'''Anglesea Power Station''' is located at [[Anglesea, Victoria|Anglesea]], in [[Victoria (Australia)|Victoria]], [[Australia]] within the [[floristics|floristically rich]] [[Anglesea Heath]] area. It is [[brown coal]] powered with one [[steam turbine]] with a capacity of 150[[Megawatt|MW]] of [[electricity]], supplying almost 40% of the electricity used by the nearby [[Point Henry smelter|Point Henry]] [[aluminium]] [[smelter]], operated by [[Alcoa of Australia]]. The power station was brought online on March 20 1969,<ref>''R. Arklay and I. Sayer'' - 'Geelong's Electric Supply' - September 1970</ref> and is supplied with coal by the adjacent [[Surface mining|open cut mine]], transported to the power station along a 3 kilometre long private road. Overburden is stripped and backfilled into the mined area by earthmoving contractors using conventional power shovels and trucks.

From 1955 test bores for coal were made at Anglesea by the Roche Brothers, who were then operating a mine at nearby [[Wensleydale, Victoria|Wensleydale]] where the coal reserves were dwindling. An extensive coal deposit was found two kilometres to the north of the Anglesea township, with mining commencing in 1959 to supply brown coal to industry and institutions in the Geelong area. The mining rights were taken over by [[WMC Resources|Western Mining Corporation]] (WMC) in 1961 to supply the power station planned by Alcoa of Australia. The Mines (Aluminum Agreement) Act of 1961 granted Alcoa a 50 year exclusive right to explore and mine over some 7,350 hectares of leasehold land in the region.<ref name="heritage">{{cite web |url=http://www.heritage.vic.gov.au/Publications/Typological-studies/Mining.aspx |page=Page 45 |title=Anglesea Brown Coal Mine |work=Coal Mining Heritage Study |author=Jack Vines |year=2008 |publisher=www.heritage.vic.gov.au |accessdate=2010-03-07 }}</ref> After further drilling investigation WMC relocated the mining operation to the east of the original mine, closer to the power station site and providing access to a larger coal reserve of 50 million tons. The total thickness of the coal seams is about 140 metres, with total economic mineable reserves estimated at 70 million tons in the upper seam, and a further 90 million tons in lower seams. In 1992 the overburden to coal ratio averaged around 2.5 to 1, with an average coal thickness of 27 metres.<ref name="heritage" />

As of 2005 approximately 35 million tonnes of coal had been mined, with about 1.1 million tonnes of brown coal mined annually to feed a boiler that consumes 144 tonnes of pulverised brown coal an hour. The coal at Anglesea has a high quality heat value when compared to other brown coals used to produce electricity in Victoria, but has a much higher level of sulphur of around 3%, resulting in high levels of [[sulfur dioxide]] (SO2) emissions.<ref>{{cite web |url=http://www.aluminalimited.com/case-studies/ |title=Victoria - Sulphur dioxide reduction at AWAC |publisher=www.aluminalimited.com |accessdate=2010-03-07 }}</ref> [[Carbon Monitoring for Action]] estimates this power station emits 1.21 million tonnes of [[greenhouse gases]] each year as a result of burning [[coal]].<ref>[http://carma.org/plant/detail/1560]. Carbon Monitoring for Action. Retrieved on 23 November 2008</ref> Anglesea draws its cooling water from six sub-[[artesian]] [[Water well|well bores]], supplemented with [[rainwater]].
