Unveiling Europe’s biggest battery park

Schwerin, Germany-based green power utility WEMAG has ordered Europe’s first battery park for the commercial balancing of grid fluctuations, says Younicos, a Berlin company that will deliver the fully automated system. The battery park will hold up to 5MWh of energy and will be commissioned in mid-2014 to help keep the transmission network stable and integrate wind and solar power into the existing grid.

It uses lithium-ion cells manufactured by Samsung SDI, which will provide a 20-year guarantee on the performance of the cells. The battery park will finance itself by competing in the primary frequency regulation market.
