Rolling blackouts in Texas (or elsewhere) are not caused by storm damage.
Rolling blackouts are administrative actions (turn off power, turn on
power) taken by the system operator. They can "turn on" the power after a
rolling blackout with a switch because there is no damage to the outside
plant.
In California, they use rolling blackouts BEFORE wildfires to prevent
power line sparking causing wildfires. Not because of damage to the
outside plant. In Texas, they use rolling blackouts because they didn't
have enough generation capacity online.
Again, the rolling blackouts in Texas is not due to storm damage. Its
because natural gas power generator plants froze, and Texas is an
separate electric grid from the rest of North America due to political
reasons. That's why the rolling blackouts stop at the Texas border
(approximately).
Chicago Illinois (3rd largest metro area) power plants haven't frozen, and
can use power from states across the north-central US grid.
Most of Texas is rural and cheap. Power lines are built above ground.
Only in a few dense urban areas, i.e. downtown Dallas or downtown
Houston, are power lines underground for aesthetic reasons.
