Power generators were used throughout the galaxy to supply large amounts of power to cities, bases, factories, starfighters, and planetary weapons. Smaller power generators existed which were able to provide continuous power for portable heavy weapons, vehicles, structures, and machinery. Both the Galactic Empire and the Rebellion used power generators at their bases to keep their communications arrays, base shields, turbolaser towers, and mining facilities functioning at peak levels. They were also used by numerous other factions such as the Zann Consortium and the Hutt Cartel.
