Spanish utility Iberdrola has inaugurated its ‘Tâmega Gigabattery’ in northern Portugal, a renewable energy complex including pumped hydro with an energy storage capacity of 40GWh.
Iberdrola has invested €1.5 billion (US$1.54 billion) in the facility which combines two run-of-river hydroelectric plants and an 880MW PHES unit (Gouvães), with a total combined hydroelectric power of 1,158MW. That will increase the electrical power capacity on the Portuguese grid by 6%.
The Tâmega electrical power production system can store 40GWh (40 million kWh), which makes it one of the largest energy storage systems in Europe.
