Solar eclipse in August raising worries about Ontario's power grid
The President of the California Public Utilities Commission expressed some concern as well. California is not even close to the main shadow area.
How long will the eclipse last ?
Several months ago I read an interesting bit which revealed a 1/3 of CA power is imported due to growing sources of intermittent power gen within the state. Mostly from the NW and SW.....maybe the shadow will be impacting production zones typically relied upon by CA.
We'll be watching from Jackson Hole and it's estimated start/finish for about 2:45 mins, although totality is only 3 minutes or so.
If only there was a way to know precisely when this is going to happen so we can be prepared
Just like "nobody could have predicted the breech of the levees" this is just something we'll have to deal with if it happens
Doesnt' this happen every day, aka night, without armageddon happening?
The challenge to this particular situation is the solar power level at the time that will be lost and the short nature of the dip it will cause.
Fossil fuel plants are not known for their instantaneous ability to ramp up, but batteries can. There just aren't enough battery resources yet installed.
In San Diego, the eclipse is only rated at a level of 50%, but we have well over 500 MW of rooftop solar generation online. So within a 3 minute period, if it turns out to be a sunny day - and it probably will, I would guess we could lose at least 300 MW of generation and then have it "come back on" in 3 minutes.
So to keep the power system stable, it's really two event, the loss of that much generation, and the reappearance...It will be interesting, that's for sure....
So basically, it's like nighttime, but only for a couple minutes?
Been there, done that. Even in a smaller country. I guess John Q Public will just have to wait and see if the American and Canadian grid operators are as smart as the German ones.

Here is a map of where the totality will be:
