I have all the DLCs and took a mission on Ceres with the Power Station colony type and the colony spawned with several Wind Turbines. It continued to create more as wholesale shipments were made, and they happily generated power despite the lack of atmosphere
. In addition, the map description said that power generating structures could not be built, but Nuclear Plants were still available for construction (though there wasn't much need for them, given that the price of power was locked at 40$).
I imagine this was just an oversight regarding how Ceres would interact with that particular colony type, and it's doesn't really effect the game other than looking odd, but I figured I'd pass it along.
Besides that, having a lot of fun with the new campaign!
