Summary
[edit]DescriptionAlbufeira da Barragem de Santa Luzia - Portugal (53017405260).jpg |
A Barragem de Santa Luzia fica situada na Região Centro de Portugal, no concelho da Pampilhosa da Serra, freguesia de Fajão-Vidual, junto à localidade de Casal da Lapa. Foi projetada por André Coyne e construída sobre o leito do Rio Unhais numa estreita garganta quartzítica e tem aproveitamento hidroelétrico. Foi inaugurada em 1942, tendo levado onze anos a ser edificada. Em 1931 começou a ser construída e em 1934 iniciou-se levantamento da barragem, que terminou em março de 1935. Possui 76 metros de altura e um comprimento de coroamento de 115 metros. A bacia hidrográfica de Santa Luzia tem uma superfície de 50 km2 e recebe também água da Barragem do Alto Ceira, canalizada através de um túnel de derivação com 6 945 metros de comprimento. Os trabalhos da barragem terminaram em 1942 com o fecho das comportas em novembro desse ano pela Companhia Eléctrica das Beiras. A central hidroelétrica está construída na localidade de Esteiro, a 3,5 quilómetros da barragem, e possui 4 grupos geradores com uma potência total de 24 MW, produzindo num ano normal 55 GW-h. .[1][2] A central hidroelétrica tem a particularidade de descarregar a água turbinada diretamente no Rio Zêzere. A descarga de fundo e a de emergência permanecem no rio Unhais. O nome da barragem advém da Ermida de Santa Luzia, uma capela existente nos penedos contíguos à barragem, no limite das freguesias de Vidual e Cabril. Esta capela foi erigida em 1930, por iniciativa de Francisco Pedro Simões, natural da Malhada do Rei, em cumprimento de uma promessa. <a href="https://pt.wikipedia.org/wiki/Barragem_de_Santa_Luzia" rel="noreferrer nofollow">pt.wikipedia.org/wiki/Barragem_de_Santa_Luzia</a> |
