Here we have a smelter in the far south of the country near a large Hydro
station. The two were built because of each other, as it were. I believe the
cost of electricity for them is around $US0.01 per unit although the actual
charge is a commercial secret. As well it may be when we pay 5 to 7 times as
much. (We do on average of course use rather less than the smelter and our
load curve is not quite as flat :-) ).
