w Energy Storage System for Tâmega River The Tâmega River flows from its source in Spain, through to Portugal where it discharges into the Atlantic Ocean. Along the way it passes through ancient settlements, but also through deep narrows between mountains ideal for dams. A new energy storage system is commissioning in the Portuguese mountains, with capacity equivalent to a mega battery. The New Tâmega Energy Storage System The Portuguese government approved a new energy storage system comprising three new hydroelectric schemes along the Tâmega River in 2014. The first of these, namely the Alto Tâmega concrete double curvature arch dam, has begun generating electricity. Wikipedia confirms the following statistics: The electrical heart of the pioneering Alto Tâmega dam, comprises two 80 megawatt turbine generating units. Their maximum flow rate is 200 cubic meters-a-second, producing 139-gigawatt-hours of electricity a year. Two lateral spillways with total discharge capacity of 1,825 cubic-meters-a-second, prevent the dam over-flowing. More Information About Alto Tâmega Dam The Financial Times published more information ‘on the ground, after contributor Barney Jopson investigated the site. He describes the sound of the 230-ton water pump as a ‘roaring hum’, as it sends water four miles up the mountain to a ‘water battery, where the energy stores. The new energy storage system at Tâmega high up in the Portuguese mountains takes surplus energy from the grid. And then uses this resource to lift the water to a smaller dam higher. And then, when the grid is hungry during peak, it release the energy to the pumps-become generators, so it becomes electricity again. This energy is enough to charge 400,000 electric vehicle batteries, or sustain 2.4 million homes for a full day according to Financial Times.
