The substations — to be located at Wallerawang in the Central West area and Holroyd/Rookwood Road in the centre of Sydney — are scheduled to be delivered in 2013.
The Holroyd and Rookwood Road project, worth around €70m, includes three gas-insulated substations, three air-insulated substations and three air-cored series reactors.
The scope of this project incorporates complete design, civil works including demolition, architectural aspects, a landscaping and oil containment system, modular buildings, auxiliary transformers, a protection and control system, AC and DC systems, a communication system, installation, commissioning and testing work.
Driven by an increase in electricity demand in the region, mainly owing to mining activity, the Wallerawang 132kV air-insulated substation project — worth approximately €30m — involves a complete upgrade of the feeders between Orange and the Wallerawang substations.
