Maybe this is common knowledge, maybe it's not and YMMV. It defintely doesn't work for every household, but I don't live a particularly unique life either.
Early in the summer I switched to time-of-use (TOU) billing with my electric company. That means during the 12 hours that I choose (8pm-8am) I get a rate of 10.28 c/kWh; and during the rest of time (8am-8pm) I pay a higher rate 30.08 c/kWh. The non-TOU rate is 19.32 c/kWh all day.
If you're like me and never home during the day, there is some serious money to be saved. I run my laundry, dishwasher, and generally cook during the off-peak hours; it's also when I turn down the A/C to sleeping temps instead of running it all day long. Since I'm not at home, I also don't run the TV or computer during the peak times.
This month my bill was down almost 60% from last year ($210 down to $130) with only some minor lifestyle changes. This dispite the fact that our summer has had more prolonged heat waves than previous years.
Hoping this helps a few people explore your options and save a few extra dollars! #finance source
