I'm sorry they're still without power but the power infrastructure is a mix of components no doubt installed over a period of decades. It cannot just be "fixed" overnight no matter how many people you throw at it. Brings to mind the classic book "The Mythical Man-Month".
After 30 plus yrs in S Fla I was without power on many occasions and watched power be restored all around me.As a utility worker I was aware of how the local”grid” was wired and understood why the guy behind me had poewer and I did not.
Yes it frustrating especially when after a hurricane,trop storm what ever I was working 14 hour days restoring service for others only to go home and take cold showers and live out of a cooler and on one occasion for 3 weeks.
Some of these people in Jersey and NY are unreasonable and as always act like self centered idiots.
A week with out power is not unheard of. When you look around you and poles are snaped off,on the ground and lines look like spahgetti dangling every where than guess what,its gona be a long f’en time so deal with it or get out.
