I think it's interesting that the water used to power the plant flows into an existing pond, which happens to be the source of water for Whistler's man made snow. I have thought of one flaw in this system; If the ENTIRE mountain runs on one energy source, what happens if that source breaks down? I'm sure that Whistler's employees figured out that they need a reliable source, which is why this doesn't really worry me too much. But what would happen if the plant stopped working? Would the entire mountain be without power? That would really be a downer for skiers. Hopefully they have incorporated some kind of backup system in case this scenario plays out; possibly using their old system just for a day or two if its necessary.
I definitely want to make a trip to Whistler at some time in my life, and this is just another reason to patronize the resort.
