Olney Powerworks

Olney Powerworks is a location added to Fallout 3 in the Broken Steel add-on. The player is sent here in order to find a Tesla coil during the Shock Value quest.

Layout
It is an old power plant in the Old Olney sewers. It was owned before the Great War by PPE.

Notable loot

 * 3x12 alien power cells. One can be found on each of the following: the stove, the table next to the stove and the table with the glowing plasma ball in the room at the bottom of the pit where the Tesla coil is found.
 * Around 8 alien power cells can be found in 2 ammunition boxes eachm in small room past the Tesla coil (upstairs), next to two Mark IV turrets.) There are considerably more alien power cells (around 45) with the Scrounger perk,

Appearances
Olney Powerworks appears only in the Fallout 3 add-on Broken Steel.

Bugs
If you destroy the sentry bots before shutting them down with the terminals, then use the terminal to shut them down (after them already being disabled), they'll have the "Talk" option instead of the "Search" option. Shooting them once or striking them with any weapon will give you XP as if you killed them again.
