The location consists of a single building and a large array of transformers. The building itself is a tall concrete structure with a garage door entrance and a barricaded side door. In front of the building, on its east side, is an empty dumpster and a short distance from the north side's outer wall is a collapsed power line frame.
There are eight NCR troopers guarding the area, one being a sergeant, some of which may be sleeping in the building.
