Overview
Itaipu (Parte Brasileira) is a 7,000 MW hydroelectric power plant located on the Paraná River at the Brazil-Paraguay border. It is one of the largest hydroelectric facilities in the world, supplying clean energy to both countries.
Itaipu (Parte Brasileira) is a massive hydroelectric power plant situated on the Paraná River, forming part of the Itaipu Binacional project shared between Brazil and Paraguay. With an installed capacity of 7,000 MW, it ranks among the largest hydroelectric facilities globally, playing a critical role in Brazil's energy matrix. The plant is located near Foz do Iguaçu, in the state of Paraná, and its operational status is active. The plant utilizes 20 generating units, each with a capacity of 700 MW, driven by the hydraulic potential of the Paraná River. The technology is based on conventional hydroelectric turbines, and the facility benefits from a large reservoir that ensures stable power generation. Brazil's regulatory framework for hydroelectric plants includes environmental licensing and water use permits under the National Water Agency (ANA) and state environmental agencies. Environmentally, Itaipu provides significant benefits by displacing fossil fuel-based generation, avoiding millions of tons of CO2 emissions annually. The reservoir and surrounding areas support local biodiversity and are managed under environmental programs. The plant supplies electricity to millions of households and industries, underpinning Brazil's economic development and energy security.
Environmental context
As a large hydroelectric plant, Itaipu has a low carbon footprint compared to fossil fuel plants, but its reservoir creation has altered local ecosystems and affected aquatic biodiversity. The facility operates under strict environmental monitoring to mitigate impacts on water quality and fish migration. Its location in a subtropical region with high rainfall ensures consistent water availability, supporting reliable renewable energy generation.
