SYDNEY, NSW – The New South Wales Government has granted planning approval for the Hunter Transmission Project, a critical infrastructure development poised to unlock 5 gigawatts (GW) of renewable energy capacity and bolster grid stability across the state. The decision, announced on 30 July 2026, marks a significant step towards integrating clean energy from the Central-West Orana and New England Renewable Energy Zones (REZs) into the National Electricity Market (NEM), aiming to deliver more affordable and reliable power to Australian homes and businesses.
The project, a new 110-kilometre, 500-kilovolt (kV) transmission line, is designed to bridge a crucial network gap as NSW’s ageing coal-fired power stations progressively retire. Construction is scheduled to commence in late 2026, with the project expected to be fully operational by late 2029.
Bolstering Energy Security and Lowering Costs
NSW Minister for Climate Change and Energy, Penny Sharpe, emphasised the project’s vital role in securing the state’s future energy requirements. “The Hunter Transmission Project is one of the most important energy projects in NSW because it will help keep the lights on as ageing coal-fired power stations retire,” Ms Sharpe stated. The new line will connect the abundant renewable energy generated in the Central-West Orana and New England REZs directly to major demand centres in NSW, including Sydney, Newcastle, and Wollongong.
This enhanced transmission capacity is expected to facilitate the flow of cheaper, cleaner electricity, contributing to lower retail electricity prices for consumers. For households and businesses looking to manage their energy costs, understanding their options from various providers remains crucial, even with grid improvements.

“This project is the missing link between the renewable energy being built in Central-West Orana and New England and the millions of homes, businesses, schools and hospitals that rely on affordable and reliable electricity every day.” — NSW Minister for Climate Change and Energy, Penny Sharpe.
Economic Benefits and Environmental Safeguards
Beyond its energy implications, the Hunter Transmission Project is projected to create substantial economic opportunities. The development is expected to generate approximately 830 construction jobs, including over 160 positions directly within the Hunter region, and support around 1,500 direct and indirect jobs state-wide.
Minister for Planning and Public Spaces, Paul Scully, confirmed that the project approval includes stringent conditions addressing biodiversity, Aboriginal cultural heritage, social impacts, and local business participation. Following extensive community consultation, approximately 90 per cent of the approved transmission route will now traverse mining, energy, and government-owned land. This revised alignment significantly reduces the number of directly impacted private properties from around 70 to fewer than 20. Furthermore, the design changes minimise vegetation clearing and successfully avoid nearly all known breeding ponds of the threatened Littlejohn’s Tree Frog.
Integrating Renewables for a Stable Grid
The Hunter Transmission Project forms a key component of the NSW Electricity Infrastructure Roadmap and is supported by the Australian Government’s Rewiring the Nation program. It is critical for maintaining grid stability as NSW transitions away from a coal-dominated energy mix. The addition of 5 GW of transfer capacity will allow for greater integration of variable renewable energy sources, such as wind and solar, ensuring a more resilient and secure electricity supply.
As major transmission projects like this progress, the role of distributed energy resources, including home batteries, becomes increasingly important for localised grid support and household energy independence.
