The Carrapatelo power plant ( Portuguese Barragem do Carrapatelo ) is a run-of-river power plant on the Douro . It is located in the Northern Portugal region in the Porto District . The Douro forms the border between the districts of Porto and Viseu at this point . The nearest town, Marco de Canaveses, is about ten kilometers north of the dam.

The project to build the power plant began in 1964. It went into operation in 1971. The power plant is owned by Companhia Portuguesa de Produção de Electricidade (CPPE), but operated by Energias de Portugal (EDP).

Barrier structure

The barrier structure is a concrete gravity dam with a height of 57 m above the foundation base . The top of the wall is at a height of 55 m above sea level . It is 400 (450) m long. The volume of the structure is 190,000 m³.

The dam is divided into a machine house on the left side of the river and then a weir system with six gates and a lock on the right side. The dam also has a bottom outlet . The design flood is 22,000 m³ / s; the probability of this event occurring has been determined to be once every 1,000 years.

Reservoir

With a normal storage target of 46.5 m, the reservoir extends over an area of around 9.52 km² and holds 148.4 (or 140) million m³ of water - of which 9 (or 15.6 or 16) million can be used. m³ can be used to generate electricity.

power plant

With an installed capacity of 201 (or 180) MW, the Carrapatelo power plant is one of the medium-sized hydropower plants in Portugal. The average annual generation is 870.6 (or 783, 806.1 or 882) million kWh / a. It is used to cover medium and peak loads .

The first two machines were commissioned in 1971, the third in 1972. The Kaplan turbines of the machines were supplied by Kvaerner Turbin AB , the generators by BBC . The turbines each have a maximum output of 63.4 MW and the generators 67 MVA . The nominal speed of the turbines is 115.4 min ⁻¹ . The generators have a nominal voltage of 10 kV . In the switchgear , the generator voltage of 10 kV is increased to 235 kV using power transformers.

The minimum height of fall is 20 m, the maximum 37 m. The maximum flow rate ( expansion water volume ) is 290 m³ / s per turbine.

lock

The lock on the right side of the dam can accommodate ships with a length of 83 m, a width of 11.40 m and a draft of 3.80 m. With a height of 35 m, it is one of the highest locks in the world. (see also locks on the Douro )
