This is the second of four power plant sections. All of the power plant sections have similar layouts: a large open area in the middle with two giant turbines, with a middle and top tier of catwalks and work areas along the walls and the floor forming the bottom of three tiers. Each tier has at least two sets of stairs connecting to the next tier up or down.
This section is distinguished from the others by the water testing site on the bottom floor and by the exit to the lower dam exterior on the middle tier.
There is very little of interest in each power plant section until the final quest, where the sections may become the location of a running battle between the New California Republic and Caesar's Legion.
The Hoover Dam power plant 02 appears only in Fallout: New Vegas.
