Stupid idea I’m afraid. There is nothing they would like more than immunity from liability. If they had that they would do nothing to prevent fires, improve their equipment or anything else. Giving people an undeserved pass seldom solves problems. It only assures that the problems will get worse.
I see you are ignorant in all the things you post about.
Of course they would love immunity. The state won’t give it to them. So the state gets blackouts during Santa Anas. You want them to “improve their equipment”. They have to string lines across mountains and deserts in order to bring electricity to rural areas and isolated cabins. If they have to make them impervious to high winds, at all times, then they have to spend billions. Are you or the state regulators going to agree to their rate increases in order to pay for that???? Or might it make sense for the state to subsidize the provision of infrastructure for those areas if it wants them upgraded?
Those are the issues. But as long as they have to keep rates low, provide coverage over all terrain in a large territory, and have liability for fires started by high winds, then you are guaranteed that they will use blackouts as a preventive measure.
Stay stupid, my friend.
