Are the power lines buried like in Europe where I live?
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.
