Taking the Long Way

Posted in Transmission by Cheryl Morgan on the August 6th, 2008

Much traveling going on here again, but in the meantime please check out this interesting post from Michael Giberson at Knowledge Problem which explains how cunning traders were using inventive schedules to artificially create congestion between PJM and NYISO. Estimates of the amount of money milked from the system range as high as $290 million. Ouch.
