Press releases

Ferrovial Agroman Dam

  • The arch-gravity dam will be 77.5 metres high and 264 metres long.

  • Ferrovial is building the penstock for the Gouvaes plant in Portugal for Iberdrola.

  • The work will take 56.5 months.

The consortium headed by Ferrovial Agroman, of which local company MSF is also a member, has been selected by Iberdrola to build the Daivoes dam and hydroelectric plant on the Támega river, in northern Portugal. The project will cost over 90 million euro and is to be completed in 56 and a half months.

It comprises construction of a concrete arch-gravity dam 77.5 metres high and 264 metres long, together with a power plant housing two turbines with a total installed capacity of 118 MW. Ferrovial will also build a 388-metre tunnel to divert the river, and a weir 71 metres long and 10.5 metres high, located 2.2 kilometres downstream of the dam.

Daivoes is the first of four main contracts to be awarded by Iberdrola as part of the Támega river hydroelectric project and is the second to be executed by Ferrovial Agroman for the utility in Portugal in the last two years, following participation in building the penstock for the Gouvaes hydroelectric plant and the inspection galleries in the Alto Támega dam.

Ferrovial Agroman has extensive experience in projects of this type around the world. Ferrovial's construction subsidiary is currently building the Los Cóndores hydroelectric plant in Chile, and it built the tunnels for the Ituango hydroelectric plant in Colombia.
