Storage specialist Eco Stor continues to make progress on its major project in Schuby, in Germany’s state of Schleswig-Holstein. The Norddeutsche Landesbank (NORD/LB) announced today that it has arranged the financing package for the BESS which boasts a power output of 103.5 MW and a capacity of 238 MWh.

The Schuby facility is considered a “twin” to an operational 103.5 / 238 MWh plant in nearby Bollingstedt which went live in early June, 2025. Spanning approximately 1.2 hectares, the Schuby site will house 64 lithium-ion battery containers and 31 inverters. A critical component was already installed in August 202 with: a 130-ton high-voltage transformer designed to step down electricity from the 110 kV grid level.

Commercial maturity without subsidies

The secured financing highlights the growing bankability of large-scale storage in Germany. “The successful financing of the project in Schuby demonstrates that large-scale battery storage systems in Germany have now reached a level of commercial maturity that enables their development with private capital and without government subsidies,” stated Jörn Rohland, CFO of Eco Stor.

“Despite ongoing regulatory uncertainties, the market already offers reliable revenue mechanisms and robust structures. By starting construction early, we were able to accelerate implementation and secure the grid connection. This allows us to provide the urgently needed flexibility to the energy system from mid-2026 onward.”

A crucial factor in the financing structure is a tolling agreement signed in November 2025 with Swiss energy group Alpiq. This five-year contract guarantees the German-Norwegian storage firm with fixed revenues, while Alpiq secures exclusive rights to market the flexibility on spot and intraday markets.

The plant in Shuby is scheduled to go online in mid-2026.

Opinion & Analysis

Falling li-ion battery prices mirror solar photovoltaics trends: Is there a role for second-life batteries before recycling? Lithium-ion batteries are everywhere, powering everything from consumer electronics to electric vehicles, residential PV storage systems, and, more recently, mitigating curtailment in large-scale wind and solar power plants. EVs are driving large-scale demand for Li-ion batteries which will result in substantial volumes of spent batteries in the near future. This scenario highlights the potential for repurposing EV batteries for second-life stationary applications, which could maximise their value before recycling. However, to fully realise this opportunity, several economic, technical, and regulatory challenges must be addressed and resolved.

Opinion & Analysis

When will there be nationwide financing solutions for battery storage systems in Germany? The use of battery storage systems is essential for the success of the energy transition and the best possible use of renewable energies, but also for being able to temporarily store surplus energy from other sources. Technically, there are already solutions for all possible sizes of battery storage systems, from private home storage systems to large-scale storage systems with a capacity of more than 50 MWh. But what about the financing of battery storage systems, is it already offered as standard?
