You obviously have no clue, thinking outages are fixed as readily and don’t understand the costs. I’m an electrical distribution engineer for utility companies, you?
Congratulations. I'm a customer that pays your salary and you didn't answer the question as to how you came up with the 10-20 times cost to the user since I am a user of electricity that is delivered to my home via underground cables/wires/conduits and my end user price is the same as any other user in my town that gets their electricity delivered via overhead wires.
I don't give a fat rat's ass about the costs for repair of an underground wire vs overhead wire, Mr. Engynnneer.
The utility company has factored the costs into their sale price, and have decided that they can deliver my underground electricity at a reasonable cost {or otherwise, there would be wires hanging all over my neighborhood, and there are none}.
I would not want to pay 10-20 more for underground delivered electricity, and no rational electrical distribution engineer would posit that as a reasonable premise in an argument, Mr. eegator.
With that kind of logic, stay in the engineering trade, because you can't stand up in a rational discussion.
