What is the annual power consumption of a Powered Anode Rod?

Since the amount of current used by the anode will vary from region to region due to the hardness of the water, it is impossible to give an exact answer. However, on average, the anode will use 10 KWh per year. If we take the average price of electricity in the United States, the cost to run the anode 24 hours a day all year round is $ 1.36.
