A new transmission cable project from Potts Hill to Alexandria to provide a safe, reliable and affordable electricity supply for Sydney’s CBD and surrounding areas.
Why do we need Powering Sydney's Future?
Sydney’s population and economy are continuing to grow and with it our community’s demand for safe, reliable and affordable electricity. Did you know that parts of the electricity network are over 50 years old? These parts of the network are approaching the end of their serviceable life. Due to their current condition, some of the high voltage cables no longer transport as much electricity as they were originally designed to. That is why we are planning to build an essential 20km underground cable to meet the future electricity needs of Sydney’s Central Business District (CBD) and surrounding areas.
What is Powering Sydney’s Future?
Powering Sydney’s Future is TransGrid’s project name for a new transmission cable from Potts Hill to Alexandria. Powering Sydney’s Future involves:
- Installing a 20km 330kV underground cable from TransGrid’s Rookwood Road Substation at Potts Hill to the Beaconsfield West Substation at Alexandria
- Upgrading substations at Rookwood Road, Beaconsfield West and Sydney South
- To avoid future disruption we are proposing to install additional infrastructure to allow for a second cable at a later stage.
