Inscribed inside the National Plan of Preys of High Hydroelectric Potential, this prey will begin to operate in August of 2014, generating 170 MW of power and producing until 444 GWh to the year. For this, will have two preys, situated in the river Flavour to 9,5 kilometres of distance between yes, and that will flood the valley along more than 50 km, creating like this the third bigger lake of Portugal.

The secondary prey, of type gravity and situated waters down, more near of the desembocadura, will have a height of 45 m and a width of 315 m. In his construction work the five bigger cranes of the project. It treats of two 21LC750, with capacity of load of until 48 tonnes, and three 21LC550 with capacity of maximum load of 18 tonnes. Another 5LC5010 with maximum load of 5 tonnes serves of crane of service, helping to manage the machinery and necessary materials in the work.

Besides, two 21LC290 with maximum load of 18 tonnes work in the construction of a new bridge, of 268 metres of length and height of 40 metres. This bridge, situated very near of the head office of waters down, will allow to the road IN102 cross the river, since the current Put you give Portela will remain submerged by the waters.

Is foreseen that the new Hydroelectric Head office initiate his activity around the middle of 2014.
