Back in the days when there were less maps we played every map back to back
Ooh a little higher, now a bit to the left, a little more, a little more, just a bit more. Oooh yes, that's the spot!
The deck is a variation on the original power plant deck and has such has plants so is as compatible with Power Grid Deluxe: Europe/North America as the original Power Grid deck is. i.e. it is not compatible out of the box, but you could pretend that garbage is natural gas and try it that way.
The power plant deck has no impact on the number of players. My personal view is play Power Grid with more than two players or use the The Trust rules or The Robots.
