Poseidon Energy

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

Though most of the public knew that Poseidon was a huge corporation and never particularly trusted it, 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 to gain those contracts. 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 atomic 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 President and the destruction of their Oil Rig headquarters off of the coast of California in 2242.

Known Poseidon Energy companies
Poseidon Energy was not a single, monolithic company, but was instead a cartel of various Poseidon-owned corporations controlling various aspects of the global energy market; the PoseidoNet data transfer system provided instantaneous communication between various Poseidon facilites.

Poseidon Oil
Easily the most recognizable of the companies operating under the Poseidon name, PO did not limit itself only to the excavation and pumping of petroleum - 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, eventually used as the headquarters of the Enclave on the Pacific Ocean, and the Navarro refinery on the Pacific coast of California.

Together with the Enclave, Poseidon Oil helped finance Senator Todd Peterson's secret bunker. In addition, the majority of Poseidon Oil locations seemed to be specifically designed to be easily retrofitted with Enclave technology and personnel, with the notable exception of the Oil Rig's foyer floor.

Poseidon Gasoline
Poseidon Gasoline was a company that, before the energy crisis which had begun in the mid-twenty-first century, apparently operated some network of refueling stations, advertised with road maps for drivers.

Prometheus Coal
Prometheus Coal was a coal mine operator that opened the Eagle's Rock mine complex in central Utah in 2039. It was eventually sold to the U.S. government in 2066, to serve as a radioactive waste dump.

Helios Solar
Helios Solar was a division of Poseidon devoted to renewable energy in the 21st century, and had built a massive solar plant called Helios One in the Nevada desert. Advertisement of Helios One can be found throughout the Mojave, Poseidon Energy hail the solar plant as 'The dawn of a golden age'. By 2281, the solar plant was being fought over by NCR and the Brotherhood of Steel. Its potential energy output is actually higher then that of Hoover Dam since it can supply power to the entire Mojave Region. Like other insidious Poseidon projects, Helios One has a deadly ace up its sleeve; a massive superlaser titled "Archimedes II".

Petró-Chico


Petró-Chico was the arm of Poseidon Oil operating in the barren Mexican oil fields following the American take-over in the late 2050's. Based in Veracruz, Puebla, and Hidalgo, Petró-Chico oil flowed across the Rio Grande into the southern US, as far as Las Vegas, Nevada. Bearing the ominous label of "un amigo de Poseidon Energy", it is meant to showcase Poseidon's far-reaching and international hold over the world economy.

Other
Poseidon once attempted to absorb REPCONN Aerospace, but was contested by RobCo Industries. The administrative board of REPCONN saw off the Poseidon bid to take over the company as a decisive action, and sold out to RobCo in 2076.

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

Known Poseidon facilities

 * The oil rig 175 miles off the Pacific coast of California was the home base for the Enclave. It is unknown whether the oil drilling platform was originally constructed for this purpose (presumably through a secret military-industrial contract) or was later converted for the Enclave's use. It is also referred to in source files as a "station".
 * One of the largest known ships still afloat, the PMV Valdez was last seen anchored at the dock in San Francisco.
 * One of Poseidon's atomic power plants, Poseidon Power Plant No. 12, remained in use after the Great War. In the year 2241, Reactor No. 5 was operated by ghouls who settled there, due to the fact that ghouls thrive on radiation. The low, but continuous radiation levels emitted from the damaged power plant were a beacon to the ghouls to live there in the first place.
 * The corporation's private data network, PoseidoNet, was still in operation after the Great War, and was used by the Enclave. Its existence was evidence of Poseidon's close links with the federal government before the bombs fell.
 * Olney Powerworks is stated to be "a division of PPE", which might be one of the branches of Poseidon Energy


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


 * The Helios One plant in the Mojave desert continues to function in tandem with Hoover Dam, providing Las Vegas with plenty of power.

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

Poseidon-Enclave abandoned projects
Many of Poseidon’s most promising projects never reached their final stages. In their paranoid dreams of a coup against the real U.S. government, the Enclave kept their special toys out of the American military's knowledge until it was too late to actually use them.

After the Great War, Poseidon no longer existed as a real force in the post-atomic world. However, technology scavengers like the Brotherhood of Steel and the Enclave still tried in vain to decipher Poseidon's plans and either confiscate this technology or turn them into working models, respectively.

There were several 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 Fallout world's background, ODYSSEUS, also known as ULYSSES, was an extremely advanced Artificial Intelligence 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.
 * The T6 Fusion Generator was a sixth-generation TRIDENT-class fusion generator developed by Poseidon Energy. It was relatively large and inefficient, mostly used for the powering of the Vaults and other small, isolated settlements. Present at a malfunctioning Vault in the van Buren tech demo. Despite the fact that Navarro was a Poseidon-owned 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 the CRB-S or Cerberus projects - 3 giant robotic dogs operated by the Denver Police Department, were developed by Poseidon.

Names
Poseidon was the Greek god of the sea as well as horses and earthquakes. His weapon and symbol is the trident. Poseidon's projects often used codenames drawn from Greek mythology:
 * weapons had the gods names
 * implants were given greek mythological creatures' names
 * robots received dog names (exception: AGRICOLA - Latin name for "farmer")
 * A Poseidon-developed AI had a hero's name
 * Poseidon had a corporate branch with a titan's name

Behind the scenes
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 sea.

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.
 * Fallout: New Vegas - The Helios One solar plant was built by Poseidon Energy. As well as providing energy to the Vegas Area, it also doubles as a Solar Weapon, named Archimedes II.
