The dam Castelo do Bode ( Portuguese Barragem de Castelo do Bode ) dams the river Zêzere , a tributary of the Tejo , to a reservoir ( Portuguese Albufeira da Barragem do Castelo do Bode ). It is located in the region of central Portugal in the Santarém district , about ten kilometers southeast of the city of Tomar and about five kilometers north of the small town of Constância .
The first studies on the construction of a hydroelectric power station on the Zêzere were undertaken in the early 1940s. The project to build the dam began in 1945. The construction was completed in 1951. In addition to generating electricity, the dam also provides drinking water and flood protection. It is owned by the Companhia Portuguesa de Produção de Electricidade (CPPE).
Barrier structure
The barrier structure is a weight arched concrete wall with a height of 115 m above the foundation level . The top of the wall is at a height of 124.3 m above sea level . The length of the top of the wall is 402 m. The volume of the structure is 430,000 (or 460,000) m³. The dam was designed by André Coyne .
The dam wall has both a bottom outlet and a flood relief with two gates. A maximum of 4,000 m³ / s can be discharged via the flood relief. The design flood is 4,750 m³ / s; the probability of this event occurring has been determined to be once in 1,000 years.
Reservoir
With a normal storage target of 121 m (maximum 122 m at high water), the reservoir extends over an area of around 32.91 (or 35) km² and holds 1.095 (or 1.1) billion m³ of water - of which 900, 5 million m³ are used.
The reservoir is the largest freshwater reservoir in Portugal and has a maximum length of 60 km. He serves u. a. also the drinking water supply of the greater Lisbon area . Two pumping stations take up to 625,000 m³ daily from the lake and direct the water to a waterworks in Asseiceira , from where it is piped to Lisbon. In addition to fishing, various water sports can be practiced on the reservoir.
power plant
The Castelo do Bode power plant is one of the medium-sized hydropower plants in Portugal with an installed capacity of 139 (or 159) MW . The average annual generation is 390 (or 361, 396.5 or 412) million kWh .
The three Francis turbines of the power plant each have a maximum output of 46 MW and the generators 57.4 MVA . The rated speed of the turbines is 214.3 / min. The generators have a nominal voltage of 15.5 kV . In the switchgear , the generator voltage is increased from 15.5 kV to 220 kV using power transformers.
The first two machines were put into operation in 1951, the third in 1952. They are located in a machine house at the foot of the dam. The turbines and the associated generators were supplied by Alsthom .
The minimum height of fall is 52.5 m, the maximum 95.8 m. The maximum flow rate is 80 m³ / s per turbine.
The power plant is owned by the CPPE but operated by EDP .
