[time-nuts] 60 Hz power glitch, US West coast (Silicon Valley)

[Bill Hawkins]

Looking at PG&E's sources of energy, 60% comes from easily controllable
sources like gas, nuclear, and hydro.

40% comes from wind, solar, and other that are not so easily regulated.

Steam generators can't me moved thermally as fast as winds drop or
clouds develop.

Then there is the load side, with who knows what equipment making large
swings.

It would be interesting to hear from other parts of the country, but
cycle-watching hasn't caught the interest of this group yet.

I think this is the biggest dip I've seen, down below 59.8 Hz.
That's averaged over 10 seconds.

This one got below 59.9 Hz.

I guess I should write some code to scan the archives.  I wonder how
many similar glitches I've missed.

The last 50 days days:

Peak-peak offset is 15 seconds.
