Power Grid: The Stock Companies is an expansion for Funkenschlag: EnBW released in 2015 for 2–6 players, 120 minutes per game, and ages 13 and up. It was designed by Friedemann Friese and its main mechanics are Auction / Bidding, Network and Route Building, and Stock Holding.
The expansion Power Grid: The Stock Companies offers players a completely new game experience, specifically three new ways to play either Power Grid or Power Grid Deluxe. The main game is The Stock Companies: As shareholders, the players want to get control over different stock companies so they can acquire the greatest wealth. The two variants are a little bit closer to the well-known Power Grid experience. • The Biggest Electricity Distributors: In this first variant the players are shareholders who try to get shares of the most successful companies: the companies that supply electricity to the most cities. • The Competition of the Private Companies: In this second variant the players control their private stock companies and try to establish them successfully on the electricity market. They sell shares of their own companies to generate more cash and they are able to buy shares of other players’ companies. Thus, they can also earn a portion of the other players’ successes. If you own all Power Grid maps and the expansion New Power Plants, this expansion offers 222 new possibilities to play Power Grid and Power Grid deluxe. The rules for this expansion are based on module 9 "Shares" of the game 504. As 504 is a modular game system, we are able to take that module and mix it with Power Grid. The results are three different options to play this expansion. For the main game, we focused on the first option of the shares module, so you will discover a lot of surprises. Both variants are a little bit closer to the well-known Power Grid experience; they are for gamers who want to experiment with the game system.
Power Grid: The Stock Companies supports 2–6 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Power Grid: The Stock Companies is 120 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Power Grid: The Stock Companies for ages 13 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Power Grid: The Stock Companies has a complexity rating of 3.5 out of 5 from BoardGameGeek players, which makes it a medium-weight game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
