@hawkeye10,
this is old tyme oil field savvy. We drill through saltwater and then hit oil and send down electrical logging equipment into saline water and keep it running and clean it up. I think they shut the power down with such a "preventive" concept in mind.
Engineers in the power industry and electrical railroads are mostly competent people. Youre just guessing, they get paid to know. Their mistakes are at a n extremely higher order than your knowledge of the subject so it may take days or weeks but itll be done right. I trust my field engineers with my clients money (and my paychecks and bonuses)
NY is losing several Billion dollars a day with shutdowns as this.
PS werent you and Billy the ones who were touting that someone is "Hyping the hurricane and harm it may cause"?
