EXPANDED WEMAG BATTERY PARK GOES ONLINE

July 14, 2017

Schwerin, Germany



Europe’s first commercial battery storage plant triples its size from 5 to 15 MWh

 

The second phase of a battery park owned by North German regional energy supplier WEMAG, Schwerin 2, has begun operation. Leading energy storage solutions provider Younicos engineered and deployed the first plant for WEMAG. The expanded energy storage facility has 10 megawatts (MW) and 15 megawatt hours (MWh) of capacity – WEMAG’s first battery plant, which was commissioned in 2014, had 5 MW/5MWh.

 

Younicos provided the control software for Schwerin 2, enabling the battery storage unit to participate in the primary frequency control market. In addition, the Berlin- and Austin-based energy storage pioneer provided WEMAG with technical expertise in implementation and managed the integration of additional power electronics.

 

“The pioneering energy storage facility we designed and developed at Schwerin 1 was the first commercial battery storage system in Europe,” said Stephen L. Prince, CEO of Younicos. “We are delighted to be able to continue the success story of this unique project together with WEMAG. The project impressively demonstrates the commercial success of storage in Germany and shows that the technology has become the fourth pillar of the energy industry.”

 

“Together with our partner Younicos, we integrated two different battery types under one roof, which was particularly challenging from the point of view of cooling and the greatly increased capacity of new batteries,” explained Tobias Struck, Managing Director of Batteriespeicher Schwerin GmbH & Co. KG, who is responsible for storage projects at WEMAG.

 

The WEMAG storage facility in Schwerin is Europe’s largest hybrid lithium-ion battery network. The 10 MW of power in Phase 2 comprise a network of 53,444 lithium-ion batteries in 215 battery cabinets, 18 inverters, nine transformers and a medium-voltage system. Its main function is to stabilize electricity supply, especially when renewable energy sources fluctuate. In addition, the battery park can help to restart the grid after major disruptions, so that damage can be avoided.

 

Against this background, an innovative black start concept known as “Kickstarter” is currently being brought to the market. It is supported by a consortium consisting of Energieversorgung Schwerin GmbH & Co. Generation KG, the Chair for Electrical Power Supply at the University of Rostock, WEMAG AG and Younicos, and sponsored by the funding initiative “Zukunftsfähige Stromnetze” of the Federal Ministry of Economics.
