From the publisher's website:

“Power Grid deluxe” is based on the highly successful game “Power Grid”. However, it is not simply the same game with bigger, better and more beautiful components, but rather a version made especially for the 10th anniversary. Everything is bigger: the double-sided game board now offers all of North America and all of Europe, rather than just the USA and Germany. The customized wooden parts offer actual generators for the players and different shapes for the resources, among them natural gas instead of garbage. All the power plants have been changed and we added new resource refill cards to make refilling the resource table easier. The game is still Power Grid, with all the exciting auctions, the nerve-racking resource speculations, complex city networks and the tight competition among the players - all the way to the nail-biting end, as several players vie for the win. This is a box filled with good and proven parts in updated, new shapes. We wish you a lot of fun!
