The Luiz Gonzaga Dam, formerly known as the Itaparica Dam, is a rock-fill embankment dam on the São Francisco River 25 kilometres (16 mi) downstream of Petrolândia in Pernambuco, Brazil. The dam was built for navigation, and hydroelectric power generation as it supports a 1,479 megawatts (1,983,000 hp) power station. It was constructed between 1979 and 1988; the last of its generators was commissioned in 1990. The dam is owned and operated by CHESF and was renamed in honor of Luiz Gonzaga, known as the "king of Baião" and "Gonzagão"
