Itaipu hydroelectric dam aerial view with massive water release

Aerial view of Itaipu hydroelectric dam at twilight during a massive water spill, showcasing the sheer power of one of the world's largest hydropower plants.

About this subject

The Itaipu hydroelectric dam, located on the Paraná River at the border between Brazil and Paraguay, is one of the largest hydropower plants in the world. Inaugurated in 1984, its installed capacity is 14,000 megawatts, supplying about 10% of Brazil's electricity consumption and 86% of Paraguay's. The dam stretches 7,919 meters in length and stands 196 meters tall, forming a reservoir covering 1,350 km².

Water spillage occurs when the reservoir level exceeds storage capacity, typically during heavy rainfall. The spillway gates can release up to 62,200 m³/s, creating a powerful natural spectacle. The plant operates under the Itaipu Binational treaty signed in 1973, establishing shared management between the two countries. Generated energy is split equally, with each nation selling its surplus.

Beyond power generation, Itaipu runs environmental and social programs, including Atlantic Forest preservation and water quality monitoring. The dam is also a tourist attraction, receiving millions of visitors annually to see its facilities and the spillway in action. This image captures water gushing from the gates at twilight, highlighting the engineering marvel and the hydraulic power of the region.
