Proposed Feeder 940 Foundation Refurbishment
The project involves the refurbishment of the foundations of 25 existing transmission towers located along a section of Feeder 940, located between Lawson at the eastern end and Marrangaroo (west of Lithgow) at the western end. The feeder traverses the Blue Mountains and travels through the Blue Mountains and Lithgow local government areas. The refurbishment works involve a staged process comprising:
- vegetation removal (where required) and excavation of each tower foundation to expose each structural element
- cleaning of the foundation
- visual (condition) inspection and determination of the appropriate refurbishment works
- undertaking the necessary refurbishment works
- backfilling and rehabilitation work
The project would also include upgrades of existing access tracks to enable access each of the transmission towers.
The foundations of some towers along Feeder 940 are a “grillage” design, which uses steel bars and plates attached to the leg that are directly buried in the ground. Because the steel tower legs, bars and plates are in contact with soil, the grillage footings are at risk of rust/corrosion damage.
Endeavour Energy intends to refurbish the tower footings to ensure that the footings and the transmission towers they support remain safe and stable, contributing to the reliability of your power supply.
As shown in the map below, the transmission feeder is located between Lawson at the eastern end and Marrangaroo (west of Lithgow) at the western end. The feeder traverses the Blue Mountains and travels through the Blue Mountains and Lithgow local government areas.
Further details of the location are provided in the Review of Environmental Factors (REF) below.
Review of Environmental Factors
As the Authorised Network Operator and proponent for this proposal, Endeavour Energy have undertaken an assessment of the project in consideration of all environmental, technical, financial and community impacts. Under the NSW Environmental Planning and Assessment Act 1979 (EP&A Act), Endeavor Energy is the determining authority of the proposal.
In accordance with Part 5 of the Environmental Planning & Assessment Act , Endeavour Energy has prepared the REF which outlines:
- the proposal description and justification (including benefits and objectives)
- an overview of the relevant legislative framework
- consultation completed during the assessment phase
- consideration of alternatives and
- the environmental impact assessment and mitigation measures to be applied during construction and operation of the proposal.
When approved, a Notice of Determination containing development consent conditions and authorising the construction works will be issued by Endeavour Energy for the development.
Stakeholders and landowners located nearby to the proposal will be notified of construction works. In the event any electricity supply outages are required to facilitate the safe construction of the proposal, any impacted landowners will be notified in advance.
Any required planned electricity outages will be kept to a minimum and be as short as possible to safely facilitate the development.
