What is Itaipu Dam?

June 21, 2024


Itaipu Dam is a hydroelectric power plant located on the Paraná River, on the border between Brazil and Paraguay. It is one of the largest dams in the world and plays a crucial role in providing energy to both countries. In this glossary, we will explore the history, construction, and significance of Itaipu Dam.


The idea of building a dam on the Paraná River dates back to the 1960s when both Brazil and Paraguay recognized the need for a reliable source of energy. Construction of Itaipu Dam began in 1975 and was completed in 1984. The dam was a joint project between the two countries, with each contributing equally to its construction.


Itaipu Dam stands at a height of 196 meters and has a length of 7,919 meters. It has a total of 20 generating units, each capable of producing 700 megawatts of electricity. The dam’s reservoir covers an area of 1,350 square kilometers and has a capacity of 29.3 billion cubic meters of water.


Itaipu Dam plays a crucial role in providing energy to both Brazil and Paraguay. It is estimated that the dam generates around 90% of Paraguay’s electricity and 15% of Brazil’s. The dam also helps reduce greenhouse gas emissions by providing clean and renewable energy to the region.

Environmental Impact

While Itaipu Dam provides clean energy, it has also had a significant impact on the environment. The construction of the dam led to the flooding of a large area of land, displacing thousands of people and causing the loss of biodiversity in the region. Efforts have been made to mitigate these impacts through reforestation and conservation programs.


Itaipu Dam has become a popular tourist destination, attracting visitors from around the world. The dam offers guided tours that provide insight into its construction, operation, and environmental impact. Visitors can also enjoy panoramic views of the dam and its surrounding landscape.

Technological Innovation

Itaipu Dam is known for its technological innovation in the field of hydroelectric power generation. The dam’s turbines are among the most efficient in the world, and its control systems are state-of-the-art. Itaipu Dam serves as a model for sustainable energy production and management.

International Cooperation

The construction and operation of Itaipu Dam have strengthened the relationship between Brazil and Paraguay. The two countries have worked together to manage the dam effectively and ensure its continued success. Itaipu Dam stands as a symbol of international cooperation and mutual benefit.


Despite its many benefits, Itaipu Dam also faces challenges. The dam’s reservoir has experienced fluctuations in water levels, leading to concerns about its long-term sustainability. Climate change and deforestation in the region also pose threats to the dam’s operation.

Future Prospects

As technology advances and the demand for clean energy grows, Itaipu Dam is poised to play an even greater role in the region’s energy supply. Efforts are being made to improve the dam’s efficiency and sustainability, ensuring that it continues to provide reliable and renewable energy for years to come.


In conclusion, Itaipu Dam is a remarkable feat of engineering that has had a significant impact on the energy landscape of Brazil and Paraguay. Despite its challenges, the dam remains a vital source of clean and renewable energy for the region. Its technological innovation, environmental impact, and international cooperation make Itaipu Dam a model for sustainable energy production.
