The Newport Power Station was a complex of power stations in the suburb of Newport, Melbourne, Victoria, Australia. Newport A, B, and C coal-fired plants operated at the site between 1919 and the 1980s, while the Newport D 500 MW gas-fired peak load plant has operated since 1981. Old Newport was claimed to be (in terms of the amount of plant) the largest power station in the southern hemisphere in 1953 with 42 boilers and 14 turbo-alternators producing 327 MW.Newport A, B, and CNewport 'A' was established as a coal-fired power station by the Victorian Railways in 1918 to supply energy for the electrification of the suburban rail system by the Victorian Railways, and to supply electricity to businesses that required 25 Hz power. Initially, there were six turbo-generators; four were 15 MW capacity and two were 12.5 MW. The speed was 1500 RPM and produced 25 Hz. Steam was supplied by 24 Babcock + Wilcox chain grate boilers at 250psi. The two smaller generators were replaced with a 30 MW Parsons and a 35 MW single cylinder Parsons alternator, numbered A2+A4. Steam was supplied by the four "M" boilers, which were pulverized coal-fired at 400psi. The plant also supplied bulk electricity to the Melbourne City Council Electric Supply Department, the Melbourne Electric Supply Company, and the State Electricity Commission of Victoria. It was transferred to the SECV in 1951, when the total capacity was 120 MW.
