Siemens Smart Infrastructure and Zukunftsenergie Nordostbayern GmbH (ZENOB) have signed a letter of intent in Wunsiedel for the turnkey construction of a 100-MW battery storage facility in the German town.

The plant, with a storage capacity of 200 MWh, is intended to use surplus renewable energy and cover demand peaks in the power grid. The 5000-sq-m energy storage facility is capable of supplying 20,000 average households with electricity. The lithium-ion battery storage system will be provided by Fluence, a joint venture between Siemens and AES. Siemens will handle project management, including a technical implementation concept, as well as the construction of a medium-voltage switchgear system and connection to the high-voltage grid. Among other things, the letter of intent also includes the development of a financing concept.

"Electricity storage facilities are an important building block for shaping the future of energy," said Marco Krasser, managing director of SWW Wunsiedel GmbH, one of the partners in ZENOB. "They can help stabilize the grid and make better use of energy generated from renewable sources. They draw surplus power from the grid and feed it back when electricity demand is higher. Smart storage technology will increase the local and national supply of green power. That is why we are gradually expanding the capacity."

The planned storage system from Fluence will be able to store and release large amounts of green power. This will allow the more flexible use of clean energy beyond the hours of production, including during periods of expensive peak load.
