City wide outage

There’s a cost to everything and underground lines cost a minimum of 5 times (per mile or km) more than overhead. Yes, reliability of underground lines is higher but your monthly bills will be higher for that additional reliability.
Yeah I totally get that. And if you only have outages or storm events that pull down lines and brake poles every 10 years it may not be worth it. But the price of crews working 24 hours in hazardous condition sawing trees and limbs out of down the power lines Mass it outages etc etc it's a pay me now or pay me later deal, and to never have to worry about that again driving over a down power line or having one in your front yard to me makes it totally worth it.
