Iberdrola has launched one of its main projects in Portugal: a hydroelectric gigabattery, with three dams and three plants, with a capacity of almost 1,160 megawatts (MW). The company inaugurated this Monday the project located in the town of Tâmega, which has involved an investment of 1,500 million euros and whose construction has lasted eight years.

The hydroelectric mega-complex is located to the east of Porto and has been inaugurated by the Prime Minister of Portugal, António Costa, and the President of Iberdrola, Ignacio Sánchez Galán. The Tâmega gigabattery is considered the largest clean energy project developed in Portugal. It is made up of three reservoirs, with reversible pumping capacity, and three plants (Alto Tâmega, Daivões and Gouvães), which will mean a 6% increase in the installed capacity of the neighboring country.
Specifically, the Tâmega electro-producer system is capable of storing 40 million kWh, equivalent to the energy consumed by 11 million people in their homes for 24 hours, making it one of the largest energy storage systems in Europe.
This reversible pumping capacity means that it can store energy to be used, for example, at times of peak demand and will mean, as Iberdrola explained, avoiding the importation of more than 160,000 tons of oil per year.
Dialogue with the Portuguese Government
During the inauguration, the chairman of Iberdrola pointed out that the development of the Tâmega project has been possible thanks to the environment of legal stability and good dialogue achieved by the Government of Portugal in recent years. In addition, he has indicated that this infrastructure shows that the two great goals of Europe’s energy policy, energy independence and decarbonization, are perfectly compatible as long as work is done on the electrification of the economic and productive system.
Ignacio Sánchez Galán has also announced that the company will be able to double the investments made in the gigabattery in the coming years, reaching 3,000 million euros, which it will allocate to new wind farms and solar plants already under development or construction. From the outset, the future construction of two wind farms linked to the gigabattery will be added to the project.
Also present at the inauguration were the Minister for the Environment and Climate Action of Portugal, Duarte Cordeiro; the Secretary of State for the Environment and Energy, João Galamba; and the presidents of the Municipal Chambers of Ribeira de Pena, Vila Pouca de Aguilar, Boticas, Chaves, Montalegre and Cabeceiras de Basto.
