We are on a time of use plan with Southern, California Edison and the electricity during their prime time between 4 and 9 PM cost twice as much as the rest of the day. It has been suggested that it would make sense to lower the temperature sometime during the day, perhaps noon, to get the house cooled down so that the AC wouldn’t have to come on as soon after 4 PM as it would normally.

However, I have been experimenting with this, and it seems that there is no advantage. Has anyone figured out a formula that would take into consideration the difference in temperature between prime time and the rest of the time, plus the outside temperature, plus whatever other variables there are?
