Poseidon Energy

Poseidon Energy was a pre-War energy company that operated a number of oil rigs, factories, refineries, gas stations and power plants.

Background
Poseidon Energy was an umbrella corporation with its fingers in virtually all known forms of renewable and non-renewable power sources on both the east and west coasts of America, as well as research and development of new, more powerful weapons through their subsidiaries, so long as they remained profitable. One of its most notable features was the unified PoseidoNet, a national transfer system that provided instantaneous communication between various Poseidon facilities including Atomic Powerplant № 5, Control Station Enclave, Navarro, HELIOS One, the power plants of Appalachia, and other locations throughout the United States and possibly the world.

Energy mogul
Poseidon Energy dipped its arms into every energy source imaginable that, with help, could be weaponized or developed further. Poseidon Gasoline served as the face of gasoline, providing automobiles that still used the substance with it in the Northwest Commonwealth. Poseidon Oil focused on the mining and refining of what little reserves of oil still remained in the world. Poseidon Energy, while also focusing on gasoline and oil production, involved itself with a number of alternative energy sources as well, from solar energy to newly discovered forms of energy. They also had a branch in the Mexican area. The conglomerate was also not above buying out companies that delved into energy production, especially those founded by former employees of Poseidon.

In its drive to control the energy market, Poseidon cooperated with other companies, such as Atomic Mining Services, and was openly hostile to organized labor. When Poseidon workers organized a walkout at Poseidon Energy Plant WV-06, supported by the Associated Miner's Union, the corporation supported its on-site security director, Brent Olson, in his plan to humiliate the strikers and the union. Poseidon called in the National Guard, which proceeded to gas the protesters using HalluciGen, Inc.'s riot control gas. What the corporation hoped would be a violent riot that could be leveraged to further damage organized labor turned into bedlam, as the gas turned peaceful protesters into a rampaging horde that overran the perimeter, exposed soldiers to the gas, and eventually seized control of the plant. The Great War ended any further manipulations of the sort.

Defense contractor
Though much of the pre-War United States knew of Poseidon, few were aware that several Poseidon-owned companies were given lucrative defense contracts by the U.S. government – or rather, by Enclave members working as lobbyists to gain those contracts. However, most of Poseidon's most promising research projects never reached their final stages.

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.

Corporate relations
The corporation operated a number of daughter companies, which focused on different aspects of the global energy market:
 * Agricola was a subsidiary dedicated to uranium extraction.
 * Petró-Chico was "Un amigo de Poseidon Energy,", a Mexico-based oil refinement and distribution company.
 * Poseidon Oil focused on petroleum extraction and processing, although it also invested in other energy resources, including nuclear power.
 * Poseidon Gasoline was Poseidon's division focusing on distributing gasoline and operating gas stations.
 * Prometheus Coal focused on coal extraction.

Civilian

 * Poseidon Power Management System - An integrated power plant management package used extensively in Appalachia to operate its principal nuclear power plants.
 * U-235 outboard motor - A fusion powered boat motor for civilian use.

Military

 * AGRICOLA, a waste-disposal robot
 * APOLLO, a laser pistol
 * Archimedes I, a base defense system, operated from HELIOS One
 * Archimedes II, a mobile orbital laser strike system, operated by Euclid's C-Finder
 * ARES, a plasma spear
 * ARGOS, the "slave" robot for Odysseus
 * ARTEMIS, a light rail gun
 * ATHENA, an advanced power armor, tech level 9
 * CRB-S, "dogs" used by Denver City police department
 * HERAKLES, a model of power fist
 * HERMES, advanced combat armor
 * NEMEAN, sub-dermal ballistic armor implants
 * ODYSSEUS, the artificial intelligence in charge of Tibbets Prison
 * PHOENIX, sub-dermal thermal armor implants
 * SEMELE, an advanced plasma rifle
 * TRIDENT, fusion generators used to power vaults and other small, isolated settlements.
 * Solar cannon - crowd control device, sister project to the Tesla cannon.

After the Great War, Poseidon no longer existed as a real force in the post-atomic world. However, highly technological factions such as 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.

Appearances
Poseidon Energy appears in Fallout, Fallout 2, Fallout 3, Fallout: New Vegas, Fallout 4 and its Creation Club content, Fallout 76, Fallout Shelter, and the canceled Van Buren.

Behind the scenes

 * 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.
 * The company's slogan, "Begin your Odyssey with us," is a reference to Homer's epic poem, the Odyssey. The tale follows Odysseus' journey home from Troy after being cursed by the god Poseidon.
