Dataset Information

Data available from 2000-01-01 to 2021-10-17

This dataset includes daily data on amounts of stored energy (EAR) by subsystems. Stored energy (EAR) represents the energy associated with the volume of water available in the reservoirs that can be converted into the generation in the plant itself and in all the plants downstream of the waterfall. The EAR magnitude takes into account the level verified in the reservoirs on the reference date. The maximum EAR amount represents the storage capacity if all reservoirs in the system were full. The amount of EAR for the downstream subsystem considers the use of water from the reservoir to produce energy in a downstream plant that is in a different subsystem.
