Edenor is Argentina's largest electricity distribution company, serving approximately 3.4 million customers across the northwestern Buenos Aires metropolitan area and northern Buenos Aires city through an exclusive concession granted in 1992 with a 95-year term. The company generates revenue by billing customers—divided into residential, commercial, industrial, and low-income categories—for electricity consumption at tariffs regulated by Argentina's national electricity regulator, with residential users accounting for approximately half of sales and industrial users and large commercial wheeling customers making up another one-third combined. Edenor operates an extensive distribution network of high-, medium-, and low-voltage lines and substations to deliver electricity purchased from generators, and its core profitability is affected by technical and non-technical losses (including energy theft), collection rates on customer billings, and regulatory penalties tied to service quality metrics such as interruption frequency and duration.
