First of all, I would point out that I have toured the IESO. I have worked with them a lot. They're wonderful people, and the control centre is really worth seeing. In the Ontario situation, the tie-lines to the U.S. are used heavily. One of the reasons that the comment has been made that we're selling power at cents on the dollar is because in the U.S. wind is subsidized, and the night price of wind often drops to -$15 per megawatt hour so you're paying people to take the power. The politicians in Ontario have blocked that. That's a problem.
We would be far better off to trade with Manitoba and with Quebec than to trade with someone who has subsidies applied that are allowing them to make money at -$15. I would argue that the tie-lines are doing a wonderful job now of improving security, because while you get many fewer outages than Quebec does, or than an isolated utility would, you do suffer when something really bad happens and the whole system goes down. I would say that overall, the interties do a great job for Ontario.
