CAISO declares second stage two emergency due to a new fire affecting
the Northern California intertie power lines with Oregon.

  Continued heat exacerbated by a fire that erupted near the Oregon
  border led to the Stage Two declaration. The fire was reportedly
  caused when a transmission line that is part of the crucial California
  Oregon Intertie (COI) sagged into a tree, igniting the fire. Power
  deliveries headed into California on the path of lines that make up
  the COI have been cut by several hundred megawatts. Additionally, a
  total of 3,964 megawatts of power plant units are off line today due
  to mechanical failure or planned maintenance that could not be postponed.
