Calderwood mobile substation
We are building a zone substation within the Calderwood Urban Development Precinct, to help supply safe and reliable energy to the people of the Shellharbour area.
Overview
The proposed Calderwood zone substation (ZS) site is located at the eastern edge of the Calderwood Urban Development release precinct on Calderwood Road and will be developed over two stages. The first stage will be a mobile trailer-mounted transformer facility. When electricity load demand dictates, a permanent built transformer and switch room facility will be built.
The Calderwood ZS is planned to provide a dedicated electricity supply to the Calderwood Urban development area, parts of Albion Park and future development in Marshall Mount and Yallah. The substation will be operated and maintained by Endeavour Energy.
The key features of the project involve:
- Installation of a trailer mounted 22MVA 33kV/11kVtransformer unit
- Installation of a trailer mounted control room to house a 11kV switchboard, protection and control equipment
- Construction of security fencing to protect the electrical equipment and ancillary works
- Benching/levelling of the substation site
- Overhead and underground electricity connections to the exiting electricity network
The need
The Calderwood ZS will provide safe and reliable electricity to the Calderwood Urban Development land release project, which will provide up to 7,700 new dwellings, 50ha of commercial/mixed land use and other infrastructure development over the next 20plus years. The area to be serviced by the ZS, covers developments in the local government areas of Shellharbour City Council and Wollongong City Council.
