Jirau Dam
One of the largest power plants in Brazil
Location
History & Background
Commissioned in 2013, Jirau Dam is a hydro power plant located in Brazil with an installed capacity of 3.8 GW. It is operated by Energia Sustentável do Brasil. By installed capacity, it ranks among the top 5 power plants in Brazil.
Why It Matters
Jirau Dam is a critical piece of Brazil's electricity infrastructure, producing enough power for approximately 1.3 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
Jirau Dam produces effectively zero operating-stage emissions, displacing roughly 13.1 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 1.3 million US-equivalent households per year at typical capacity factor.
- Has been operating for 13 years.
