Hydro Review reports that Iberdrola has synchronised the first turbine-generator unit at the 880 MW Gouvães pumped storage hydroelectric plant. The initiative, in collaboration with the Portuguese administration, will deliver clean power to the grid.
The Tâmega complex is one of Europe’s largest energy storage facilities, with an investment of more than €1.5 billion ($1.7 billion). It comprises three reservoirs (Gouvães, Daivões and Alto Tâmega) and three hydroelectric power plants with 1,158 MW of capacity on the Tâmega river, a tributary of the Douro.
Iberdrola announced that after eight years of construction work, the Gouvães and Daivões plants have now been completed and all of the generating units are undergoing commissioning tests.
