No matter WHAT the government takeover of the Nation's electric grid comes up with for rules, the power will flow as it always has, oblivious to what the FERC, DOE, or Kalifonia wants it to do.
Market forces do NOT change the laws of physics.....
Market force do dictate the position of the switch, open or closed. Without a price that can be paid, the switch stays open and the buyer to the East who purchased long term contracts gets the electrons. And the power plant is not turned on to supply power if the price is not going to be paid.
Well, market forces might have some impact on the guy and or system operating closures.
