UHE Jirau

Hydroelectric Power Plant I Rondônia

One of Brazil’s Largest Hydroelectric Power Plants

Located on the Madeira River, approximately 120 km from Porto Velho, in the state of Rondônia, the Jirau Hydroelectric Power Plant is one of Brazil’s largest hydropower plants, with an installed capacity of 3,750 MW, enough to supply more than 40 million people.


The facility has 50 bulb turbines housed in two powerhouses and a 361.6 km² reservoir. The main dam, a rockfill structure with an asphalt core, is 1,150 m long and 62 m high.


The electricity generated is transmitted to Brazil’s National Interconnected System (SIN) via high-voltage direct current (HVDC) transmission lines. The project was developed by the Energia Sustentável do Brasil (ESBR) consortium, with the participation of Eletrosul and Chesf, now AXIA Sul and AXIA Nordeste, together with Camargo Corrêa. Commercial operations began in September 2013, with the final turbine entering service in December 2016.
