Lithgow power station was an Australian power station built in 1928 to supply power to the New South Wales Government Railways, the small arms factory, Hoskins mine and Lithgow council. The initial plant was two 2.5MW BTH/English Electric turbo alternators that were no longer needed at Ultimo power station. A third 2.5MW turbo alternator from Zarra Street, Newcastle was added in 1931. A fourth 2.5MWBTH machine was installed in 1936 (ex Zarra St). In 1943 a 2.5MW Willans & Robinson generator from Zarra St became No5 at Lithgow. Steam was supplied from four 160,000 lb/Hr boilers at 200PSI and a temp of 450degF. Coal came from the nearby State Mine. Due to a severe lack of water, these turbines only exhausted into individual jet condensers.
