The delivery of the components on five low-loaders from the Port of Newcastle is the second phase in a $72 million technology upgrade of Liddell.
Installation of the advanced low-pressure turbines will coincide with Liddell Unit 2's transition to a digital Distributed Control System to manage operations and performance.
Liddell's Unit 3 has been operating with the computer-based Digital Control System since December 2002.
By 2005, all four of Liddell's 500-Megawatt generating units are scheduled to be operating with the new technology, which is expected to deliver carbon dioxide emission reductions of up to 300,000 tonnes per annum by 2008.
The new technology investment is major component of Macquarie Generation's greenhouse gas reduction strategy, which commenced in 1999 with the launch of Australia's first biomass co-firing program at Liddell.
