What does it cost to operate a 1200W dishwasher for 2 hours, if electricity costs $0.065 per kWh? What will the cost be if you run the dishwasher during On-Peak hours? An Example:

Given: Power = 1200 W, time = 2 h Cost = $0.065 / kWh Required: Operating cost Analysis: C = P x t x c Solution: C=1.2kW x 2h x 0.065/kWh = $0.156 = 16 cents Statement: It costs 16 cents to run the dishwasher. (**keep in mind, there is dishwasher detergent to add as well!)

Run the dishwasher during On-Peak hours? Given: Power = 1200 W, time = 2 h Cost = $0.132 / kWh Required: Operating cost Analysis: C = P x t x c Solution: C=1.2kW x 2h x 0.132/kWh = $0.3168 = 32 cents Statement: It will cost 32 cents to run the dishwasher during On-Peak hours.
