Remove power plants 17, 18, and the »Step 3« cards from the old deck from the game.When preparing the deck, take power plants 1-8 from both decks and shuffle them together(14 cards). Now draw power plant cards one at a time. In each case, remove the first power plant of each number and place it next to the game board in a separate area for unused power plants. Place the second power plant of each number into the market (in two rows with the numbers in sequential order).
Never remove power plants 1 and 2 as there is only one of each.
Remove the »Step 3« card. Shuffle the remaining power plant cards and place them face down as a draw deck. Finally, place the »Step 3« card face down at the bottom of the deck. During the game, remove the first power plant of each number from the game placing it in the separate area for unused power plants. Players can examine this area to get an idea of what power plants may yet come up during the game. Depending on the number of players (as in the base game), remove a certain number of power plants from the game. To do this, take the second drawn power plant numbers (of course not the power plants for the starting market) and place them in the separate area for unused power plants. Do this until you have removed the required number of power plants. During the first game turn this takes a little bit effort, but later during the game it becomes easier«.
Every time you remove a power plant from the game (because they are too small or a player gets his fourth power plant), place it into the separate area for unused power plants.
