Something you may want to look into is you can qualify for a AG meter to be put in at the barn for Power. Here in Bama they Allowed me to put my well and pond stuff on a AG based Power meter. The benefits is that the AG KWH price is way cheaper than that of a residential meter KWH price. In my case it saves me several hundred annually. Also here there is no charge on the AG usage on the month that you do not need to use any Electrical.
For instance another little house on my property currently unoccupied used 342 Residential KWH at the cost of $66.45 last month.
MY last AG KWH bill was for 361 KWH at the cost of $31.51.
Just something that may be worth looking into as my low cost of usage quickly offset the initial cost. Not to mention you would be saying the money on the 175' of running wire.
Edit Georgia Power Does Offer
Oh yea the Key wording here to AG qualify was I was planning to raise and sell fish and that was what this power usage would go towards helping me do.
