Each player represents a power company, which works to supply electricity to cities. During the game, each player buys power plants at auction, buys resources to produce electricity in those power plants, and builds a network of cities to supply with electricity from his power plants. In the end, the player who supplies the most cities with power wins the game. (from the rules)
