Usina Hidrelétrica de Rosal

The Rosal Hydroelectric Power Plant is a Grupo Rede de São Paulo venture that started operating in December 1999. It was acquired by CEMIG in December 2004, being the first CEMIG plant outside the state of Minas Gerais. It is located on the Itabapoana River, between the municipalities of São José do Calçado in the south of Espírito Santo, and Bom Jesus do Itabapoana, northwest of Rio de Janeiro. The 55 MW generated are injected into the National Interconnected System through Escelsa Centrais Elétricas with a transmission line for the municipality of Alegre, in Espírito Santo and another for the municipality of Mimoso do Sul in the same state. The Plant has two Francis-type generating units, with a nominal drop of 184.4 meters, and a gravity-type concrete dam, 214.5 meters long and 34 meters high.
