Hundreds of California hospitals ran on generators when power companies temporarily shut off services to prevent fires during windy weather, according to an article on the Modern Healthcare website.
A total of 248 hospitals were located in areas where power was turned off.
Power companies have undertaken the precautionary outages in recent years to prevent high winds from causing wildfire hazards like downed power lines.
In Northern California, Kaiser Permanente's Santa Rosa hospital and two medical office buildings temporarily lost power. It was restored the next day.
