Like I said didn't cost me anything except an extra 200 amp panel. I guess it does cost me like 7 bucks a month for the separate meter but it's charged at regular residential rates. I'm guessing it'll take a really long time to pay back that transformer and the directional drilling.
Yeah, I'd totally go bigger if the cost were the same. I cringe at the thought of what Duke would charge me to upgrade to 400a at the shop. Right now it's my house, shop and 1 neighbor's house on the transformer so I'm sure they've have to upsize it and I'd have to pay for it.
The drilling didn't cost them much since they're probably paying for that crew whether they're working or not. But transformer aren't cheap.
Did they actually drill it? At my old house when I lost a neutral on my buried service, they sent a crew out to run a new line and they dug a series of potholes and used it pneumatic ram hammer thing to pound a path from hole to hole and then just puled the new line through. First time I'd seen it. A crew of 4 guys knocked it out in like 3 hours for about a 150' run. Even a little drill would have done far more damage to my yard.
