Investor Presentaiton

Hydroelectric Power Plants < 40 > Our hydropower generation complex comprises nine hydroelectric power plants (HPPs) and three small hydroelectric power plants (SHPPS), which are part of the Energy Reallocation Mechanism (MRE), a financial structure for sharing the hydrological risk. Our plants account for almost 2% of this system's entire hydro physical guarantee. Four of our nine plants operate with reservoirs (storage plants), while the others run on stream (run-of-river plants). The dispatch by hydroelectric plants in the ERM is determined by the National Electrical System Operator (ONS) and, in 2022, it was higher than in the previous year, due to higher rainfall in the period, when compared to the adverse hydrological scenario recorded throughout 2021.
