The dam was completed in 1981. It is owned by Companhia Portuguesa de Produção de Electricidade (CPPE). The dam is used for power generation and flood control.[1]

DamEdit

Raiva Dam is a 36 m tall (height above foundation) and 200 m long gravity dam with a crest altitude of 64.5 m. The volume of the dam is 85,000 m³. The spillway with 2 radial gates is part of the dam body (maximum discharge 2,000 m³/s). There is also a bottom outlet.[1]

ReservoirEdit

At full reservoir level of 61.5 m the reservoir of the dam has a surface area of 2.3 km² and a total capacity of 24.11 mio. m³. The active capacity is 14.71 (12)[2][3] mio. m³.[1] The reservoir of Raiva Dam serves as lower reservoir for the Aguieira pumped-storage power plant, which is located about 10 km upstream of Raiva dam.[4]

Power plantEdit

The hydroelectric power plant was commissioned in 1982[2][3][4] (1981).[5] It is operated by EDP. The plant has a nameplate capacity of 24[2][4][5] (20)[1][3] MW. Its average annual generation is 44.9[2] (44,[3] 44.8,[1][5] or 46[4]) GWh.

The power station contains 2 Francis turbine-generators (horizontal shaft)[4] with 13 MW (13 MVA) in a dam powerhouse located on the left side of the dam. The turbine rotation is 200 rpm. The minimum hydraulic head is 12 m, the maximum 18 m. Maximum flow per turbine is 80 m³/s.[2]
