A hydro power plant in Germany is using lithium-ion battery power to help it stabilise its grid frequency.
The 3MW battery system by German lithium-ion storage system manufacturer ads-tec is using a battery to regulate fluctuations in grid frequency at the hydro power plant in Dörverden.
The system will allow the area’s utility firm to keep the frequency at, or very close to, 50 Hz in what is referred to as primary balancing power.
Increasingly more utility firms are turning to large-scale battery storage as a means to balance the grid frequency because they are more flexible and more dynamic than fossil fuel plants.
The adoption of batteries is set to rise as more renewable energy comes on line, and with it the need for fast charge and dis-charge storage to cope with energy fluctuations.
