TransGrid powers on with major upgrade to Snowy Mountains switching station

New South Wales transmission network operator, Transgrid has completed the first stage of civil works as part of its major upgrade to the Murray switching station near Khancoban.

TransGrid’s southern region manager, Bob Rigg said the upgrade involves the installation of new high-voltage equipment at the switching station.

“Last week the project team completed civil works on a section of the substation which directly connects to the Murray 1 power station, which feeds hydro power into the national electricity grid,” Mr Rigg said.

“Replacement of electrical equipment will commence in January 2011,” he said.

The Murray switching station was built by the Snowy Mountains Hydro Electricity Authority four decades ago and the switching station is a critical connection point between the NSW and Victorian transmission networks, part of the national electricity grid.

“By upgrading the Murray switching station TransGrid is helping to ensure that customers continue to enjoy high standards of electricity reliability, both now and in the future,” Mr Rigg said.

TransGrid currently connects to a large amount of renewable energy sources in NSW, including over 4000 MW of hydro and wind generation.

The Murray switching station upgrade is expected to be completed in November 2011.
