I was about to put another black mark by Davis' name but if he's only taking obviously politically motivated risks with eletrical energy consumers in the Pacific Northwest he probably deserves a pass.
Don't worry, Davis is working overtime to put black marks by his own name. He doesn't need help from anyone.
What is significant about WECC daily reports is that so often there are no serious problems, which is as it should be. However, the California ISO has been publicized as a source of reliability problems at least a couple times each month.
Remember the WECC report is what all the scheduling utlities in the Western U.S. & Canada read to see who things are going. California's power system is becoming widely known within the electric utility industry as disfunctional and un-trustworthy. That is significant.
