Sydney North Secondary Systems Replacement Project

The Sydney North Substation located in Dural off Old North Road was commissioned in 1963 and is one of a number of key substations located in the Sydney Metropolitan area.

  • Why is the project needed?

    ​The substation is a bulk supply point for both Ausgrid and Endeavour Energy who supply electricity to homes and businesses in the area. The secondary systems that help to manage the flow of electricity within the substation have been identified as coming to the end of their serviceable life and require replacement.

    The replacement of the secondary systems will ensure a reliable supply of electricity to the Sydney Metropolitan Area into the future; and ensure that the substation is maintained to a safe and serviceable condition. This project will also meet compliance requirements with the National Electricity Rules and the Australian Energy Market Operator's standard for Power Systems Data Communications.

  • What are the works that will take place?

    ​The work will include a range of small scale construction activities including removal of old equipment, digging trenches, laying foundations and installing new equipment including new monitoring systems.

    A Review of Environmental Factors has been completed for this project and all work has been designed so that it does not compromise the ecological diversity of the area nor have significant detrimental impacts on the surrounding area.

  • When will the project start and finish?

    Civil construction work is expected to occur intermittently between April 2015 and March 2016, and again between September 2017 and October 2018. This project is expected to be completed in 2018.

    All work will take place within the confines of the substation and working hours will be in accordance with the Interim Construction Noise Guidelines typically between 7am and 6pm Monday to Friday and 8am – 1pm Saturday.
