Difference here is that parts of the state not hit by the hurricane or otherwise saw inclement weather to any degree are also suffering power outages well outside the zone that would be acceptable. Texas (utility) companies doesn't want to invest in redundancies to give their power grid more endurance than it needs for anything more than a mild breeze and some light rain. Over 2 million people lost power, despite many of those people not seeing any other effects of the hurricane. These things don't happen anywhere else along the gulf coast where hurricanes are just as common, and just as heavy hitting. Texas just doesn't regulate their grid anywhere near the Federal standard everywhere else, and it shows with every year for the last 4 years running regional storms taking the grid out in areas far removed from the zone affected by the storm.
