Actually maybe a well insulated house could be considered a "thermal battery". If you look at the CAISO reports, a significant chunk of the duck curve is related to heating/cooling. If you had a super well insulated house, you could do the heating/cooling during the day.

Instead today, people fire up the AC on overdrive when they get home in the evening to cool/heat the place down/up. What happens if your Nest could just fired it up at 3pm while the sun was still shining.

In fact the opposite is done today to take advantage of early morning peak pricing, commercial buildings cool/heat at 3am to get optimal energy pricing.
