Pursuant to the concession, we are required to meet specified quality standards with respect to the quality of the product (electricity) and the delivery of the product.  The quality standards relating to the product quality refer to the electricity’s voltage levels.  A disturbance occurs when there is a change in the voltage level.  The concession requires that the voltage level that we deliver must be 3x380/220 V; 13.2 kV; 33kV; 132 kV; 220 kV.
Following the privatization of our company in 1992, we have been able to improve our quality of service from an average of 22 hours of interruptions per customer and 13 interruptions per customer in 1992 to an average of 7.33 hours of interruptions per customer and 4.98 interruptions per customer in 2000, the last full year prior to the Argentine crisis.
