So the question is, do you build infrastucture to deal with storms, or do you continually rebuild it. Which is more affordable and less hectic?
Corvallis has to worry about mega-earthquakes and resultant tsunamis. Not as frequent, but will certainly be worse.
Underground power should be standard by now. Bitching about the cost is saving pennies now in lieu of dollars in the future. You all make fun of taxes in CA but I can't recall seeing above ground power lines anywhere.
Anaheim,California added a 4% surcharge to gradually bury theirs, at a cost of $3 million/mile. Oh...the project to bury those lines, will take an estimated 50 years to complete.So does one go with that plan and hope that in 50 years when it's complete, it won't be outdated?
BTW- there is roughly 210,000 miles of overhead electric lines in CA
1) The cost to convert existing to ug would be astronomical. Ug cable is up to 10x the price of overhead wire. It is 2 totally different cables. Not to mention if it is getting put in conduit, which is expensive.
2)It is much easier/faster/economical to set a new pole or hang new wire as compared to having to dig up someones yard to fix a faulted ug cable.We just spent 12 hours chasing faulted ug cable through a residential area, digging up 4 different yards repairing one fault and it being faulted in another spot and so on.Total of 4 faults in the 20 year old ug wire. We have to pay for the landscapers to repair everything, deal with irate customers because their yard is tore up and if their yard has a fence we typically either tear part of it down or take it apart to get equipment in there so then that results in having to put new fence up and so on. On several occasions we had to destroy part of a fence. We offered to put up a new section. The customer would not accept that because their fence was old and weathered, therefore the new section wouldn't match. We had to buy an entire fence for their property.
3) Installing it can be extremely time consuming. If it is being put in continuous conduit that will need bored in. We just had a boring company spend 2 weeks on1 run where in good terrain it would take 2 days. The area was nothing but underground boulders. The price to bore through rocks can be about 5x more as regular terrain.
Those are just a handful of examples and reasons as to why it's not completely being buried. I didn't even mention the logistics of all the switches and transformers. Overhead lines have more than the line and a transformer. There are switches, reclosers, sectionalizers and other equipment that comes into play. Those lines can be tied together at certain points, if need be, to prevent outages if maintenance is being done or if a piece of equipment fails.
There is a lot more to the way electric is delivered than meets the eye.
Don't get me wrong, NEW housing developments typically are going to be ug because it is generally obstruction free and much quicker and easier to do.
