The short answer
To shift electricity to off-peak hours: set the dishwasher delay-start to 10 PM+, run the clothes dryer after 9 PM, schedule the EV charger for midnight-6 AM, install a timer on the pool pump, and add a smart timer to a resistance water heater. These five appliances cover 30-50% of typical household kWh and can be fully automated for $50-150 in smart plugs.
Shifting electricity use to off-peak hours is the single best way to lower your bill if you are on a time-of-use rate plan. The off-peak window typically runs 9 PM through 7 AM and prices at 30-60% of peak rates. Most US households can realistically move 30-50% of their total kWh to off-peak with minimal lifestyle disruption — the trick is automating the shift so it happens without daily attention. This guide walks the 5 highest-leverage appliances to shift.
The 5 high-leverage shift targets
Dishwasher: 1-2 kWh/load. Set the delay-start function to 10 PM or later. Annual savings on TOU: $30-60. Clothes dryer: 2-4 kWh/load. Run after 9 PM or before 7 AM. Annual savings: $50-100.
EV charger: 8-12 kWh/day. Set the EV (or charger) to delay-start at 11 PM and finish by 6 AM. Most EVs have built-in scheduling. Annual savings: $200-400. The ev-home-charging-rate-plan-guide covers EV-specific TOU rates.
Pool pump: 6-15 kWh/day in season. Use a 24-hour timer to run only between midnight and 6 AM. Annual savings: $80-200. Water heater (electric, resistive): 8-15 kWh/day. Install a $30-50 timer (resistive heaters only). Annual savings: $50-120.
- Dishwasher: delay-start 10 PM+ → $30-60/yr
- Dryer: run after 9 PM → $50-100/yr
- EV charger: charge midnight - 6 AM → $200-400/yr
- Pool pump: timer for off-peak → $80-200/yr
- Electric water heater: timer or smart heater → $50-120/yr
Smart plugs + timers make it set-and-forget
A $20 smart plug + a 15-minute setup turns any 120V appliance into a TOU-aware device. Plug the appliance into the smart plug, schedule via the app, set-and-forget. Works for: portable AC, space heaters, fish tank heaters, garage refrigerators, holiday lighting.
For 240V appliances (dryer, EV charger, water heater), use a 240V timer or rely on the appliance built-in scheduler. Most modern dryers, EV chargers, and water heaters have schedulers built in.
Smart thermostats can pre-cool / pre-heat in off-peak hours and coast through the peak. Nest, Ecobee, and Honeywell T9 all have TOU-aware modes. The smart-thermostat-savings-nest-ecobee guide covers thermostat selection.
Verify the savings in your smart-meter portal
Most US utility portals show 15-minute interval data. After 30 days on TOU, pull the interval data and confirm: are you actually shifting load, or just thinking you are?
Common pitfall: scheduling appliances but forgetting one (e.g., the second freezer running 24/7 during peak hours). The interval data surfaces this immediately.
A whole-home energy monitor (Sense, Emporia Vue) provides circuit-level data that goes one step deeper than the utility portal. The home-energy-monitor-emporia-sense guide compares the two.
Recap
Bottom line
Shifting electricity usage to off-peak hours is the single most effective strategy on a time-of-use rate plan. Five appliances drive most of the available shift: dishwasher, clothes dryer, EV charger, pool pump, and electric water heater. Combined, they typically represent 30 to 50 percent of total household kWh and can be fully automated through smart plugs, built-in delay-start functions, and timers for $50 to $150 in one-time hardware investment.
Annual savings on a typical TOU plan range from $300 to $800 depending on baseline usage. EV owners on EV-specific TOU rates often save $400 to $700 per year just on charging cost. The time-of-use-rate-vs-flat-rate guide covers whether TOU is right for your household; the smart-thermostat-savings-nest-ecobee guide covers the HVAC pre-cool / pre-heat strategy that compounds the savings.
