The Tâmega Hydroelectric Complex represents the largest hydropower project in the history of Portugal and is one of the European energy sector’s most important initiatives of the past 25 years.

Significant increase of national hydropower capacity

The Iberdrola Group has invested more than 1.5 billion Euros in constructing the Tâmega hydroelectric complex in northern Portugal. The project will involve building three dams and three power plants - Gouvães, Daivões and Alto Tâmega - with a combined capacity of 1,158 MW, which will represent an increase of 6% of the total installed electrical power in the country.

The consortium is led by the company Ferrovial Agroman, with participation from local company MSF, and was selected by Iberdrola Group to construct the Daivões dam and hydroelectric power plant. ORBINOX is the supplier of hydro-mechanical equipment for the bottom outlets.

The FCC Group, an international reference in environmental services, water and construction, has also entrusted ORBINOX with the supply of equipment for the Gouvães dam.

ORBINOX has already commissioned the valves and gates in two of the dams (Daivões and Gouvães). We were selected for this large-scale project thanks to an offer that is technically very solid, and at the same time economically competitive. Also, we have 30+ years of experience in the management of hydromechanical equipment projects.

Products supplied to date:

  • Bureau gates
  • Fixed cone valves
  • Bulkhead gates
  • Various safety and regulation valves in auxiliary equipment

Construction work on the Tamega River hydroelectric complex began in 2015. The Gouvães dam is expected to be operational in 2021, followed by Daivões dam in 2022 and Alto Tâmega dam in 2023.
