My area (home) lost power for 6 days and the reason was strictly trees falling on lines, blocking roads, etc. About 2 years later, major clearing was done (including on a state road where they cut back exponentially). Larger poles, better wiring was replaced. We barely lost power again. Maybe for an hour during a bad thunderstorm. It can’t cost more than burying. Imagine blasting in the WM?
