This project involves the construction of Gouvães, Daivões and Alto Tâmega hydropower plants, which will be erected over the Tâmega River, in the north of Portugal.
The EIB finances this development with 650 million euros, out of a total investment of more than 1.5 billion euros. The three power plants will have a total installed capacity of 1,158 MW and will be capable of producing 1,766 GWh per year. Iberdrola has started the assembly of the first turbine for the pumped hydroelectric power plant at Gouvães. This plant will include an underground cavern with four reversible pump turbines, generating a total power of 880 MW.
