The Jirau Dam is a rock-fill dam with an asphalt-concrete core, in the Madeira River in the state of Rondônia, Brazil. The dam's hydroelectric power stations have 50 turbines each 75 MW resulting total installed capacity of 3,750 MW. The power plant's first unit was commissioned in September 2013,[1] the 16th in November 2014,[2] 24th in February 2015,[3] the 41st in December 2015,[4] and the last in December 2016.[5] Most of the power is designed to be exported to south-eastern Brazil via the Rio Madeira HVDC system.

The dam is part of a planned four power plant Madeira river hydroelectric complex, which will consist of two dams in Brazil (3,580 MW Santo Antônio Dam at the city of Porto Velho and Jirau), a third on the border of Brazil and Bolivia, and a fourth station inside Bolivia. Two of these, Santo Antonio and Jirau, are already operating, while the smaller upstream dams are still in the planning stages. In part due to the 2001–2002 power shortage in Brazil, construction of both dams was accelerated in 2009. The total estimated cost of the two facilities currently under construction is $15.6 billion ($8 billion for Jirau), including about $10 billion for the civil engineering and power plants, and $5 billion for ship locks, transmission lines, and environmental re-mediation.[6] The Madeira river hydroelectric complex is part of the Initiative for the Integration of the Regional Infrastructure of South America, an effort by South American governments to integrate the continent's infrastructure with new investments in transportation, energy, and communication.[7] Construction on the project was temporary halted in March 2011, February 2012 and April 2013 due to worker riots or strikes.[8][9]

The Brazilian Development Bank approved an additional US$1.6 billion for the project in September 2012. The extra funding will add six more 75 MW bulb turbine-generators to the power station (a total of 50) and pay for transmission lines.[10]
