Poseidon Energy was an umbrella corporation with its fingers in virtually all known forms of renewable and non-renewable power sources. 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 around the world

Poseidon Energy dipped its arms into every energy source imaginable that, with help, could be weaponized or developed further. Initially focusing on gasoline and oil production, when the Global resource wars began Poseidon took steps to involve itself with a number of alternative energy sources as well, from solar energy to newly discovered forms of energy. 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 towards its human workers, attempting to replace all staff with protection robots. When Poseidon workers organized an occupational Strike at Poseidon Energy Plant WV-06 on the 22nd of October 2077. The corporation supported its on-site security director, Brent Olson, in his plan to humiliate the strikers and the union. Olsen proceeded to order the use of gas on the protesters using HalluciGen, Inc.'s riot control gas. Causing a violent riot and further damage. The riot 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 full control of the plant. This justified Poseidon to release protections and sentry bots into the plant in the early hours of the 23rd of October and kill all of the protestors.
