Fallout: New Vegas guide · Traveling north from Novac

HELIOS One is a pre-war solar power plant controlled by the New California Republic. Players are tasked by Fantastic and Ignacio Rivas with restoring the facility's power network in the quest "That Lucky Old Sun." The final decision allows the player to distribute power across the Mojave Wasteland or activate the plant's orbital defense weapon.
