Itaipu hydroelectric dam aerial view with massive water release

Aerial view of the Itaipu hydroelectric dam during a massive water release, highlighting its grandeur and energy generation capacity.

About this subject

The Itaipu hydroelectric dam, located on the Paraná River at the border between Brazil and Paraguay, is one of the world's largest power plants in energy generation. Inaugurated in 1984, its construction required a joint multibillion-dollar investment and involved the removal of 50 million cubic meters of earth and rock. With 20 generating units and an installed capacity of 14 GW, Itaipu supplies about 10% of Brazil's energy consumption and 90% of Paraguay's demand. The massive water release visible in the image occurs during flood periods or maintenance, showcasing the controlled hydraulic force through the spillways. The dam stretches 7.7 km in length and stands 196 m tall, forming a reservoir of 1,350 km². Beyond electricity generation, Itaipu develops environmental and social programs, such as the "Cultivating Good Water" project, which recovers springs and promotes sustainability in the region. The plant is a symbol of binational cooperation and engineering, attracting millions of visitors annually to its visitor center.
