I live in PA where a small tornado came through four counties leaving 400k
people without power. It has brought down trees and power lines; imagine that!
Tonight the "news" showed pix of an outside power co's that sent crews to help
the local utility (PECO) with restoration. It was named Pike and I believe they
said it was from N Carolina. I expected to see Nooner or Jake but no luck.
It's not surprising they had to bring in outside help because PECO has been
getting rid of the more experienced people and either not replacing them or
with outside contractors. But not to editorialize but things come around in a
circle.
The Philly Inquirer had a pix of a lineman removing the ground clamps from a
repair.
Funny but when I was writing this I heard some local cops tell the comm center
that the local phone co (Verizon) had a generator that was back feeding to a
local convenience store and he wanted PECO notified so nobody got hurt. The
dispatcher was quizzing him and his reply was "The situation was explained to
me by the Fire Co. and I'm not an electrician and I don't pretend to be. Just
tell PECO they have to check it out and to use caution so nobody gets hurt".

Queens, NY, some 100,000 or more people without power for a week.
During 100 degree temps at one point. No one in the Con Ed is really
sure why the power is out. Lot of miserable people, I'm sure.

Oh they know why the power is out alright. They may not know where the
problem is but they know what happened.
You see it's all of the people who ran home and turned on their a/c
equipment without thinking that everyone else in the borough was doing
the same thing. The power infrastructure was unable to handle the
load and many points along the line just melted.

Sorry for the late reply.... it's been hot in Indiana too... and the
systems don't like 110% load too much.
Much like the systems you guys install, HV systems are 'usually'
protected against melt down... unless some moron decides to override the
safeties and take their chances.
The down-and-dirty is we don't have enough generation, and we don't have
transmission to handle high peaks anymore. That went out the window
more than 5 years ago. While systems used to be designed for 20% over
rated capacity... it just doesn't happen these days.
I saw the ISO reports on NY. No lines 'melted'... as far as anyone can
tell. Subs tripped... then reclosed... then tripped again until they
gave up.
Even if the fault was a under-voltage condition, utilities are required
(by due-diligence) to check the entire secondary system before
re-energizing. This takes some time... as you might imagine.
Ron is right... utilities know very well what their load profiles look
like. They go to great lengths to ask customers to 'stagger' their
loading of the system. People don't listen... and then they're out of juice.
The 'system' will protect itself... above all other factors.
We don't have enough capacity anymore, and people are going to have to
learn to adjust.
