I had the Power Company send their surveyor/estimator to my land about 18 months ago. It cost just under $30,000 a mile for overhead power at that time. It hasnt gotten cheaper. In 2000 it was around $20,000 a mile. I have to believe that getting power in the mountains would cost more.
I think Jim as being optimistic about the cost of a well. First you dont get to pick the depth, nor does your drilling company. The state Division of Water resources will tell you which aquifer you have to drill to. For example my house has a 440 foot well. it cost a little over $13,000 in 2007. My wifes parents place has a mandated depth of 900-1300 feet, so you can see it would cost alot more just being down north of DIA.
And the biggest thing is... not every piece of property gets to drill a well. period. You absolutely must know beyond a shadow of a doubt before you make the leap to purchase. I have lived on land that required us to have water delivered every week and kept in a cistern. Do you know what happens if a toilet is running over the weekend and you arent home? no more water. And if the road is too muddy for the truck to get in? no water. its a pain in the ass.
Personally I would do solar if the cost of electricity was going to be over say $10,000. But, I would absolutely need a well.
And no, in Colorado you cant just drill a well like you can in some back east and down south places. Here water is like Platinum its rare and expensive.
and alot of the mountain counties now require a minimum sqft to build. they dont want a tough shed community.
