History & Background

Commissioned in 1984, Tucuruí Dam is a hydro power plant located in Brazil with an installed capacity of 8.4 GW. It is operated by Eletrobras. By installed capacity, it ranks among the top 5 power plants in Brazil.

Why It Matters

Tucuruí Dam is a critical piece of Brazil's electricity infrastructure, producing enough power for approximately 2.9 million US-equivalent households per year. Hydroelectric facilities are dispatchable: their output can be ramped up and down quickly to match grid demand, which makes them especially valuable for balancing the rest of the system.

Environmental Impact

Tucuruí Dam produces effectively zero operating-stage emissions, displacing roughly 29.3 million tonnes of CO2 per year compared to a coal-equivalent. Large hydroelectric projects do reshape rivers and ecosystems: they trap sediment, alter water temperatures downstream, and can block fish migration. The size of these impacts varies dramatically by site.

Fun Facts

  • One of the 10 largest power plants in Brazil.
  • Produces enough electricity to power roughly 2.9 million US-equivalent households per year at typical capacity factor.
  • Has been operating for 42 years.

About Hydroelectric Power

Hydroelectric power plants use the kinetic energy of flowing or falling water to generate electricity. They are renewable, produce no direct emissions, and can provide reliable baseload power or flexible peaking capacity.
