I've never had to hook up a new place to infrastructure (though I did have to price it out once before deciding it wasn't worth it), but yeah, it'll just be a flat cost.

To steal a metaphor from my other comment, though, the way it works right now is like if you could grow a bunch of tomatoes over the summer and drop your extra off at the grocery store, and then when the winter comes around, you just went and grabbed the same amount off their shelves. It's disregarding the fact that tomatoes cost more in the winter cause they have to be imported or hothouse grown.

To continue the metaphor, though, they would need to pay an employee to check all your tomatoes to make sure they were safe to eat and up to standards, and make sure there aren't pests hitching a ride that would destroy their own tomatoes. This is made a little more complicated by the fact that grocery stores can and do charge more for those tomatoes during the winter, but power companies usually have to offer a flat rate. What they are trying to do now is price all of that in, so instead of getting the year-round on-the-shelf price, you'd get the summer wholesale price. At that point, you'd decide if you still want to sell your tomatoes, or you could start canning.
