Poseidon Energy

Easily the most powerful energy company in the world prior to the Great War, Poseidon Energy had its fingers in virtually all forms of renewable and non-renewable power sources. Though most of the public knew that Poseidon was a huge corporation and didn’t particularly trust them, very few people were aware that several companies owned by Poseidon were given lucrative defense contracts by the U.S. government – or rather, by Enclave members working as lobbyists for their contracts. Most of Poseidon’s most promising projects never reached their final stages. In their paranoid dreams for a coup against the real U.S. government, the Enclave kept their special toys out of military consciousness until it was too late to actually use them. Now, Poseidon does not exist as a “real�? force in the world. However, tech scavengers like the Brotherhood of Steel and Enclave still try in vain to decipher Poseidon plans and either confiscate them or turn them into working models, respectively.

Known functioning Poseidon facilities:
 * One of their atomic power plants, Reactor No.5, remained in use after the war. It is now operated by the ghouls of Gecko who are able to tolerate the dangerous radiation levels.
 * The Poseidon Oil platform off the coast of California is the home base for the Enclave. It is unknown whether the platform was originally constructed for this purpose (presumably through a secret military-industrial contract) or was later converted.
 * One of the largest known ships still afloat, the PMV Valdez (Poseidon Merchant Vessel) was last seen anchored at the dock in San Francisco.
 * Their private data network, PoseidoNet, was still found to be in operation after the war. Used by the Enclave, it is further evidence of Poseidon Oil's strong government links.

Behind the scenes

 * Poseidon was the Greek god of the sea.

Appearances in games
The Poseidon corporation is mentioned only on the Boneyard map screen in Fallout, and appears much more often in Fallout 2. It would have probably appeared again in Van Buren.
