Itaipú dam supplied nearly 88% of Paraguay's energy in 2025, report shows

The Itaipú Binacional hydroelectric dam was the primary source of electricity for Paraguay in 2025, supplying a remarkable 87.6% of the country's total energy consumption. This reliance is detailed in the dam's recently published Annual Report 2025.

Financially, the dam's operations significantly benefited Paraguay. The Paraguayan state received over $411 million through royalties and compensation for energy ceded to Brazil. These funds are crucial for financing regional governments and municipalities.

The report highlights the dam's increased generation, which rose by 8.9% in 2025 compared to the previous year. This achievement was noted despite challenging climatic conditions. The dam's administration celebrated its technical efficiency, financial stability, and social progress, as stated in the report released by the binational entity's Brazilian side.

In contrast to Paraguay's heavy dependence, Itaipú's output represented only 6.7% of Brazil's energy consumption. The report also confirmed that the electricity tariff remained stable at $19.28/kW, a result of diplomatic negotiations. The dam continues its modernization projects and explores advancements in green hydrogen and floating solar energy, while also funding social initiatives in health, biodiversity, and indigenous communities.
