Should be possible, if I find anything more along that line, while I'm digging further. So far, after Hastings pointed me into the right direction, I finally found what a planet looks like in a savegame. I also found a flag, that tells the game, if it is neutral or not settled at all. Maybe higher values for that flag will mean in control by the Empire or the Alliance. So far I haven't found yet the energy amount for the planets. I once saw someone talk about on a site called 'Fly Steven's Rebellion ...' whatever, but it was just that you had to find the exact value that this planet has for energy in your savegame. When I mailed him and asked, if he could clarify that I got no answer at all. A few weeks after that I received a mail, that I had been added to his news service. I tried again just for the sake of it and it seems I was out of the mailing list pretty fast again But back to the topic, since the available enenergy for each planet gets dealed out at random in every new game, you could only do it this way: start the game, save it and then edit the planets you like.
