Iberdrola signed a 70-year concession with the Government of Portugal in July 2014 for the design, construction and operation of three projects: Alto Tâmega, Daivões and Gouvães dams.[2]
Construction of the dam completed in July 2022.[3]
Dam
editGouvães Dam is 35 metres (115 ft) tall.[4]
Reservoir
editThe reservoir surface area for the dam has 3.4 km2 (1.3 sq mi).[4]
Power plant
editThe generating unit of the dam consists of four 220MW reversible turbine units with a diameter of 3,500 mm (140 in) and speed of 600rpm and producing 1468 GWh of electricity a year.
The maximum discharge capacity of the spillway located on the left of Gouvães dam is of 67 m3/s (2,400 cu ft/s). The dam also includes 6.5 km (4.0 mi) of tunnels along with a 750 metres (2,460 ft) shaft. The penstock is a concrete tunnel with a length of 4.7 km (2.9 mi) and diameter of 7.3 m (24 ft).[4]
