Nepean to Menangle Feeder Upgrade

Following the rezoning of the area for new homes and local centres, we are proposing an upgrade an existing transmission line between Spring Farm and Menangle to meet forecast growth in electricity demand within the Greater Macarthur Growth Area and surrounding developments.

Overview

Following the rezoning of the area for new homes and local centres, Endeavour Energy is proposing an upgrade to 7.6 kilometres of the existing transmission line between Spring Farm and Menangle to address both current and future electricity demand in the Greater Macarthur Growth Area and surrounding developments. The proposed works involve:

  • replacement of up to 28 poles, removal of three poles, and construction of four poles in new locations. All works will be within 20 metres of new and existing poles.
  • replacement of existing overhead conductors and associated overhead line fittings.
  • existing substation at 156 Springs Road, Spring Farm to be connected to Power Pole Site 1 via trenching or underboring.

The need

Endeavour Energy is proposing to upgrade the existing feeder between Nepean Transmission Substation and Menangle Road, by replacing the current transmission line with a new 66kV feeder. This Project is part of the broader transmission supply strategy to meet increasing electricity demand in the Greater Macarthur Growth Area and surrounding supporting development. The transmission line will support increased supply, following rezoning of the area to establish new homes and local centres. The replacement of old poles, the construction of new poles and removal of redundant poles will comprise of the proposed works and are all required to support the new 66kV feeder.

The location

The proposed project will upgrade an existing feeder within its current alignment between Nepean Transmission Substation (156 Springs Road, Spring Farm) and Menangle Road, Menangle. This feeder runs through private landholdings including Elizabeth Macarthur Agricultural Institute (EMAI), Camden South.
