There is now a separate article on the Portland aluminium smelter. Could remove some of the detail on this page. Qwerty310 23:47, 25 August 2007 (UTC)
[edit] Geothermal
We seem to have a million different figures for it, that differ considerably. Here they are for interests sake:
- Wannon Water
http://www.wannonwater.com.au/media_releases/2006_media/20060118.html
The Henty Park bore was constructed in 1982 for the purpose of extracting 2,400 megalitres of geothermal heated water from the Dilwyn aquifer 1.3 kilometres below the city of Portland.
- DEPARTMENT OF PRIMARY INDUSTRIES
Operating since 1983, Portland draws its water supplies from four bores drilled 1400 metres below the natural surface. • The water is brought to the surface at a temperature of 58 degrees celsuis at a rate of 56 litres per second.

Portland in Victoria has the only geothermal space heating facility in Australia providing an estimated 3.6MW for space heating to local residents and for heating the municipal pool.
- Murdoch University / Research Institute for Sustainable Energy
http://www.rise.org.au/info/Tech/geo/index.html
Portland in Victoria has sued hot water (58°C) extracted from a bore (1400m deep) at a rate of 90L/s, to heat more than 19,000 square metres of buildings for more than 15 years, and also heat 2000m3 of swimming pool. It is the only spaceheating project in Australia that uses a geothermal resource, as opposed to heap pumps. The total capacity of the Portland facility, operated by the Glenelg Shire is 10.4 MWt (Burns, K.L., Weber, C., Perry, J. and H. J Harrington, 2000).
All appear to be reliable, so make of it what you will... Wongm 03:58, 28 August 2007 (UTC)
Just to add another confligting site....
- Murdoch University

Portland in Victoria uses hot water (58 degrees C) extracted from a bore (1400m deep) at a rate of 65L/s to heat more than 19,000 square metres of buildings for more than 15 years.
