IASC is obtained annually from a survey with consumers from all distributors concessions and licensees operating in the national territory. About 27,000 interviews are carried out. There are five variables evaluated: Perceived quality, Perceived value (cost-benefit ratio), Overall satisfaction, Trust in the supplier and Loyalty.

In 2020, Grupo Energisa won 3 of 9 categories in the ANEEL Quality Awards. ESS was the winner in the category of distribution companies with more than 400 thousand customers in the Southeast. EPB was the highlight in the category of the fastest growing among concessionaires in 2020 and also won the ANEEL quality award for best distribution company in Brazil in the category with more than 400 thousand customers.

Group Companies amongst the best of Brazil

In the main, the Group’s DisCos performed well in 1Q22, maintaining the excellent performance in previous quarters and presenting indicators below the DEC and FEC regulatory limits, with the exception of EMT.

ERO achieved its best ever historical series for both DEC and FEC. In March 2022 the DEC was 24.00 hours, down by 9.5 hours on March 2021. The FEC was 9.87 times, a 31.3% decrease, equivalent to 4.49 times.

EPB presented its best ever historical series of results for DEC and FEC. EMG and EAC, in turn, achieved their best ever historical FEC results in March 2022.

 EMT’s DEC and FEC rose in comparison with March 2021, owing to bad weather in the period September to December 2021 and the temporary difficulty to mobilize teams (now resolved) and equally unfavorable climatic conditions in the first quarter of 2022.

We have ramped up our maintenance plan since the last quarter of 2021, including tree-trimming and clearing work, and are making rapid grid improvements, including the installation of automatic reclosers and interconnecting feeders, which has enabled us to turn around the trajectory in the last 2 months, in order to meet the regulatory target.

The following table presents the results for the period:
