Itaipu hydroelectric dam aerial view with massive water release

Aerial view of the Itaipu hydroelectric dam during a massive water release, highlighting its magnitude and importance for energy generation in Brazil.

About this subject

The Itaipu hydroelectric dam, located on the Paraná River at the border between Brazil and Paraguay, is one of the largest in the world in terms of energy generation. Inaugurated in 1984, its construction involved a binational agreement and sparked environmental and social controversies, such as the displacement of communities and the formation of the reservoir. With 20 generating units and an installed capacity of 14 GW, Itaipu supplies about 15% of the electricity consumed in Brazil and 86% in Paraguay. The aerial image captures the moment of a spillway operation, when excess water is released to control the reservoir level, a common phenomenon during flood periods. The dam is an engineering landmark and a symbol of international cooperation, attracting visitors from around the world to see its imposing structure and its impact on regional development.
