New project: 10 MW large-scale battery storage facility in Ettringen

green flexibility is setting another milestone for the energy transition with a new battery storage project in Unterallgäu. A 10 MW battery storage facility with a capacity of 25 MWh is being built in Ettringen in the area of the grid operator Lechwerke Verteilnetz (LVN). Commissioning is planned for the end of 2025.

With the increasing amount of photovoltaic and wind power being fed into the grid, there is a growing need for flexible storage solutions that can absorb surplus electricity on a large scale and release it again when required. The battery storage system in Ettringen fulfils this task precisely by reducing peak loads and contributing to the stability of the regional grid. It stores surplus electricity from renewable energies and can feed it into the grid in a targeted manner, thereby increasing the flexibility of the power grid.

An innovative approach for greater grid stability

In addition to these conventional areas of application for battery storage systems, an additional grid-neutral use in the regional electricity grid was agreed for this project. This ensures that the storage system not only reacts to signals from the national market but also makes a targeted contribution to stabilizing the local grid infrastructure.

The project in Ettringen is another example of the green flexibility strategy: implementing innovative, grid-supporting storage solutions at the right locations. And that in partnership with the local grid operators.

With the start of construction in the coming months and the planned commissioning by the end of 2025, the project will make an important contribution to a secure and sustainable energy supply in the region.

"When green flexibility contacted me almost a year ago, it was immediately clear to me that this approach was the right way forward for the energy transition. Instead of exclusively driving forward the expansion of renewable energies, green flexibility focuses specifically on storing this energy - an essential building block for a sustainable energy future. The municipality of Ettringen wanted to make its contribution to precisely this. The municipal council unanimously supported this project. I wish the project all the best and continued success." – Robert Sturm, Mayor of the municipality of Ettringen. 

"We are delighted to prove once again with this project that battery storage systems are not only an economical solution for the energy transition, but also one that supports the grid. The excellent cooperation with LVN shows how intelligent storage solutions can relieve the burden on regional grids and make optimum use of renewable energies." – Christoph Lienert, Co-Founder and Managing Director of green flexibility.
