For those who haven't seen, distribution management is actually pretty cool. Balancing power on the grid is a real-time task and it's not as trivial as you might think. There are three phases of AC, different voltages, and different frequencies (think slightly-different so that they drift with respect to each other...). Generators are potentially out of phase with respect to each other and ramping up/down throughout the day. Loads ramp up/down too, noticeably shift in response to things like TV programs coming on, and change their inductive/resistive profile. This is all managed in super-nifty control centers:

These guys already take TV shows and wind forecasts into account during grid planning but a CME is going to throw them for a loop? Doesn't seem likely.
