During 2020 energy sales volume registered a 8.0% increase (from 20,179 GWh sold during the year ended December 31st, 2020 to 21,710 GWh sold in the year ended December 31st, 2021). The increase in volume is mainly due to the higher residential demand, partially offset by a drop in demand from commercial and industrial customers due to the effects of the pandemic. In turn, the average consumption per user remained stable while the number of customers grew by 1.1%.
