The Torrejón dam is the name given to two dams with a shared hydroelectric power station in the province of Cáceres , Spain , near the mouth of the Tiétar and the Tagus . The dam Torrejón Tajo ( Spanish Presa de Torrejón Tajo ) is located in the municipalities of Toril and Torrejón el Rubio ; it damms the Tagus into a reservoir. About 200 m from it is the Torrejón Tiétar dam ( Presa de Torrejón Tiétar in Spanish ) in the municipalities of Toril and Serradilla ; it dams the Tiétar about 2 km before its confluence with the Tagus. The two dams are used to generate electricity. They were completed in 1966. The dams are owned and operated by Iberdrola Generacion SA .

Torrejón Tajo

Barrier structure

The barrier structure is a concrete gravity dam with a height of 62 m above the foundation base . The top of the wall is at a height of 247 m above sea level . The length of the top of the wall is 300 m. The volume of the dam is 248,000 m³.

The dam wall has both a bottom outlet and a flood relief . A maximum of 200 (or 224) m³ / s can be discharged via the bottom outlet, and a maximum of 5600 m³ / s via the flood discharge. The design flood is 5070 m³ / s.

Reservoir

With the normal storage target of 243 (or 243.5 or 244) m, the reservoir extends over an area of ​​around 9.8 (or 10.41) km² and holds 166 (or 176 or 188) million m³ of water.

Torrejón Tiétar

Barrier structure

The barrier structure is a concrete gravity dam with a height of 34 m above the foundation base. The top of the wall is at a height of 224 m above sea level. The length of the top of the wall is 227 (or 230) m. The volume of the dam is 75,000 (or 80,000) m³.

The dam wall has both a bottom outlet and a flood relief. A maximum of 970 (or 1300) m³ / s can be discharged via the bottom outlet, and a maximum of 3000 (or 3140) m³ / s via the flood discharge. The design flood is 2668 m³ / s.

Reservoir

With the normal storage target of 222 (or 223) m, the reservoir extends over an area of ​​around 2.19 (or 2.94) km² and holds 18 (or 22) million m³ of water; 12 million m³ of this can be used to generate electricity.

power plant

The installed capacity of the power plant is 129 (or 132 or 196) MW . When the actual output of the four machines was checked on March 14, 2001, values ​​between 15.94 and 16.67 MW were determined; with optimal height of fall and optimum flow rate the performance of the machine is 32.1 to 33 MW. The drop height is 48 m; the maximum flow rate is 328 m³ / s. The machine house is located on the right side of the river Tajo between the two dams.

The power plant can be operated as a pumped storage power plant; in pumping operation the power consumption is 65 MW. The reservoir on the Tajo serves as the upper basin and the reservoir at the Tiétar as the lower basin.

Misfortune during the construction period

During the construction of the dams, on October 22, 1965, a dam broke , in which numerous workers died.
