Hunter Transmission Project and Renewable Energy Zone plans move forward
The NSW Government is progressing key energy projects in the Hunter region, with commitments from Transgrid and Ausgrid that will support the transition to renewable energy and create local employment opportunities.
The Hunter-Central Coast REZ is designed to provide 1 gigawatt of initial network capacity, with future expansions expected as coal-fired power stations retire and new technologies such as hydrogen develop. Separately, the Hunter Transmission Project could add up to 8 gigawatts of transfer capacity from inland renewable energy zones, supporting industries like Tomago Aluminium and emerging sectors.
With both projects moving ahead, the Hunter region is set to play a key role in NSW’s energy transition while generating job opportunities and investment in local infrastructure.
Hunter Transmission Project Advances
EnergyCo has signed a commitment deed with Transgrid for the Hunter Transmission Project, a high-voltage transmission line designed to strengthen the state’s electricity network. The 100-kilometre, 500-kilovolt (kV) line will connect Bayswater in the Upper Hunter to Olney in the Lower Hunter, forming part of a broader network upgrade that aims to support energy reliability as coal-fired power stations close.
Transgrid will be responsible for delivering, operating and maintaining the transmission line. EnergyCo has shortlisted seven contractors for key work packages covering transmission line construction and substations. Shortlisted companies include Acciona Genus Joint Venture, Downer Utilities Australia, Gamuda Seymour Whyte Joint Venture, UGL Engineering CPB Contractors Joint Venture, and Consolidated Power Projects Australia.
The project is expected to require around 700 workers, including engineers, electricians and labourers. EnergyCo is preparing final tender documents and will continue engaging with local stakeholders as planning progresses.
EnergyCo Chief Executive Hannah McCaughey said, “The Hunter Transmission Project is critical and must be delivered to unlock reliable energy supply to power the state.”
Transgrid CEO Brett Redman added, “The Hunter has been at the heart of our energy industry for decades and we look forward to continuing to work with the local community as the region continues to play an important role in the state’s clean energy transition.”
Hunter-Central Coast Renewable Energy Zone (REZ) Begins Consultation
The Hunter-Central Coast Renewable Energy Zone (REZ) has moved forward with Ausgrid appointed as the preferred network operator. The project will upgrade existing poles and wires instead of building new transmission corridors, reducing environmental impact and facilitating over 1 gigawatt of new renewable energy.
Ausgrid has started community consultation with drop-in sessions in Singleton and Muswellbrook, along with online discussions. The company is also carrying out early works in the Upper Hunter to finalise design plans for regulatory and environmental approvals.
“Ausgrid is committed to working with landholders and EnergyCo to finalise details of the design, with the aim of minimising impacts and maximising benefits for the local communities,” Ausgrid’s Group Executive Transmission Development and Growth, Kelly Wood said.
The project is expected to create around 175 jobs, including engineering and construction roles. It will also support NSW’s renewable energy and Net Zero targets by expanding the region’s capacity for wind and solar power generation.
