When utilities were either municipally or locally owned the interconnects were solely for regional load balancing and backup capability. Now firms think nothing of building a plant where environmental restrictions are lax and shipping the electricity a thousand miles away.
Enron was only unique in that it got greedy and got caught. Selling electricity on the spot market has never made sense to me, so requiring a firm to buy at a fixed price for an extended period of time seems to go against current (US) trends. If there is a movement in the other direction I would like to hear about it. Policies not Politics ---- Daily Landscape
