Alterric has put its first battery storage system into operation at the Oslebshausen wind farm near Bremen. After a successful test phase, the plant is now feeding electricity into the grid. With the project, the company is expanding its activities beyond pure power generation and further positioning itself as a system player.
The battery storage system has a capacity of two megawatts and can absorb electricity from the wind farm in a targeted manner and feed it back into the grid with a time delay. This makes it possible to stabilize the feed-in and better adapt it to the demand in the grid. At the same time, the system can react to grid requirements within a very short time and thus contribute to the stability of the power system.
“We are making targeted investments in storage technologies because flexibility is the basis for a stable and efficient energy system and we are thus also relieving the grids that are currently under massive load,” says Dr. Frank May, CEO of Alterric. “But it is also clear that flexible solutions on the producer side are no substitute for investments in the intelligent expansion of the grids. Considerable efforts are still needed here to leverage the enormous potential of the energy transition for Germany as a business location.”
With the project in Oslebshausen, Alterric is starting the construction of so-called energy parks. Existing wind farms will be supplemented with storage systems and combined with other technologies in the future in order to combine generation and flexibility at one location. Building on this approach, the company is also expanding its capabilities in system operation: Alterric is already active in the market for balancing power and also provides reactive power to stabilize the grids.
Alterric is consistently pushing ahead with the expansion of its storage portfolio. Six more battery storage systems with a total capacity of over 100 megawatt hours are being implemented, two of which are already under construction.
With the first storage system in grid operation and further projects in preparation, Alterric is further expanding its role in the energy system. The aim is to make renewable generation more predictable and to support a stable, competitive energy supply.
Dr. Frank May will also address these topics at the BDEW Congress in Berlin. There he will take part in the panel discussion “Battery storage: From market trend to system component” on Thursday, June 11, 2026.
