For my part, my own preparations worked well.
I do *not* have a generator (yet), but in this incident I did not really need one. There were rolling blackouts for several days, but the power would only be off for 30 minutes at a time every couple of hours, so I really didn't have any trouble worth mentioning. I *do* want to get a generator, though, even if just a small portable one. After Hurricane Ike I was with power for 6 weeks, but we had a portable generator that we used to run lights, TV, ACs, and refrigerator. I really miss the security of having a generator available.
For the blackout periods at night, I had plenty of light from a battery operated lantern and an oil lamp. I also had flashlights and candles, but those were not needed.
My food was fine. I may have eaten healthier than normal, because I broke into my canned food supplies and made a kick ass vegetable soup. I still have plenty of food.
Water I did OK on, but it could be improved. I had a pipe burst in the well house on my property and I had to shut off the water. But I had 8 gallons of water in the pantry to start with and used about 1 gallon per day, so it lasted through the worst of things until the roads cleared and the stores reopened. I now need to replenish my supplies. Still waiting on a PVC pipe connector so I can fix the well - when I went to the hardware store they were sold out of a lot of PVC stuff, almost as if everyone in the area had a pipe burst. Who would have guessed such a thing would happen?
For cooking I broke out the Coleman camp stove at one point. When I made the soup the power went out just as the pot was coming to a boil, so I put it on the Coleman to finish cooking rather than wait for the power to come back on.
I did run out of cat litter and had to just scoop the box out as best I could rather than replacing the litter like I normally do. I need to build up a small stock of litter for the future.
All in all, though, I came out pretty well and am pleased. There's a few things I want to improve on, but overall I think I did good.
