This is the third 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 having several ammunition boxes on the bottom tier floor level, near the exit to section 02.
Hoover Dam power plant 03 appears in Fallout: New Vegas.
