It's a transmission problem not an energy problem (this time). There is
more than enough energy and generation capacity in the state. It just can't delivered to the last mile.
Based upon press releases from Entergy[0] (north of Houston/Centerpoint) a quarter million feet of wires need to be fixed. This doesn't include transformers, logging operations, etc.
I would estimate that Houston itself (Centerpoint) is probably dealing with a million+ feet of damaged transmission lines based upon the stats up here and their reported customer outage #s.
The area I (used to?) live in wont have power until the 14th because of the damage to the distribution infrastructure.
This is 99% a game of trees falling on lines and everything cascading from there.
