Anons, these are two underground data centers. The one labeled Chrysler Group, LLC is….interesting as I understand it to be Microsoft.
Regardless, look at all the supporting infrastructure located on site. The AT&T bunkers posted in the last bread are much different. They do have power lines going to them through the woods as noted by another anon. But look at the pic I posted here and you can see the difference.
As yet another anon pointed out last bread, these could just be sites that provide access to the underground network and don't require much in the way of cooling or electricity.
