Dam
Belver Dam is a 30-metre-tall (98 ft) (height above foundation) and 327.5-metre-long (1,074 ft) gravity dam with a crest altitude of 47.5 metres (156 ft). The volume of the dam is 90,000 m³. The spillway is part of the dam body (10 roller gates with a maximum discharge capacity of 18,000 m³/s).
Reservoir
At full reservoir level of 46.15 metres (151.4 ft) (maximum flood level of 47.15 metres (154.7 ft)) the reservoir of the dam has a surface area of 2.86 km² and its total capacity is 12.5 mio. m³. The active capacity is 8.5 (7.5) mio. m³. Minimum operating level is 41 metres (135 ft).
Power plant
The run-of-the-river hydroelectric power plant went operational in 1951. It is operated by EDP. The plant has a nameplate capacity of 80.7 (80) MW. Its average annual generation is 220 (176, 180 or 239) GWh.
The power station contains six Kaplan turbine-generators in a dam powerhouse. The machines 1 to 5 have vertical shafts, whereas machine 6 has a horizontal shaft. The maximum hydraulic head is 15.2 metres (50 ft).
