I always hear the peak electrical power usage is in the summer in the late afternoon. But looking at my hourly electrical usage over the course of th e year, it is clear the peak residential usage for anyone with a heat pump is in the winter at night. My peak usage during the summer was less than 4 kW in any given hour. My winter peak was more like 12 kW and run like tha t from 7 PM to 11 AM. I saw this on six different days this season.
I realize residential heat pumps aren't the only sink of electrical power, but it sure seems like the difference between 4 kW and 12 kW for all those heat pumps would make a big dent in the power supply. Are the other usages of electrical power really that shut down on winter nights so that summer day usage is dominant?
