Alstom Grid wins lucrative contracts worth more than $130 million

Alstom Grid has been awarded two contracts worth approximately €100 million ($AUD137.7 million) by TransGrid for three new high-voltage electrical substations in New South Wales.

The substations will be located at Wallerawang in the central-west area and Holroyd/Rookwood Road in the centre of Sydney. Both projects are scheduled to be delivered in 2013.

The Holroyd and Rookwood Road project, worth around €70 million ($AUD96.4 million), includes three gas-insulated substations, three air-insulated substations and three air-cored series reactors. It represents the first 330 kV gas-insulated substation contract awarded to Alstom Grid following a number of successful air-insulated substation projects delivered to TransGrid.

The scope of this project includes complete design, civil works including demolition, architectural aspects, landscaping and oil containment system, modular buildings, auxilliary transformers, protection and control system, AC and DC systems, communication system, installation, commissioning and testing work.

Driven by an increase in electricity demand in the region, mainly due to mining activity, the approximately €30 million ($AUD41.3 million) Wallerawang 132 kV air-insulated substation project involves a complete upgrade of the feeders between Orange and the Wallerawang substations.

“These substations will be critical pieces of our network and among the largest gas insulated projects we have undertaken,” TransGrid managing director, Peter McIntyre said.

Alstom Grid were awarded the contract after a successful tender process, backed by it’s solid track record in manufacturing and project management. TransGrid said Alstom Grid’s solution demonstrated innovation and will allow the transmitter to achieve a cost-effective solution for its customers.

“We appreciate TransGrid’s faith in us and we are confident that we can leverage our international manufacturing and local project management expertise to safely deliver these two major projects on time and to the satisfaction of TransGrid,” Alstom Grid president, Grégoire Poux-Guillaume said.

TransGrid owns and manages one of the largest electricity transmission networks in Australia and operates more than 90 substations and more than 12,600 km of transmission lines.
