My folks back home have lights at night thanks to what we're doing here.NCR trooper, Fallout: New Vegas

The El Dorado substation is a power sub-station near HELIOS One, occupied by the New California Republic. Located south-west of Vault 11, north-west of El Dorado Dry Lake and to the north of HELIOS One.


Taking the incredible energy from HELIOS One and converting it into usable electricity occurs here, at the substation and adjacent transformer yard, both of which are guarded by NCR troops.


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 several feet 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.

As you approach the building you are told by a guard not to enter the building or fenced-in area. If they catch you doing either, they will shoot on sight.
