ACT Second Electricity Supply Project
The project is an undertaking by TransGrid (the operator and manager of the NSW and ACT high voltage electricity transmission network) and Evoenergy, previously ActewAGL (ACT’s electricity distribution utility) and the ACT Government.
The aim of the ACT Second Electrical Supply project is to ensure a continued safe, reliable and secure electricity supply to the ACT.
The project has been carried out in two phases:
The first phase was completed in 2013 and included:
- the construction of the Williamsdale substation south of Canberra
- associated 330kV transmission line upgrades by TransGrid
- new 132kV transmission lines by Evoenergy.
The second phase, currently under development, comprises a new substation at Stockdill Drive, Holt and associated 330kV and 132kV transmission lines.
A draft Environmental Impact Statement (EIS) has been prepared to assess and document the potential environmental impacts of the construction and operation of the project.
