Christmas Eve day about fifteen years ago.
With a turbine or two off line, the power company used "rolling blackouts" of complete grids to ration the available electricity.
However, no one took into account that the 40, 50 & 60+ year old neighborhoods had 40, 50 and 60+ year old transformers. Since none of the homeowners turned off their thermostats, once power was turned back on to those "old" grids, the surge was WAY too much and the transformers couldn't take it. Sounded a lot like New Year's Eve not Christmas Eve.
The water bed's heat kept my wife and kids warm for a while but that eventually cooled down.
Needless to say we packed up the presents and stockings and spent the night at a friends house who lived across the street from a fire station.
Yep, if you were lucky enough to live in a grid that contained a hospital, fire department or police department your power wasn't turned off at all.
