An aluminium smelter runs 24/7. It's a continuous process of electrolysis that also produces the heat required to keep the contents molten. If the power goes down for even a very short period of time (I last had to deal with this a long time ago, but I think it is about 15 -30 minutes), the contents solidify, there is not enough electrical resistance to produce the heat to bring it back to a liquid, and the vat has to be scrapped.
Basically, if you power down, you pretty much have to scrap the smelter and start from scratch.
When I was with Eskom, you have no idea how seriously keeping power to the Richards Bay smelter was taken.
