New South Wales Government-owned Macquarie Generation is to approximately double the size of the solar array alongside its Liddell power station in the Hunter Valley.

A new 18,000 square-metre field of mirrors with generating capacity of 9 megawatts – enough to power 1000 homes – will be used to generate steam, acting as a ”solar boiler” and saving fuel at the coal-fired power station.

The enlarged array will be the largest solar thermal power project in the southern hemisphere, although it is tiny by world standards. China, Morooco and Sudan have all announced plans for 2,000 megawatt solar thermal projects while the United States has announced half a dozen projects between 500 and 1,000 megawatts.
