Your prof has outdated information. TOU (Time of Use) rates are becoming more and more common. In 2019, TOU rates will be the default rate structure for new accounts in California. Many more states are following suite. Even if they're not the default, tons of places have opt-in TOU structures. EV owners and home storage owners use this a lot. Some states have even already adopted complicated shit only seen in C&I customers: demand charges. Basically, a portion of your bill will be dependent on your peak demand during a period (ie peak kW, not total kWh).
