Tâmega: one of the largest hydroelectric projects developed in Europe in the last 25 years
Iberdrola will add two wind farms to the Tâmega hydroelectric complex - one of the largest energy storage facilities in Europe, located in northern Portugal - making it one of the largest energy initiatives in the country`s history. The giga-battery, with an investment of more than €1.5 billion, will involve the construction of three dams and three power plants (Gouvães, Daivões and Alto Tâmega) with a combined capacity of 1,158 MW. And two wind farms with a combined capacity of 300 MW.

The three power plants will have an installed capacity totalling 1,158 MW, representing an increase of 6 % in the total installed electrical power in the country.
The complex will be capable of producing 1,766 GWh per year, enough to meet the energy needs of the neighbouring towns and the cities of Braga and Guimarães (440,000 homes). Furthermore, this large renewable infrastructure will have a storage capacity of 40 million kWh, equivalent to the energy consumed by 11 million people during 24 hours in their homes.
Tâmega will eliminate the end of 1.2 million tonnes of CO2 emissions annually and will diversify the generation sources, doing away with imports of over 160,000 tonnes of oil per year. It will also promote to the economic activity and the employment in the region, since it is estimated that during the entire construction phase 3,500 direct jobs and 10,000 indirect jobs will be generated — 20 % of them from neighbouring towns —through more than 100 providers— 75 of them from Portugal. Several hundred people will be hired in operational phase.
