In my town the temperature dropped to like 15 degrees on Christmas Eve and due to demand one of the substations exploded. There were about 10,000 people without power from 10am to 10pm on Christmas Eve. That additionally caused a lot of commercial buildings to have pipes burst which depressurized the water system. That caused main underground water lines to collapse and around 5k people had no water for 3 days. Similar events happened in a few other areas as well.
