Power Grid: The New Power Plants – Set 2 is a complete set of power plant cards for Power Grid offering two variants to play:

in place of the original deck
paired with the original deck (to make for an unpredictable mix)
The power plants were released in 2014 for the 10th anniversary of Power Grid in the standalone base game Power Grid deluxe, which used a completely different graphic style. Now you can finally supply electricity with them with Power Grid, too!
