The Caniçada Dam (Portuguese: Barragem da Caniçada/HICA-Hidroeléctrica do Cávado-Caniçada; Portuguese pronunciation: [bɐˈʁaʒɐ̃j̃ ðɐ kɐniˈsaðɐ]) is a concrete arch dam on the Cávado River, the civil parish of , in the municipality of Vieira do Minho, in the Portuguese Norte (district of Braga. It is owned by Companhia Portuguesa de Produção de Electricidade (CPPE).[1]

History[]

The dam was completed and began functioning in 1955.[2]

In 196, approval was obtained to begin a program of observation of the dam, as proposed by the Laboratório Nacional de Engenharia Civil (Civil Engineering National Laboratory).[2]

Architecture[]

Caniçada Dam is a 76 metres (249 ft) tall (height above foundation) and 246 metres (807 ft) long arch dam with a crest altitude of 163 metres (535 ft). The volume of the dam is 90,000 cubic metres (3,200,000 cu ft).[2] The dam features a spillway with 4 gates over the dam with a maximum discharge 1,700 cubic metres per cubic foot (2,100,000 cu ft/m3) per second, and one bottom outlet with maximum discharge 142 cubic metres (5,000 cu ft) per second.[2][1]

Reservoir[]

At full reservoir level of 163 metres (535 ft) the reservoir of the dam has a surface area of 783 square kilometres (302 sq mi) of 6.89 (5.78)[3]km2 and a total capacity of 170.6 mio. m³; its active capacity is 159.3 (144,4)[4]mio. m³.[1] With the 144,4 mio. m³ water 32 GWh can be produced.[4]

Power plant[]

The hydroelectric power plant went operational in 1954. It is operated by EDP. The plant has a nameplate capacity of 62[3][4] (60[5][6]}} or 100[7]) MW. Its average annual generation is 337.4[4] (283,[6] 345[3] or 346[1][5]) GWh. The power station contains 2 Francis turbine-generators with 31 MW (34 MVA) each in an underground powerhouse 134[5] m below the surface. The turbine rotation is 300 rpm. The minimum hydraulic head is 77 m, the maximum 121 m. Maximum flow per turbine is 34 m³/s.[4] The turbines and generators were provided by Voith.[5]
