> FWIW I'd think the pricing of the ToD plan versus the fixed rate plan has more to do with how the power company themselves has to buy power and model/hedge against demand at various parts of the day, rather than simply trying to make the costs even for the consumer.

I agree, my single point of evidence to support my theory is that the power company advertises the TOD plan by presenting an average customer with their breakdown of usage throughout a typical day, and then itemizes how it would look with flat-rate versus TOD. The resulting figure is within a few pennies. I figure that is not accidental, but I could be wrong and it is entirely coincidence.
