That comment about wholesale prices is not actually quite true here in the northwest where avoiding BPA actually sometimes results in cheaper power (ie grant, douglas and chelan counties whoes PUDs own their own dams and are obligated to service their customer and as non-profits actually sell to retail users at near the wholesale grid rates since they have nearly zero cost).
Because pacificorp is a private utility they are actually only able to get the leftovers of the hydro from the northwest, BPA must sell to public utilities first (even if it is LA) so there are effectively two prices here in the northwest for wholesale and that is why pacificorp, portland general and puget sound energy all have far far higher rates than the public utilities, even the public utilities with no generation of their own. I was pretty surprised about facebook's choice as well, almost an identical climate can be found along the columbia river in the same places that the very cheapest power is located. They must have some other factors than just weather significantly contribute to the costs to justify not going for the cheapest power.
