Branxton Substation

The new substation at Branxton will enable connections for proposed offshore generation and the Eastern Link project via the proposed converter station at Oxwell Mains. Underground cables will link these two projects to Branxton substation.

Below is a 3D flythrough model of our substation plans and we have also attached more information about our plans and would welcome any feedback you have using the email address provided below. 

SP Energy Networks submitted a planning application for the Branxton substation in December 2021. There have been a number of changes to the project since the application was submitted. Those changes are set out here.
