Overview
The Hunter Transmission Project (HTP) is declared both a priority transmission infrastructure project (PTIP) and a critical State significant infrastructure (CSSI) project. The Energy Corporation of NSW (EnergyCo) is the infrastructure planner for this essential initiative.
The project involves building a new overhead 500 kilovolt transmission line spanning around 110 kilometres between Bayswater in the Upper Hunter and Olney in the Lower Hunter. The HTP will also include building new switching stations in Bayswater and Olney, along with upgrades to the existing Bayswater and Eraring substations. This will add up to 5 gigawatts of extra electricity transfer capacity between Bayswater and Eraring.
Transgrid and EnergyCo have signed a commitment deed, officially confirming Transgrid as the preferred network operator for the HTP which will advance NSW’s clean energy transition.
EnergyCo will seek ministerial approval to appoint Transgrid as the network operator responsible for delivering, operating and maintaining the project. The commitment deed outlines a defined scope of work for Transgrid to support project planning and preparations for construction.
