The power lines coming up the mountain are all above ground, the fiber optic coming up the mountain is all below ground. Rock must not be a big issue as fast as they got that fiber into the neighborhoods up here.

Be safe, stay dry, to all!

I don't have flooding issues either at my elevation. But power outages are 4-5 times per year either storms or ice/snow. The electrical co. here is Haywood...they are at odds with Duke Power at times, I believe they buy from them

...apparently Haywood is complaining to Duke about the outages. Got a letter from Haywood stating Duke is hoping to do more to prevent outages in my area.

Keep dry and good luck everyone!

We are with Mountain Electric Coop, but I wouldn't be surprised if MEC buys from Duke also.

True but restoring power lines after each major storm is expensive also.

How deep do the lines need to be buried? My cable/telephone lines are probably less than 9" underground...I think my underground power lines (I have 2) are buried significantly deeper.

Anyone know if/what the code standards are?

I have heard it varies.

24 inches for plain power lines.
If they are encased in nonmetallic material 18 inches.
If under concrete of 2 inches or more, it's another depth, I just can't remember what I heard.

I was installing a mailbox many years ago and cut the main phone line on our street. It would have been an expensive mistake, except that one of my neighbors worked for the phone company and he told me not to pay a cent for repairs because the line should have been 18 inches deep and it was only about 10. He must have been correct, they threatened to bill me about 800 dollars, but I never got a bill.

Turns there was a study done on “undergrounding” way back in 2003.

Interesting article about Duke Energy upgrades,it states that putting lines underground would cost about 10-15 times more than putting them overhead,initially.

Now we need to follow up on your previous statement about the cost of repair after each and every storm and accident. Surely there is a budget item/number the owners of the power grid have in place on a yearly basis to cover such items. I'm betting most of that number would go away with total underground systems.

That’s exactly what I was thinking,I’d like to know how much has been spent on it over the last several decades! While installing lines underground might cost a lot initially,it will safe money in the long run.
