The Itaipu Hydroelectric Power Plant ended 2025 with a total production of 72,879 million megawatt-hours (MWh), a result that represents an 8,57% increase compared to 2024 and confirms the plant's ability to maintain high performance even in a hydrological environment marked by fluctuations.
According to the company, the volume generated throughout the year reinforces the project's relevance to regional energy supply during a period of challenges associated with climate variability.
The production recorded in 2025 would be enough to supply the entire planet's electricity demand for one day, illustrating the scale of the binational undertaking.
According to the data released, the 2025 production was impacted by inflow conditions to the Paraná River reservoir, which required operational adjustments throughout the year. Even so, the plant managed to optimize the use of available water, balancing energy generation, water security, and compliance with the operational guidelines of the electrical system.
Responsiveness
The performance achieved, the company emphasizes, demonstrates its ability to Itaipu to respond to different hydrological scenarios while maintaining high operational reliability.
The availability rate of the plant's generating units in 2025 was 96,29% of the time, exceeding the company's target of 94%.
Regarding the optimized use of equipment, the productivity (amount of energy generated for each m³/s of water that reaches the plant) recorded in 2025 was 1,100 MW average/m³/s, the best annual result in Itaipu's entire history.
The energy supplied by the plant to the Brazilian electrical system in 2025 accounted for 11,6% of all hydroelectric energy used in the country. Compared to other plants, Itaipu's supply to the Brazilian system in 2025 was 59% greater than the energy delivered by Belo Monte; 78% greater than that of Tucuruí; 2,75 times that of Santo Antônio; and 2,94 times that of Jirau.
The way the Itaipu power plant operates has resulted, when compared to the average, in a gain of approximately 3,92 million MWh in 2025 alone.
Shared energy
Of the total produced in 2025, 36% was destined for Paraguay, accounting for approximately 87% of the country's consumption. The remaining 64% was consumed by Brazil, representing about 7% of all the energy used by the country.
This energy sharing reinforces the strategic importance of the power plant for both countries, guaranteeing energy security and predictability in supply. In a context of increasing participation of intermittent sources, such as solar and wind, Itaipu's hydroelectric generation continues to offer stability and the capacity to adjust to the system's needs.

History and continued relevance
With over four decades of operation, Itaipu has accumulated a historical production of over 3 billion MWh, establishing itself as one of the largest hydroelectric power generators in the world.
Throughout this period, the power plant maintained a central role in shaping the Brazilian and Paraguayan electricity grid, contributing decisively to the supply of clean and renewable energy.
The growth in generation in 2025, even in the face of variations in inflows, highlights the importance of efficient management of the reservoir and the plant's assets.
In an increasingly complex electrical system, Itaipu continues to be a pillar of reliability, flexibility, and security, reaffirming its strategic relevance for the present and future of regional energy supply.
