These promo cards are only playable with a copy of Power Grid!
You can use all promo cards together or just the cards you like the most. All cards are compatible.
After preparing the power plant market and the draw pile of power plant cards, the chosen promo cards are shuffled into the pile of power plant cards. Finally the power plant 13 is placed as usual on top of the draw pile.
Transformer Station
The Transformer Station enables any power plant to supply electricity to an additional city.
When the Transformer Station is drawn, it will be immediately auctioned to the players regardless of the actual phase. After the auction draw an additional power plant card as replacement and place it into the market.
The leading player starts the auction by either passing or bidding at least 10 Elektro. The players continue the auction in clockwise direction until all but one passed.
The highest bidder pays his money and immediately connects the Transformer Station to one of his power plants by placing it below this plant. During phase 5 this power plant supplies one additional city when producing electricity.
If the player buys a fourth (fifth) power plant and decides to discard this power plant, he also discards the Transformer Station.
