And, sometimes, it isn't crazy cheap (especially when there's a cold snap in the south and everyone turns on their heat pumps)
Ahh, I did not realize that. That makes more sense than 3.5c/kWh. It is really interesting to look at this information and see how it changes from minute to minute.
It basically pushes the burden of averaging to the consumer -- except the consumer gains the advantage of being able to adjust their usage patterns to take advantage of the cost fluctuations.
