Posting the link to this report below for folks here who haven't seen it.
Written by the President's Nat'l Infastructure Advisory Council, the report's purpose is to summarize the risks and provided a series of recommendations for action in order to prepare for and recover from a 'catastrophic power outage' - whether caused by a natural disaster, cyber/physical attack, EM event, or combination of any of those.
Although the PDF file linked below shows 94-pgs, the report itself is only 23-pgs, the remainder being an appendices of materials. There is one page containing the executive summary and an overview of the NIAC's recommendations, of which there are 7.
Let's just say there are several interesting findings and recommendations that are clearly based on the recent experiences of emergency-management agencies generally, and FEMA in particular, with such events as post-hurricane devastation in Puerto Rico and elsewhere (Texas, Fla., Katrina/NOLA), not to mention the effect that a no-notice cyber/physical attack shutting down the nation's power grid (or large sections of it) would have on a little-prepared/unprepared U.S. civilian population.
Here's a hint: read carefully and between the lines. Be alert to the use of bureaucratic 'buzz-words,' like 'shelter in place,' creating 'local resilience shelters,' and 'cascading effects' on the distribution of electrical power that create areas of 'haves' and 'have-nots' which could 'impact national security,' not to mention safety issues at the local level.
Think about what the reality 'on the ground' will be like in Chicago, L.A., NYC, et al, after any sort of extended 'black sky' event.
Note also the report suggests the 'new emerging preparedness standard' for individuals and families is no longer 72-hrs, but 14-days, during which you're expected to be on your own resource-wise. That appears to mean water, food, heat, and shelter.
Personally, I think 14-days is understating it, if Puerto Rico is any sort of lesson. Considering a 'catastrophic' power grid loss where the anticipated re-boot/restoration time is only estimated and theoretical, the minimum prep goal should be 4-weeks and, ideally, longer.
Anyway, here's the link to the PDF file, FYI:

Interesting and thanks. I'm not (yet) into total survivalist mode. I have some freeze-dried food and some bottled water I use and rotate fresh into the small stockpile. I even built a small 'luggable' solar setup (2 batteries and 2 100watt panels). So I'd probably be ok for a week or so.
But I've not convinced myself to go much beyond that, though I'm glad there are those that do, if for no other reason than I sponge off their ideas for short-term emergency relief. When you think about long-term messes like Puerto Rico, I'm not sure I want to be the one with the resources to be plundered. Even my very good, generous neighbors could get nasty if it came to feeding themselves and their families (including their dogs). For that matter, I'm not sure how I would react if things got really desparate: would I share anything? would I be willing to defend the things I had with deadly force? I would like to think I'd share if I figured it was short-term (like tornadoes around here, or power outages). I would also like to think I would defend my immediate neighbors especially short term, but I'm not sure.
