With the May power outages (I think about 800-900k) it was a mixture: one area did have damage to the main HV lines from a tornado, which is why they took so long to get power to that region I think. But most people its just the local service lines that were the issue. I haven't heard anything about damage to main HV lines this time, but I haven't done an exhaustive search either.
It also might be way different if the main issue is HV transmission lines vs local service lines.
