I didn't say only do air conditioning during the peak times. You can definitely adjust the AC so that it runs on full during the peak times and cools things down a few degrees below ideal, then back it off and allow the temperature to rise a few degrees once electricity becomes more expensive.

Again, if the incentives are there, people will adjust.

This might work if you live in an airtight 1 m × 1 m × 1 m cube.

Running the aircon 5 degrees colder at 1pm and turning it off at 2pm will nullify the temperature difference in under 30 minutes.
