Actually, their responsibility is to provide power for the citizenry en masse. Just like police are not obligated to protect individuals (court cases showed/proved that many times over), utilities are only obligated (in fact limited) to provide bulk power. Same for water, gas, etc. There are zero guarantees, either explicit or implicit. Anyone who ever lost cable for a week or two does not get a pro-rated refund for that time without service.
And clearing trees? The might not even be able to, not without permits, and even then, The County might claim sole power to trim trees and such. And considering how many miles of power-lines go over all sorts of territory (including private property), it’s unreasonable to expect the utility to have a landscaping service on retainer to clear trees and brush.
It was mentioned somewhere that even after all the hoo-ha is over, it’d take quite some time to inspect every bit of cable, in person and via helicopter, to make sure it’s all clear before powering it up. Now imagine how long it’d take to preemptively go and trim trees, sweep out brush (and put all the remnants… where?), and make sure everything’s “fireproof”?
Different topic… here in NYC, there are substations in and around the city that are fired up to provide supplemental power only when it’s most needed, eg, during a heatwave when everyone and his grandmother is cranking up the AC to “blitzkrieg”. No one wants them in Their Neighborhood, so of course they go and protest and sue and keep them shut down. OMGWTF, my kid might develop asthma from the noxious fumes coming from those substations! Keep them off!
And then when overloaded lines, transformers, everything, starts going >pop!< and some neighborhoods get brownouts and blackouts, they demand reparations! Pay me for all my food that went to waste! 2400bux for a fridge’s worth should cover it… (What were they keeping chilled, wild truffles?)
Sorry, but sometimes people are completely unreasonable. They want things to happen by magic, for free, and often in defiance of the laws of physics.
