Conducted by ANEEL - National Agency of Electric Energy, the survey and the IASC Awards held on December 13 reflect the consumer perception about the quality of services provided by 63 distribution utilities in the country.
The 2012 edition involved 19,470 customers in 475 Brazilian cities, from September 3 to October 17 of this year. The statistical sample was proportional to the population served in each concession area.
The IASC survey is held every year to encourage improved quality of services provided by distribution operators. Since 2000, it awards the most efficient distribution operators in the customer’s opinion. These utilities receive from Aneel a certificate and a quality seal that can be used in promotional material.
