The need to ensure that renewable energy resources can meet basic electricity demand is stepping up the race for giant battery storage systems across Europe.

Siemens Smart Infrastructure and German grid operator Zukunftsenergie Nordostbayern GmbH are the latest companies to join the race to improve battery storage, with plans to develop a 100 MW lithium-ion battery storage facility in the city of Wunsiedel.

The battery will be able to power 20,000 average German homes when completed by supplying them with electricity produced from renewable energy resources for use during peak demand periods.

Fluence, a joint venture of Siemens and AES, will supply the batteries for the project which will be built on a 5,000 square meter site.

Siemens will be responsible for the management of the project, including a technical implementation concept, as well as the construction of a medium voltage switching system and connection to the high voltage grid. Siemens and Zukunftsenergie Nordostbayern GmbH will also work together to develop a financing concept.

Marco Krasser, Managing Director of SWW Wunsiedel GmbH, one of the partners of Zukunftsenergie Nordostbayern GmbH, said: “Electricity storage facilities are an important element in shaping the future of energy.

“They can help stabilize the grid and make better use of energy produced from renewable sources. They take the surplus electricity from the grid and reinject it when the demand for electricity is higher. Smart storage technology will increase local and national supply of green energy. That is why we are gradually increasing the capacity.

Bernd Koch, Head of Technology Performance Services at Siemens Smart Infrastructure Germany, adds: “This also benefits the upstream grid operator as it gives them more flexibility to compensate for voltage fluctuations, which are increasingly common due to expansion of renewable energy production.

Siemens project manager Andreas Schmuderer reiterates: “For the network operator, the solution promises significant relief. Switching on and off large industrial plants in the network area requires a lot of electricity.

“Until now, the grid operator has had to maintain considerable reserves. If these can be eliminated in the future, there will be great potential for reducing CO2 emissions in the local energy market.
