Yass 330/132kV Substation Reconstruction

TransGrid's newest 330/132kV Substation was officially opened on 27th April, 2006 by the New South Wales Minister for Energy, The Hon Joe Tripodi MP.

The $45 million dollar project involved rebuilding what was Australia's first 330kV Substation when the original substation was commissioned in 1959. Yass Substation has now been re-built to increase its reliability and reinforce supply to the southern parts of New South Wales. It is the major interconnection point for supply from the Snowy generators to the Sydney and Canberra regions, and for transfer of power south from the main thermal generators in New South Wales and Queensland to south-western New South Wales, Victoria and South Australia.

Work on the complex project commenced in July 2003 and has created one of the largest Substations, and the most modern, on TransGrid's extensive network. The project has utilised innovative engineering solutions with the development of a new 330kV breaker-and-a-half switchyard and a new 132kV single bus switchyard.

At the opening, TransGrid's Chairman, Mr Philip Higginson said "This state of the art Substation is an integral component of TransGrid's commitment to ensuring the long-term continuity of supply to the New South Wales network".

Mr Kevin Murray, TransGrid's Managing Director said "TransGrid's guiding principle in the design and construction of the new Yass Substation was to ensure security of supply while being environmentally and socially responsible. Environmental considerations were at the forefront of TransGrid's planning and implementation of the new Substation".

He went on to say "The highest standards were applied both during construction, and will continue to be applied in the operation and maintenance of the Substation".

TransGrid's capital works program, amounting to $1.1 billion over the next few years across New South Wales, means that the people of New South Wales and the State's economy will continue to reap the benefits of a secure, safe and reliable high voltage grid.
