I’m not an electrical engineer, but my understanding is that it is not trivial to set up a island within the grid, because of the possibility that it will accidentally get connected to the grid, the power will be out of phase, and the out of phase electrical signals will fight each other. It sounds like Centerpoint has failed to maintain a real time awareness of what wires are down, this may make it impossible to be certain that they aren’t going to have that situation.
Of course, one would hope they had some plan about how to safely use them before spending almost a billion dollars on generators. But step one of the plan may have been “look at the outage map”.

Paywall, hope someone posts an alternate link.
