The hydroelectric plant’s installed capacity stands at 14,000 megawatts, generated through twenty turbines. Nearly 36% of the 2025 production was allocated to Paraguay, covering approximately 87% of the country’s electricity consumption, while Brazil received 64%, accounting for 7% of its national electricity supply and 11.6% of its hydropower consumption. In 2024, Paraguay’s share reached a historic peak exceeding 30% of total production, with the plant covering around 80% of the nation’s energy needs. In Brazil, Itaipú remains the largest energy supplier, producing 60% more than the second-largest facility, Belo Monte.
Itaipú’s accumulated generation since beginning operations in 1984 surpassed 3.1 billion MWh in 2025, setting records for the highest cumulative hydroelectric output worldwide. The plant’s performance validates its essential role in energy security for Brazil and Paraguay amid climatic variability and growing electricity demand. Its sustained output reinforces the importance of large-scale hydroelectric infrastructure in the transition toward renewable energy in South America.
