The Thunder Mountain power plant is a location in the Mire region of Appalachia in 2102.


The Thunder Mountain power plant served as a base for the Brotherhood of Steel. It was their main source of energy in Appalachia, powering Fort Defiance and the only place other than Fort Defiance occupied by the Brotherhood after Operation Touchdown. It was kept safe by a sonic device at the Fort, that was luring nearby scorchbeasts into kill zones. After the failed Operation Touchdown, the numbers of scorchbeasts grew to the point where the device failed to attract all of them.

On August 18th, 2095, the power plant received a transmission from Fort Defiance warning them of the imminent attack from the Scorched. The Brotherhood soldiers prepared as well as they could, sending scouts to confirm the warning. Whatever preparation they managed to do was in vain. The Scorced attacked in large numbers. The Brotherhood managed to hold to the next day. They had to abandon the facility roof, after the AAAs started to run low on ammunition. All of paladins and knights were killed by the Scorched and scorchbeasts. In the end, only Squire Rosen and Squire Gilden survived long enough to note the Brotherhood's bravery in a terminal, perishing soon after as the walls couldn't hold any longer.[1]

The fall of the power plant meant that Fort Defiance lost power, dooming it to fall just hours later.


Thunder Mountain power plant is the smallest power plant in Fallout 76. There are two cooling towers next to each other and easy access to the turbine hall for the generator section.

A quick way into the reactor section is through the main entrance, into the restrooms, and through the hole in the wall into the reactor chamber.

Notable lootEdit

  • Power armor chassis with T-series armor pieces - Enter the door labeled "Loading Dock" on the southeast side of the main building, go to the left. Armor is at one of the two power armor stations. Another single piece of power armor can spawn on a table in one of the tents in the south part of the power plant yard.


Thunder Mountain power plant appears only in Fallout 76.

Behind the scenesEdit

The Thunder Mountain power plant is based on the Mount Storm Power Station, near the real-world town of Bismarck, Grant County, West Virginia. As in the game, it has a man-made lake adjacent to it, and sits on land that abuts the Dolly Sods Wilderness.
