The $25 million upgrade of the Mudgereeba Substation on the Gold Coast has been completed.
The upgrade was scheduled to improve the security and reliability of the electricity supply for the Commonwealth Games in April.
Queensland Energy Minister Dr Anthony Lynham said the upgrade would also improve stability of supply for the wider Gold Coast region into the future.
“Mudgeeraba Substation and Molendinar together are the two main power supply hubs for the Gold Coast,“ he said.
“The completion of the upgrade ensured electricity supply was as safe and secure as possible at a time when the eyes of the world were on the Gold Coast.
“The upgrade supported up to 50 local jobs and has extended the life of the infrastructure in a safe, and cost-effective way.
“Importantly, after more than 40 years of service already, Mudgeeraba can now continue to provide a reliable electricity supply for many years to come as the Gold Coast grows.”
Work began in 2016 and involved an upgrade of primary and secondary systems, including installing a new 250MVA transformer to replace the old, which was more than 40 years old.
The works also included control building and fencing.
Powerlink chief executive Merryn York said the team had focused on meeting deadlines and ensured major components of the upgrade were completed before the Commonwealth Games.
