Olney Powerworks

 is a location added to Fallout 3 in the Broken Steel DLC pack.

It is an old power plant in the sewers of Old Olney guarded by Sentry Bots where you have to go in order to find a Tesla Coil for the Tesla Cannon.

The Powerplant could have recovered the Alien tech from Crash site, but this is highly debateable. Or they could have made the cells on their own by using some of the tech taken from the alien crash site (From the ufo of course)!

Notable loot

 * 3x12 Alien Power Cells can be found on the stove and table with the glowing electric globe in the room at the bottom of the pit where the Tesla Coil is found.
 * 2x9 Alien Power Cells can be found in the room past the tesla coil (upstairs). The hallway can be noted by the many servers along the walls. At the end of the hall there is a small room with tiny alien spaceship playground equipment to either side. Look above each of these small pillars to find two ammo boxes containing the Alien Power Cells.
 * Nuka Cola Quantum behind an average locked cell door, along with a Chinese Assault Rifle and some ammo.
