Key details

As coal-fired power stations close, existing transmission lines lack the capacity needed to transfer electricity from renewable energy zones (REZs) to consumers.

The Hunter Transmission Project involves building a new, 110-kilometre, overhead 500 kilovolt (kV) transmission line between Bayswater in the Upper Hunter and Olney in the Lower Hunter. It will connect the state’s existing 500 kV transmission lines, which will create a 500 kV ring of transmission infrastructure that will provide the backbone of the state’s new electricity grid for generations to come.

Importantly, it will unlock the electricity supply from the Central-West Orana and New England REZs.

Planning

Planning for the Hunter Transmission Project is well underway in line with the planning approval pathway for critical State significant infrastructure.
The environmental impact statement (EIS) for the Hunter Transmission Project was on public exhibition from 27 August to 24 September 2025.
To learn more about planning approvals and the EIS, see the page environmental impact statement for the Hunter Transmission Project, or view the digital EIS.
Under construction

If the Hunter Transmission Project is approved, construction is expected to start in 2027.
