Paul, as was already mentioned, the power companies have certain criteria to determine cost, if any, that they'll charge to get service to you.
For instance, in PA, if you go with overhead lines, they required a clearing of 32' wide. In PA, we do have icing problems. Going underground with a trench only required 16' of clearance.
Also, the power company had different cost schemes for actually living full time on your property vs. using it as a weekend getaway.
When and if you talk to a power company representative, I would be vague about what you're plans actually are so they can't pigeon hole you into something. This way, they'll have to outline the different options.
