The Foz Tua Hydroelectric is one of the priority projects of the National Programme of Dams with strong Hydroelectric Potential promoted by the Portuguese Government.

The AHFT project is located on the Terminal part of the river Tua and will include the dam, hydraulic, Central, substation, cutting station and reservoir.

The AHFT will be equipped with two reversible groups, enabling it to pump water from Régua reservoir to the dam of Tua, thus increasing the value of hydroelectric power.

Key features of hydroelectric.

  • Full Storage Level (SPL): 170
  • Maximum full level: 171
  • The maximum height of the dam: 107 m
  • Extension of the reservoir: 27 km
  • The total volume of the reservoir: 106 hm3
  • Power: 255 MW
  • The net annual production of 275 GWh
  • Quota of expropriation: 171
  • Total flooded area: 420 ha

The scope of intervention includes the following Environmental Monitoring, since prior to the construction phase, construction phase and phase of filling of the reservoir: Hydro systems Monitoring; Noise Monitoring; Monitoring of Spatial Planning and Land Use; Monitoring in the Scope of the National Programme of Dams with Hydroelectric High Potential; Climate Monitoring; Air Quality Monitoring; Monitoring of the Social Economy.
