Gas compressors at my utility are electric; we have black-start capable (diesel) generators which in the event of a loss of station power are "supposed" to start but, good luck with that. And performing an actual black start is very tricky indeed for a variety of reasons. Adding in all of the weather issues that probably rendered their (likely non-winterized) backup equipment even less reliable than ours in my balmy area and, well... yeah, they were fucked.
