New England REZ
Snap Shot
The New England Renewable Energy Zone is set to be the largest of NSW’s Renewable Energy Zones by capacity and scale. Located in northern NSW around Armidale, it will connect new wind, solar, storage and pumped-hydro generation to the grid, helping replace retiring coal-fired power as a cornerstone of the NSW Electricity Infrastructure Roadmap.
Turnbull Engineering is working directly with the client, EnergyCo, across two successive contracts providing Site Management Services and the Principal Contractor role for the project’s early works.

Project Overview
EnergyCo, as infrastructure planner for the state’s renewable energy zones, is developing the New England REZ network - new high-voltage transmission lines, substations and energy hubs to carry renewable power to homes and businesses. The network will connect generation across the New England region to the existing grid, with the transmission corridor refined to around one kilometre wide running south to Bayswater Power Station.
As NSW’s largest REZ, the project is expected to unlock up to 6 gigawatts of new renewable generation and storage and involves around 575 kilometres of new transmission line. EnergyCo is running a competitive procurement to appoint a network operator to design, build, finance, operate and maintain the network, with a preferred operator expected in 2027 and financial close anticipated in 2028.
Turnbull’s Involvement
Turnbull’s first engagement covered Site Management Services for the New England REZ, with a scope that also included the Principal Contractor role. This contract was completed in 2025.

Project Highlights
-
Principal Contractor on NSW’s largest REZ
Turnbull is engaged directly by EnergyCo, the NSW Government body planning and delivering the state’s renewable energy zones, not as a subcontractor to a delivery consortium.
-
Designing around live traffic
Across both contracts Turnbull has held the Principal Contractor role, carrying on-the-ground responsibility for the safety and compliance of EnergyCo’s early site works ahead of the Network Operator’s engagement.
-
NSW’s largest REZ
The New England REZ is the largest of the state’s planned renewable energy zones, central to replacing retiring coal-fired generation under the NSW Electricity Infrastructure Roadmap.
-
Backing the energy transition
Up to 6 gigawatts of new renewable generation and storage, carried by around 575 kilometres of new transmission across the New England region.
