Newport Power Station
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 C==
Newport '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 businesses that required 25 Hz power. Initially, there were 6 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 250 psi. The 2 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 4 "M" boilers, which were pulverized coal-fired at 400 psi. 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. The plant was transferred to the SECV in 1951, when the total capacity was 120 MW.
The SECV opened their Newport 'B' station in 1923 to supply electricity to Melbourne until the Yallourn power station entered service. Initially there were 2 Parsons 15 MW generators. Speed 3000 RPM and 50 Hz. Later No3 was installed of 30 MW capacity and No8, a Stahl turbine with a capacity of 22 MW. Steam was supplied by 10 B+W chain grate boilers at 250 psi. Total B station capacity was 82 MW.
In 1947 the Newport 'C' station of 120 MW capacity was opened by the SECV after wartime delays. There were 4 Parsons 30 MW turbo generators numbered 4,5,6+7. Steam was supplied by 8 "D" type ICAL chain grate boilers, each produced 175000lb/hr at 620 psi and 840 °F. The power station boilers were originally fuelled by imported New South Wales black coal, but were converted to burn brown coal briquettes in the 1950s. Use of the plants declined with the opening of newer power stations in Latrobe Valley, being used for peak loads in later years. These were the last chain grate boilers used in Victoria and were still in service early 1981.〔my own recollections〕
