the State and Western Power each contributing 25 per cent.
Western Power acting chief executive Simon Walsh said the project would save the City of Stirling money in the future.
‘Households and local governments also save on the cost of tree trimming which is necessary this time of year to prevent branches damaging powerlines causing hazards in storms,’ Mr Walsh said.
Coolbinia is the latest suburb to complete the State Underground Power Program, a State Government initiative, offering councils an opportunity to nominate specific suburbs for the project.
City of Stirling Mayor Giovanni Italiano thanked those involved in the project and said he believed the project would increase property values.
‘It’s great to celebrate the successful completion of this project and I’d like to extend a big thank-you to everyone who made it happen,’ Cr Italiano said.
Underground power has also been installed in Mt Lawley, Woodlands and Wembley Downs and parts of Scarborough.
The City of Stirling dedicated $21,227.00 to the project to pay for powder coating of streetlights to suit the character of the area.
