off the top of my head...
defiance - aliens, terraformed planet post apocalyptic world, ties in with the game
extant - not sure haven't watched it yet
falling skies - aliens versus humans on earth, aliens destroyed lots of cities etc
continuum - season 2 was a little weak in my opinion
dominion - same basis as film - angels versus humans, not exactly sci-fi but close enough
I'm going to assume you've watch stargate universe (2 seasons), new battlestar galactica, chrome and blood, caprica etc
You've got the 100 but that's not exactly sci-fi in the strictest sense. Unfortunately for those of who love sci-fi (me included), it's slim pickings, everything seems to have gone reality tv or vampire/werewolf/witches for anything that isn't standard procedural cop/doctor/army type show.... hell there's nothing out there that I class as true sci-fi like the 80-90's had (star trek, babylon 5, knight rider etc), there is literally nothing out now with space ships being a key part of the plot for example.
