Transgrid to deploy synchronous condensers for NSW grid
Transgrid has announced that it has begun works to enable the installation of synchronous condensers on the NSW transmission network in order to support grid stability as the state energy grid transitions from coal to renewables.
The company will deploy a total of 10 synchronous condensers across five sites under the first phase of its System Strength Plan, following a NSW Government direction to accelerate procurement of this equipment as a Priority Network Infrastructure Project (PNIP).
Transgrid Executive General Manager of Network Jason Krstanoski said construction partners have now been engaged to carry out project-enabling works, which have already started at the first two priority sites in Newcastle and Kemps Creek.
“We are pleased to announce that Consolidated Power Projects (CPP) and UGL have been awarded contracts for the civil and building works to enable installation of the synchronous condensers,” he said. “By engaging two experienced delivery partners, we can progress works across multiple sites in parallel, helping ensure we meet the required timeframes to maintain system strength as the energy transition accelerates.
“Enabling works will be delivered by CPP at our Newcastle, Kemps Creek and Armidale substations and UGL at our Wellington and Darlington Point sites.
“These are complex civil and building works that we anticipate will take 12 to 14 months at each site, including earthworks, major foundations, underground services such as drainage, cabling and earthing, and construction of buildings housing electrical and communications systems.
“This work is being carefully sequenced to ensure we will be ready for our supply partner GE Vernova to begin installing the synchronous condensers as soon as they start arriving in Australia, currently expected from mid-2027.”
The synchronous condensers will be progressively installed and commissioned with a target of February 2029 for all units to be energised. Manufacturing of the synchronous condensers is also underway, with Transgrid representatives recently visiting GE Vernova’s UK plant to inspect production of the first unit.
