The Monumental Jirau Hydroelectric Plant, Built on the Banks of the Madeira River in Rondônia, Boasts a Capacity of 3,750 MW and Supplies 10 Million Homes, Representing a Vital 3.7% of Brazil’s Hydroelectric Power, While Also Boosting the Local Economy and Committing to Sustainable Practices.
In the vast heart of the Brazilian Amazon, the Jirau Hydroelectric Plant rises as a modern colossus on the Madeira River. Located 120 km from the state capital, this monumental project, with an investment of R$ 19 billion, not only redefines the local landscape but also strengthens the national energy supply, benefiting more than 40 million people.
Inaugurated after a robust construction cycle that began in 2009, the Jirau Hydroelectric Plant stands out for its impressive installed capacity of 3,750 MW. Strategically positioned, the dam crosses the Madeira River with a length of 7,875 meters and a height of 62 meters, forming a reservoir of 361.6 km². This capacity allows it to provide enough energy to illuminate 10 million households, accounting for 3.7% of Brazil’s hydropower.
The Concept of Jirau Emerged in the 2000s When the Brazilian Government Recognized the Urgent Need to Expand the Country’s Energy Matrix
The concept of Jirau emerged in the 2000s when the Brazilian government recognized the urgent need to expand the country’s energy matrix, and was realized in 2016. The choice of the Madeira River was made due to its favorable characteristics and vast hydropower potential. The aim was not only to meet the growing energy demand but also to promote the sustainable development of the Amazon region, focusing on clean and renewable energy as an alternative to fossil fuels.

Somos auto suficiente em produção de energia e temos a maior tarifa do País, ficamos com todo o impacto ambiental e social e com a conta de energia cada vez maior, 😂😂😂😂
Literalmente o Brasil não é para amadores 😂🤡
Gostaria de saber pra onde está indo esses royalties das usinas hidrelétricas de Jirau e Santo Antônio, que aqui em Porto Velho, ninguém sabe.
O royalties de produção para Prefeitura de Porto Velho
O royalties de Distribuição para a Prefeitura de Piracicaba
Uma vergonha!, além de ter destruído o meio ambiente!, a energia de Rondônia é a mais cara do país!, com 2 usinas dentro do estado!
