It states, The CISO issued a Transmission Emergency Notice for Path 26 at 18:22 based on north to south flows exceeding the path capability. The notice was terminated at 19:00."
It further stated, "From 0400-2200 the Path 26 is limited to 2,500 MW north to south and 3,000 MW south to north due to outage of the Los Banos-Midway #2 500-kV line."
Just for those who don't know Midway, is the electrical heart fom which life-blood main veins radiate from the Pacific Northwest Hydrosystem to California.
Right now there is a big debate occuring as to whether water should be spilled at dams (some claim it will help salmon, but little real science) or be used to generate electricity for part of this summer. Many in the PNW are becoming concerned that the snow pack is looking a little below normal for this time of year.
All of this should be interesting as the summer moves on. I still haven't heard that anyone (Arnord!) has cleaned house at the CAL-ISO. Until that happens, I wouldn't trust California to have reliable power.
