Menangle Park Energy Infrastructure Projects

To ensure an affordable, safe, and reliable electricity supply that supports future growth in the Greater Macarthur Growth Area, we are proposing to develop a new Menangle Park Zone Substation.

Project 1: Menangle Park Feeder

Overview

Endeavour Energy proposes to establish a new 66kV underground feeder, 85U, from TransGrid’s Macarthur Bulk Supply Point (BSP) to the proposed new permanent Menangle Park Zone Substation. This project does not require any ancillary facility during construction.

The Need

The proposal will strengthen energy reliability and service the growing residential and commercial developments in the Menangle Park region. It represents a key infrastructure upgrade to support the area’s future energy needs.

The Location

The feeder will be located on Fitzpatrick Road, within Lot 41 of Deposited Plan (DP) 1285744, Lot 2012 DP1234643, Lot 2008 DP1234643, Lot 32 DP1105615, Glenlee Road (road reserve), Lot 32 DP 1105615 and Lot 31 DP1105615. The site is within Menangle Park, approximately 49 kilometres southwest of Sydney CBD and about 1km east of the Nepean River.

Review of Environmental Factors

As the Authorised Network Operator and proponent, Endeavour Energy have assessed the project considering all environmental, technical, financial, and community impacts. Under the NSW Environmental Planning and Assessment Act 1979 (EP&A Act), Endeavour Energy is the determining authority. In accordance with Part 5 of the EP&A Act, a Review of Environmental Factors (REF) has been prepared, outlining:

  • Proposal description and justification (including benefits and objectives)
  • Overview of the relevant legislative framework
  • Consultation completed during the assessment phase
  • Consideration of alternatives
  • Environmental impact assessment and mitigation measures for construction and operation

Please see the REF for the proposal.

Community Correspondence

Stakeholder input and feedback are important parts of the environmental impact assessment process. Stakeholders and nearby landowners will be notified of construction works. Any planned electricity outages will be communicated to impacted customers and kept to a minimum.

We welcome your feedback on our plans by 11 November 2025.

If approved, a Notice of Determination, containing the development consent conditions and authorising the construction works, will be issued by Endeavour Energy.

Project 2: Approved Menangle Park Zone Substation Upgrade

Introduction

To ensure an affordable, safe, and reliable electricity supply that supports future growth in the Greater Macarthur Growth Area, Endeavour Energy is developing a new Menangle Park Zone Substation.

Overview

The works include:

  • Upgrading the existing mobile substation to a permanent facility, with two new transformers (and space for a third) and a permanent building for electrical and control equipment
  • Decommissioning and removing the current interim substation
  • Constructing supporting infrastructure, including a driveway, lighting, drainage, and connections for water and sewerage
  • Implementing security measures such as fencing, gates, signage, and an 11.5-metre pole for lightning protection
  • Installing safety systems, including fire management, emergency showers, earthing, and a battery backup system
  • Establishing a communication system with a 15-metre-tall antenna
  • Landscaping the site

The Need

The current mobile substation does not have the capacity to meet anticipated demand beyond 2027 due to expected growth in the region. The upgrade will secure an adequate long-term electricity supply for current and future residential and commercial customers in the Greater Macarthur Growth Area by providing a new diversified 33kV electricity supply. This supports urban renewal and new land releases in areas south of Campbelltown, such as Appin, North Appin, and Gilead, identified for substantial growth within the Greater Macarthur 2040 Interim Plan, which projects approximately 40,000 new homes by 2056.

The Location

The new zone substation is located on Fitzpatrick Road, Menangle Park.
