Historic energy mark reached last Saturday by the Itaipu Binacional hydroelectric plant is enough to supply the world for 19 hours!

Despite the water crisis that Brazil is facing, between 10 am and 14 pm last Saturday (9/10), the Itaipu plant reached the mark of 50 million MWh generated in the year 2021. This volume of energy would be enough to supply the planet Earth for 19 hours, Brazil for one month and seven days and Paraguay for two years and 11 months. “In a year of historic drought, Itaipu is operating at maximum efficiency”, says the Brazilian general director of Itaipu, general João Francisco Ferreira.

According to him, a relevant factor that contributed to this generation value was Itaipu's high productivity index, which has been fundamental for the hydroelectric plant to face a year of water scarcity.

Itaipu hydroelectric plant reaches the best annual energy index ever

Itaipu's average annual productivity index is, so far, at 1,0977 average megawatt per cubic meter per second (MWavg/m³/s), the best annual index ever. In July, the binational had broken the monthly productivity record, with 1,1221 MWavg/m³/s.

The high rates are possible thanks to the commitment of the binational teams of the Technical Area, making Itaipu meet the energy requirements of the two countries in the most efficient way possible, by generating energy at the best operating point of the generating units, where water consumption is smaller.

For this to happen, the machines must be available for generation, which requires coordinated work between the Operation and Maintenance areas of the plant.

The production of 50 million MWh is enough to supply:

Productivity is an index calculated by the ratio between the amount of energy generated and the turbine flow (the volume of water that passed through the generating units, measured in cubic meters per second). It is different from production, which means the absolute amount of energy generated in a given period of time (for example, the 50 million MWh produced since the beginning of the year until now).

to Itaipu

With 20 generating units and 14 MW of installed power, Itaipu Binacional is a world leader in the generation of clean and renewable energy, having produced, since 1984, 2,8 billion MWh. The hydroelectric plant is responsible for supplying approximately 11% of all energy consumed in Brazil and approximately 90% of the Paraguay.
