A gargantuan battery storage system has joined the ranks in Germany. Housed in a quaint corner of Bollingstedt, Schleswig-Holstein, this beastly powerhouse stows surplus energy harvested from wind and solar power to regurgitate it onto the grid during power-hungry hours.
Capable of servicing approximately 170,000 households for two hours straight, this titanic system boasts a capacity of 103.5 megawatts (MW) and a storage capacity of 238 megawatt-hours (MWh).
Storing and Shifting the Surplus Solar Power:
Roused by the German-Norwegian specialists, Eco Stor, and EPW GmbH, the system is a concoction of 64 lithium-ion battery-laden containers and 32 containers harboring inverters and transformers. Tobias Goldschmidt, Schleswig-Holstein's Minister for Energy Transition, extols the system's multi-purpose nature, saying, "These energy stores are the jack-of-all-trades: They handle the erratic fluctuations in solar and wind energy, shore up the grids, reduce electricity prices, and bolster the green energy quotient in the power networks."
Georg Gallmetzer, Eco-Stor CEO, supports, "With our technology, we can transport valuable solar power from daylight hours to the evening, tamp down prices, and significantly lessen the usage of gas and coal." Other large-scale storage systems are in the pipeline, with other companies jumping on the bandwagon.
As of now, the corporate storage solutions in Germany aggregate to a capacity of 2.7 gigawatt-hours (GWh), according to RWTH Aachen's Battery Charts. When residential solutions are factored in, the figure balloons to 20.3 GWh, with a substantial 16.7 GWh deposited in residential storage.
As Germany marches towards its renewable energy ambitions, storage capacity expansion plays a pivotal role in integrating volatile energy sources like wind and solar power.
While you're here, did you know that Eco Stor is planning two more projects identical to the one in Bollingstedt? The second one is a 103.5 MW/238 MWh project in Schuby, also in Schleswig-Holstein. Moreover, Eco Stor has a series of larger projects underway, with capacities of 300 MW/600 MWh 1! Additionally, Green Flexibility and Enertrag are planning a 60 MW/130 MWh battery storage system in Tantow, Brandenburg, with construction set to commence soon and commissioning planned for early 2026 5. These initiatives solidify Germany's dedication to enhancing its battery storage capacity to meet its renewable energy objectives.
- The community in Schleswig-Holstein, particularly Bollingstedt, is set to benefit from environmental-science and technology advancements as Eco Stor plans two more identical vocational training projects, aiming to boost renewable energy storage.
- As Germany strengthens its commitment to renewable energy, the involvement of industries such as finance and energy is crucial, with corporations like Eco Stor and Green Flexibility planning larger-scale vocational training projects for battery storage systems.
- The expansion of battery storage systems, including the second 103.5 MW/238 MWh project in Schuby and the 60 MW/130 MWh system in Tantow, signifies the integration of vocational training in science and technology to address the erratic fluctuations in renewable energy sources, such as wind and solar power.
