We had rolling blackouts since three power plants had issues with the cold. I was happy to find we didn't get hit long since my entire house is electric but my 93 year old grandma was hit 5 times for as long as 40 minutes at a time. Luckily her house is gas and she has a fireplace so warmth wasn't an issue but she has trouble seeing and with the gray weather she couldn't crochet or read.
