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 building near HELIOS One in the Mojave Wasteland. It is located southwest of Vault 11 and northwest of El Dorado Dry Lake.


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. The guard will instruct the player character not to enter the building or the fenced-in area, whereupon if they do, the soldiers will become hostile. No matter what reputation the Courier has with the NCR, the troopers will not allow entrance to either restricted area.

  • The friendly trooper, once triggered to approach, will chase the Courier until they can deliver the message, even all the way to the gates of Freeside.
  • The soldiers and the sergeant will respawn if killed.
  • Using the override chip will result in NCR infamy.
  • If the Courier is traveling with Boone as a companion, he will leave their party as soon as the Courier is detected within the restricted areas. If the areas are accessed covertly after completing the quest I Forgot to Remember to Forget, convincing Boone to be bloodthirsty, he will single-handedly murder every soldier inside the substation control room and remain a companion.
  • The gate to the fenced-in area is secured with an Average locked gate. Even if the lock is successfully picked while hidden, the NCR troopers will still become hostile.


The El Dorado substation appears only in Fallout: New Vegas.

Behind the scenes

The El Dorado substation is located in the same geographical area as the real world El Dorado Solar Power Plant substation near Boulder City, Nevada.

Spare Us the Cutter

Once the substation was turned on, a further quest stage was intended to kick in where the player would follow a Securitron to a nearby mountain ridge and watch the lights turn on at the Lucky 38. It's not clear why this sequence was cut (possibly due to lack of time, possibly as the actual graphical effect of the Lucky 38 is quite feeble compared to the script description: "the tower of the Lucky 38 lights up brilliantly in the distance" ), as full dialogue was recorded. Unused dialogue from Yes Man says turning on the reactor makes the Lucky 38 (and the strip itself!) independent from Hoover dam, and the reason to conquer that area would then be mere dominance of the region and to sell the unneeded electricity back to the NCR. It's not clear if this is canonical or not, as it seems to rob that questline from some of its urgency.

One thing that is peculiar with the sequence above is that Victor's dialogue lines have the wrong options set. Yes Man's are set so that each line is said once, and the dialogue cascades down. In Victor's case none of the lines have say once checked, meaning the conversation will never progress past the first line, which would be repeated ad infinitum. Even stranger, his later lines are all randomised despite them clearly being designed to be said in a specific order.

The Eldorado terminal still has all the original power on functions in the terminal itself, but a script overrides this so the player cannot actually use the terminal proper and instead shows a button prompt. This is especially strange as the message used in the final game is a lot vaguer and frankly somewhat confusing compared to the original terminal message that makes it clear you've now re-routed power to the Lucky 38's reactor, instead of the strange "power the substation" (the substation already is powered, surely?) message that is used instead. The message used also seems to be a repurposed message from the Lucky 38 Reactor itself from a stage (perhaps never implemented) when you could still access the reactor terminal and it used a button message/script to override the terminal on use. (The substation uses Lucky38ReactorActiveMsg when Lucky38ReactorInActiveMsg and Lucky38ReactorMsg all relate specifically to the actual L38 reactor).

Peculiarly a reference to this quest is also present in the quest vfreeformlucky38 (The Moon Comes Over the Tower). Stage 30 of that quest is inexplicably listed as "The Lucky 38 Reactor is being powered by the El Dorado substation", and points to an objective that no longer exists. VFreeformLucky38Note suggests originally the quest was perhaps planned as some kind of large scale reconnoitre of the Lucky 38 with the player possibly reporting back to the Followers on each aspect of the mysterious Lucky 38? It seems at some point the quests were separated, and then Moon Over Tower was cut to ribbons as well.
