Unless electricity is actually that much more expensive during peak you're falling into the trap of simply artificially making the world worse for the purposes of controlling people's behavior.

People aren't stupid and will immediately recognize when the prices aren't connected to reality and resent you more than change their behavior for you. Most workers don't have access to cheap electricity because they're not home during the daytime hours, and setting up an elaborate series of timers is a non-solution.

You'll never get people to vote for the "everyone's electric bill goes up because fuck you for having a job" bill.
