Itaipu hydroelectric dam aerial view with massive water release

Aerial view of the Itaipu Hydroelectric Dam during a massive water release at twilight, showcasing the power of the world's largest energy generator.

About this subject

The Itaipu Hydroelectric Dam, located on the border between Brazil and Paraguay, is the world's largest generator of clean and renewable energy, with an installed capacity of 14,000 MW. Inaugurated in 1984, its construction took 12 years and involved about 40,000 workers. The main dam is 7,919 meters long and 196 meters high, forming a reservoir that spans 1,350 km². The water released in the image corresponds to the spillway, which can discharge up to 40,000 m³/s, equivalent to 40 Olympic swimming pools per second. This mechanism is activated during flood periods to control the reservoir level and avoid overloading the turbines. Itaipu supplies about 10% of Brazil's energy consumption and 85% of Paraguay's, symbolizing binational cooperation. The plant also stands out for environmental initiatives, such as planting over 40 million trees in the watershed region.

Frequently Asked Questions

What is the generation capacity of the Itaipu dam?

Itaipu has an installed capacity of 14,000 MW, generating about 90 million MWh per year, enough to power 15 million homes.

Why is water released through the spillway?

The release occurs to control the reservoir level during heavy rainfall, preventing overflow risks and ensuring structural safety.

How many countries benefit from Itaipu's energy?

Two countries: Brazil and Paraguay. The plant is jointly managed by Itaipu Binacional, supplying about 10% of Brazil's consumption and 85% of Paraguay's.
