Transgrid has announced the completion of its $235 million Powering Sydney’s Future Project, delivering the largest 300kv cable project in Australian history.
Work began in August 2020 and was fast tracked by the New South Wales government in response to growing peak energy demand.
Transgrid CEO, Brett Redman said the $235 million project is the largest 300kV cable project delivered in Australia.
“This is the culmination of many years of planning, design and construction and will ensure a reliable electricity supply to more than 800,000 residents and the critical businesses and infrastructure helping to power the nation’s largest economy,” Mr Redman said.
“I’d like to thank the entire team behind PSF, despite the enormous challenges of the pandemic and building this infrastructure in some of Australia’s most densely populated areas, they’ve delivered this project on time and under budget.”
The completed project includes the installation of a new 20km 330kv underground cable between Potts Hill and Alexandria, upgrades to Transgrid substations, and the construction of cable bridges across rail corridors.
Additional conduits have also been installed to allow for the addition of a second cable pending future demand, Project Director, Colin Mayer said this would lessen disruption to local businesses and residences in the future.
“During construction we installed extra conduits which means when we need to put in additional cables in the future we can use those spare conduits and there will be much less disruption for residents and businesses,” Mr Mayer said.
He added that construction partners at Taihan and Garde, Zinfra, and GE helped meet technical challenges.
“It’s very satisfying that we delivered the project with great co-operation between our contractors and Transgrid – we worked as one team and we’ve delivered a great outcome for the people of Sydney,” Mr Mayer said.
