In Los Angeles, we have the “Time-of-Use Program” option from the power company. From their FAQ:

The prices are based on the time of day when the electricity is actually used, unlike the standard rate when the price for electricity is always the same.
A higher price is charged during “high peak” hours, which are between 1:00 p.m. and 5:00 p.m., Monday through Friday. The price for electricity during these hours is about twice the cost of the standard rate price.
Surrounding these “high peak” hours, are the “low peak” hours. “Low peak” hours are from 10:00 a.m. to 1:00 p.m. and again from 5:00 p.m. to 8:00 p.m., Monday through Friday. The price for electricity during these hours is slightly higher than the price charged on the standard rate.
During all of the remaining hours, Monday through Friday, and all weekend long, the price for the electricity you use is about one-half of the price for electricity on the standard rate. These hours are called “base” hours.
I was lucky in that my house came with a mechanical timer (as part of some Frankenstein solar system). It was easy to set it to turn off the hot water heater from 1 to 5pm. Don’t forget about daylight saving time, oh how I hate daylight saving time.

This worked fine except for the most weekends we would forget to reach into the box and turn on the hot water before during laundry or grabbing that all important weekend noon shower. Even the ridiculous note didn’t help.
