Default Almost OT: "Florida Flicker and Flash'?

Years ago, my friends from Florida characterized their electric utility as:
"Florida Flicker and Flash".
I had never thought of it before, but, since there's water on 3 sides, they don't have any way to connect to power sources other than from the north if their generation system has a hiccup.
Is that still true? Have they gone underground with high voltage supplies?
Or does everyone south of Tampa still need a generator?

Just to make things worse, I think central Florida has the highest likelihood of Lightning strikes in the USA.
This just adds to the "Flicker", I suppose. We sure did sell a lot of power and signal line protection equipment down there years ago.
Google:
isokeraunic map usa
if you want to see how the rest of the country ranks.

We just got an email from a southern tip (east side) friend who is going to sit there and ride it out. He talks about the amount of gasoline stored, food and water, etc.. I guess he has had enough and will be relocating asap after Irma.

The news also made some comments about gas leaking,,, I think they were referring to natural gas. So it sounds like even that is not as reliable as some folks were hoping.

Would guess gas leaks are when houses are destroyed, pipes by/inside house might break.

Long cross country lines have losses, they like to distribute power plants thru out large areas. Just googal location of "Turkey Point and St Lucie" as an example

"Florida Flicker and Flash". ......... I remember walking along rt A1A at night ~ 400 ft from ocean and all the local street pole insulators were crackling like mad. Salt spray builds up on the cross country high voltage insulators too,they have to wash it off. Read for cross country lines they have a crane and a PULSED water stream, no continuous path to ground so they don't have to shut off the line

I see a lot of overhead wires in Florida like rest of the country when I was there years ago. Under ground hi-voltage line attract water thru the plastic insulation googal water treeing , then you have to spend $$$ and time digging them up to fix..

I have friend that works in Prudhoe bay AK and they wash the power pole insulators from a helicopter to keep them from shorting out.

I read about the pulse water system in a engineering magazine as a new product ~ 10 years ago. Maybe they couldn't find anyone that would dare to use it.??? I wouldn't want to use it!!

You can fly a helicopter right up to an energized wire and a guy can step out and work on the wire. The helicopter and the man both feel nothing.

I meant with the crane. Read a little more about it seems the crane has a 16 foot insulated boom. Think water was distilled, ~ 18 megohm water, so won't ground the bucket. Was told by utility maintenance guy the +- 750 kV DC lines here use 15 ft length insulators.

Just googaled "water cleaning high voltage insulators" . Seems they also can use lasers and also air blast media at them to clean them (corn cobs) , interesting.

Looks like they clean the whole insulator in one pass, start at energized end.
