The average electricity rates that are charged by investor-owned utilities are affected by external factors that cannot be regulated by direct management. Results of a multiple regression analysis of three California utilities in relation to 96 utility companies indicate that the variations in average charged electricity rates were caused by customer and territorial aspects. Furthermore, the costs of operations and the supply of hydro and fossil fuels were also found to affect the average electricity rates.
