The redevelopment of Beaconsfield West Substation is a major investment to secure the power supply of Sydney’s inner metropolitan area and central business district for the future.
This project is just one part of a five year, $2.6 billion plan by TransGrid to build new or upgrade existing substations and transmission lines across NSW.
What is the project?
The Beaconsfield West Substation is located on Burrows Road in Alexandria. The substation is a vital part of our existing transmission network in securing future power supply into Sydney’s CBD.
The Beaconsfield West Substation was commissioned in 1979 as the first major electricity supply to Sydney’s inner metropolitan area. We have purchased the two sites next to the existing substation on Burrows Road. For the upgrade, we propose to:
The Beaconsfield West Redevelopment Project involves:
- Establishing two buildings to house new 132kV gas insulated switchgear (GIS);
- Installing a third 330/132kV transformer (on southern site);
- Installing two 132kV 160MVAr capacitor banks (on northern site); and
- Establishing a gantry across the site for cable connections.
The redevelopment including a new transformer will increase the substation’s capacity by about 50%.
Where are we up to?
Construction is progressing on the Beaconsfield West Redevelopment Project. TransGrid's contractor UGL is undertaking the work in two phases over four years.
Phase 1 - Southern Site
Construction of the southern building is complete and the GIS switchgear has been installed. A new 330/132 kV transformer has been installed and a new overhead gantry has been erected. The gantry carries the gas-insulated conductors that connect the southern and northern sites. This phase of the project is due to be commissioned by second quarter of 2012.
Phase 2 - Northern Site
Construction of the northern building has commenced with GIS switchgear to be installed from April 2012. The completion date for this phase of the project is scheduled late 2012.
