From your first link:
>Con Edison urged customers across New York City and Westchester to conserve energy as much as possible, in an effort to avoid further outages due to equipment failure.
I can't speak to California as I don't live there, but your original statement about rolling blackouts in New York was flat wrong.
The recent issue in New York during the heat wave was about aging infrastructure and equipment failures, not "green energy" or the closure of Indian Point.
That might change in the future, but your statement that New York experiences "rolling blackouts" is just false.
In fact, there have never been rolling blackouts in New York. Ever.
I wholeheartedly agree that nuclear should be part of the mix and that in the absence of viable grid energy storage, solar and wind energy can't provide base load[0] power generation.
