Berlin-based energy storage software firm Younicos and German utility WEMAG have started work on expanding the storage capacity of a battery park in Schwerin, Germany, from 5MW to 10MW power output and 5MWh to 14.5MWh capacity.

Younicos is providing software for plant control as well technical expertise during the implementation phase. It will also integrate more power electronics into the project.

WEMAG aims to complete the building in March next year and commission the second power plant block in June 2017.

The Schwerin battery park, which acts on the region’s frequency regulation market, was commissioned in 2014 as the first commercial battery storage resource in Europe, claims Younicos.

Alexander Schönfeldt, Younicos vice president of sales for EMEA, said: “The fact that WEMAG is now investing €5 million in order to increase the available power and energy for system service is a strong testament to the commercial success and performance of battery storage in Europe.”

Christian Pegel, minister for energy, infrastructure and land development of Mecklenburg-Vorpommern, said: “Especially with regard to the expansion of renewable energies and the future shutdown of old power plants, it is necessary to invest in technologies to ensure the quality of supply and grid stability. The battery park in Schwerin was a pioneer of this development and has impressively shown that new technologies are more than capable of providing system services in the future.”
