About this subject

The Itaipu hydroelectric dam, located on the Paraná River at the border between Brazil and Paraguay, is one of the largest engineering works ever built. Inaugurated in 1984, its construction took about a decade and involved approximately 40,000 workers. With 20 generating units and an installed capacity of 14,000 MW, Itaipu supplies about 10% of Brazil's energy consumption and 86% of Paraguay's. The dam is 7,919 meters long and 196 meters high, equivalent to a 65-story building.

The image captures the dam's spillway in operation, releasing a massive volume of water. Itaipu's spillway can discharge up to 62,200 m³ per second, which is 40 times the average flow of Iguazu Falls. This structure is crucial for controlling the reservoir level and preventing floods, especially during rainy seasons. The released water creates a curtain of vapor and foam visible from miles away.

Itaipu is not only an energy source but also a symbol of binational cooperation. The treaty that created the dam was signed in 1973, and management is equally shared between Brazil and Paraguay. In 2023, the plant reached the milestone of 3 billion MWh generated since the start of operations, a world record. Besides power generation, Itaipu develops socio-environmental projects, such as the Cultivando Água Boa program, which promotes the preservation of springs and the recovery of degraded areas.

The dam is also a major tourist attraction, receiving over 500,000 visitors annually. The complex includes a museum, a viewpoint, and a visitor center. The aerial view of the spillway in operation is one of the most impressive sights, showcasing the raw power of water and human ingenuity. Itaipu is considered one of the seven modern wonders of the world by the American Society of Civil Engineers.
