Poseidon Energy

Easily the most powerful energy company in the world prior to the Great War, Poseidon Energy was an umbrella company with its fingers in virtually all forms of renewable and non-renewable power sources, long as they remained profitable.

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 (it seems Enclave members were employed by Poseidon as lobbyists). Most of Poseidon’s most promising projects never reached their final stages.

Though technically not part of the Enclave, many powerful corporations benefited from the Enclave’s actions and their research facilities were protected during the firestorm of 2077. Poseidon Energy was chief among these, as its facilities continue to be used by the broken remnants of the Enclave following the Chosen One’s assassination of the Enclave’s U.S. President and the destruction of their Poseidon Oil Rig headquarters off of the California coast.

Known Poseidon Energy companies
The PE wasn't a single, monolithic company, instead being a cartel of Poseidon corporations controlling various aspects of the global energy market... and cooperating with the Enclave. To facilitate communications (and terminate unlikely hostilities), the PoseidoNet system provided instantaneous communication between various Poseidon locations.

Poseidon Oil
Easily the most recognizable of the companies operating under the Poseidon name, PO did not limit itself only to excavation and pumping of oil - it also operated a number of nuclear power plants, one of which was the Reactor No. 5 in Gecko. Major installations belonging to this corporation were the Oil Rig on the Pacific Ocean and the Navarro refinery on the west coast of California.

Interestingly, Poseidon Oil seems to be a company with closest ties to the Enclave, with it's facilities housing the primary Enclave base and Navarro easily converted (or even already existing) into a military outpost. Also, together with the Enclave, it helped finance Senator Todd Peterson's secret bunker.

Poseidon Gasoline
Poseidon Gasoline was a company, that before the oil crisis, apparently operated some network of refueling stations, advertised with road maps for drivers.

Prometheus Coal
Prometheus Coal was probably a coal mines operator. At least it opened a coal mine called the Eagle's Rock mine complex in central Utah in 2039. It was eventually sold in 2066 to the U.S. government for a radioactive waste dump.

Other
Due to certain Agricola robot ties, it is possible that Poseidon took part in the Grand Canyon uranium mining business. It is also likely that numerous other companies operated under Poseidon Energy.

Known Poseidon facilities

 * The oil rig 175 miles off the coast of California was 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. It is referred at source files as a "station" also.
 * One of the largest known ships still afloat, the PMV Valdez was last seen anchored at the dock in San Francisco.
 * One of their atomic power plants, Poseidon Power Plant No. 12 remained in use after the war. In the year 2241, Reactor No. 5 was operated by ghouls settled there (they were able to tolerate the low radiation levels).
 * Private data network, PoseidoNet, was still in operation after the war, used by the Enclave. It was evidence of Poseidon's links with the government.
 * Olney Powerworks is stated to be "a division of PPE", which might be one of the branches of Poseidon Energy


 * Agricola lab at Eagle's Rock mine complex, Utah, carried Poseidon Energy logos.

Technologies
According to ACE the Enclave level of technology indicated that they had access to advanced manufacturing techniques and research facilities available to government agencies.

Poseidon-Enclave abandoned projects
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.

After the War, Poseidon did not exist as a real force in the world. However, tech scavengers like the Brotherhood of Steel and the Enclave still try in vain to decipher Poseidon plans and either confiscate them or turn them into working models, respectively.

There were a bunch of unfinished Enclave/Poseidon projects that science-oriented characters could complete (the story behind the projects was planned to help tie the Enclave to Poseidon).
 * Apollo - Laser Pistol
 * Ares - Plasma Spear
 * Artemis - Light Rail Gun
 * Athena - Advanced Power Armor, TL 9
 * Herakles - Power Fist
 * Hermes - Advanced Combat Armor, TL 9
 * Nemean - Sub-dermal ballistic armor implants
 * Phoenix - Sub-dermal thermal armor implants, like the ones received in Fallout 2.

Finished products

 * In the larger world's background, ODYSSEUS, also known as ULYSSES, was an extremely advanced AI created by Derek Greenway and developed by Poseidon Energy. Its two names emphasize the difference between Poseidon's Greek names and Greenway's Roman names (see also: Diana).
 * Agricola robot.
 * T6 Fusion Generator was a sixth generation TRIDENT class fusion generator from Poseidon Energy. It was relatively large and inefficient, mostly used for the powering of vaults and other small, isolated settlements. Present at a malfunctioning Vault in the van Buren tech demo. Despite the fact that Navarro was aPoseidon facility, there were built-in Wattz power generators.
 * ARGOS - the robotic juggernaut controlled by ODYSSEUS (mythological Odysseus' dog),

Other Greek mythology named objects
It is not certain, if Poseidon projects were CRB-S or Cerberus - 3 giant robotic dogs operated by Denver Police Department.

Names
Poseidon was the Greek god of the sea as well as horses and earthquakes. His weapon and symbol is the trident. Poseidon projects were codenamed with Greek mythology names:
 * weapons with gods names
 * implants with creatures names
 * robots with dog names (exception: AGRICOLA - Latin name for "farmer")
 * AI with hero's name
 * branch with titan's name

Trivia
Poseidon Industries is the name of a corporation frequently found in the works of Masamune Shirow, such as Ghost in the Shell, Appleseed, and Dominion: Tank Police.

Poseidon is the Greek god of the ocean.

Appearances in games

 * Fallout - Poseidon Gasoline present on the Boneyard map screen.
 * Fallout 2 - a lot of Poseidon Oil remnants as well as Poseidon Gasoline filling station at Navarro and presence of PoseidoNet.
 * Some Poseidon remnants, projects and products were planned to appear in van Buren. Poseidon Energy was a van Buren idea.
