Point Henry smelter

The Point Henry aluminium smelter was located near Geelong, Victoria in the suburb of Moolap prior to its closure in 2014. The smelter had a production capacity of 185,000 tonnes of aluminium a year. It was operated by Alcoa World Alumina and Chemicals Australia, a joint venture between Alcoa (60%) and Alumina Limited (39.25%).Alumina was brought in by ship and unloaded at a dedicated pier, and approximately half of this finished aluminium was sold to the neighbouring Alcoa Australia Rolled Products plant, where aluminium was rolled into sheet for can manufacture. The remainder of the aluminium was despatched by road as ingots. Around 1000 people were employed at the Point Henry plant.

Construction of the smelter at Point Henry commenced in 1960 by the Cavalier Construction Company. Smelting commenced in 1962, with full production commencing on 4 April 1963. The initial electricity supply to the smelter was a 220 kV transmission lines from the Geelong Terminal Station direct to the smelter. When production started, the maximum power demand of the smelter was 39.76 Megawatts (MW). By June 1964 it was 68.38 MW, and by October 76.6 MW — more than the entire Geelong region's demand. In November the following year it was 78.88 MW, February 1967 79.84 MW, and 140 MW by 1969. On 20 March 1969 Alcoa's own brown coal-fired Anglesea Power Station was brought on line. With 150 MW capacity, the power station was connected to the smelter by around 30 kilometres of high-voltage transmission lines, and was used to augment the supply from the Victorian electrical grid.

The power demand of the smelter was 360 MW for a 185,000 tonne annual production capacity in 2014, of which approximately 40 per cent was met by the Anglesea power station. The Point Henry smelter, along with the smelter at Portland, used 18 to 25 per cent of Victoria's electricity production during the 2000s. In March 2010 it was announced that the operators of Loy Yang A power station (Loy Yang Power) had signed a contract with the smelter operators for the supply of electricity to power aluminium smelters at Portland and Point Henry until 2036, the existing power contracts expiring in 2014.
