Running Your Dishwasher at Night: The Verdict
So, is it cheaper to run your dishwasher at night? The answer depends on your specific situation. If you have a TOU pricing plan and can shift your energy consumption to off-peak hours, running your dishwasher at night can indeed save you money. However, if you have a tiered pricing plan, the difference in cost may be negligible.
Calculating the Savings
To calculate the potential savings, you need to consider the difference in energy rates between peak and off-peak hours. Let’s assume you have a TOU pricing plan with peak hours from 7 am to 7 pm and off-peak hours from 7 pm to 7 am. If the peak hour rate is 20 cents per kilowatt-hour (kWh) and the off-peak hour rate is 10 cents per kWh, you can calculate the savings as follows:
Assume your dishwasher uses 1.5 kWh per cycle
Peak hour rate: 1.5 kWh x 20 cents/kWh = 30 cents per cycle
Off-peak hour rate: 1.5 kWh x 10 cents/kWh = 15 cents per cycle
Potential savings: 30 cents – 15 cents = 15 cents per cycle
As you can see, the potential savings are relatively small, but they can add up over time.
