I finally managed to build a stable colony. I have built 2 natural gas generators a hydrogen generator and a coal generator. The problem is they don't always start producing energy even though I have sufficient fuel. With the 2 gas generators I have tried turning battery threshold for one at 0% and the other 100%. This way at least one has to work. But that's not happening.
How can I fix this?
I think you need my save file to see, because I don't know how to reproduce.
