A power substation connected to the Thunder Mountain power plant. It is surrounded by a fence but can be accessed by a gate to the south or multiple gaps in the fence. A small shed is in the southwest corner of the substation. It contains a Teddy Fear wearing a collander as a hat and playing with a pair of drumsticks, some tools, and a desk with a broken terminal on it.
A deathclaw can usually be found fighting some giant ants in the fenced off area..
Thunder Mountain substation TM-02 appears only in Fallout 76.
