For example, if a 120 watt (0.120 kw) light bulb is used for 10 hours, the electric company will charge you for 1.2 kwh of electricity (0.120 kw * 10 hrs = 1.2 kwh). Activity: Obtain a Kill-a-watt energy meter from your teacher. Plug a device into the meter and measure the amps and kilowatts (kw) used for each device.

A hair-drier of power rating 1.5 kW is used for 20 minutes each day. (i) How many units of electricity are used? (ii) What is the cost, in cent, of using the hair- drier for six days? Answer. Six days corresponds to 120 minutes or 2 hours. The number of kWh = kW × hours = 1.5 × 2 = 3 kWh . Cost = 3 kWh × 11 cent per kWh = 33 cent

The standby heat loss, Q, having units of Btu/hr was converted into a demand reduction having units of kW, using the conversion of 3,412 Btu/hr per kW. The demand reduction occurred over a period of 13 hours per day, as this is the amount of time that the water heater is controlled by the time clock or then number of on-peak.

Even if the price ex works rose to £4.0 per kg, the cost per kW would only be £73 per kW, add (say) about 750 kg of supporting steelwork per 15 kW (a figure from past experience) at £1.30 per kg (galvanised) gives £65 per kW for supporting structures, £138 per kW for generators, rotors and tower.

Watts = Volts X Amps Volt-Amps = Watts. Multiply the cost per kWh times the kW of the appliance and you’ll get a cost per hour for using the appliance. Appliance Wattage W ÷ 1000 = kW Rate Cost per Hour= kW x Rate Hair Dryer 1500 W 1500 W ÷ 1000 = 1.5 kW $0.08 per kWh 1.5 kW x $0.08 per kWh= $0.12 per hour

The following calculations, applied to a hypothetical facility, demonstrate the costs of the PF penalty and the additional system losses. Applying the demand charges of approximately $5 per kW and efficiency losses to a facility with an average operating load of 750 kW, the potential costs associated with a poor PF are displayed in Figure 3.
