In order to compare the electricity tariffs internationally, new methodologies have been introduced and the exchange rate was used to calculate a common currency. We selected 5 countries, which were Korea, France, England, Japan and the U.S.A. The new methodologies involved using a unit price from sales at power companies in selected countries and a unit price from electric charges for proxy customers.\r\n\r\nA unit price from sales is the total revenue from electric sales divided by the total amount of sales. The unit price in France was the lowest and next lowest was in Korea, during 2000 to 2002. A unit price from electric charges is the total expenditure of a proxy customer divided by the total amount of electric consumption. The residential unit price and the industrial unit price were compared. The unit price from KEPCO was the lowest.
