In Schlins, Vorarlberg, a forward-thinking and environmentally friendly project has been realized, which includes a second-life energy storage system. A business park is efficiently and sustainably supplied with energy from a small hydroelectric power plant. This innovative plant can provide a capacity of about 70 kW, which is sufficient to cover the base load of the business park. By reusing existing resources, this project contributes not only to sustainable energy supply but also sets an important example in terms of environmental protection and resource efficiency.

Small hydropower plant meets innovative battery storage

Initially, the power plant faced challenges in managing peak loads, leading to increased costs. To solve this problem, a standalone battery storage system with a capacity of 260 kWh and a power output of 67.5 kW was installed. This storage not only provides an efficient solution for peak loads but also serves as a backup system. During maintenance or a temporary outage of the hydropower plant, the battery storage can supply power to the business park for several hours or support the grid.

At night, the storage can be fully charged using excess energy provided by the small hydropower plant, enabling it to supply additional energy for peak load shaving during the day.

Projekt Details:

→ Speichergröße: 261 kWh (208 kWh nutzbar)

→ Erweiterung: Beliebig erweiterbar

→ Batterienabieter: Mercedes Benz

→ Standort: Schlins, Österreich

→ Überwachung: Zellspannung, Zelltemperatur, Strom und passives Balancing

→ Zweck: Optimierung des Eigenverbrauch, Grundlastversorgung durch Energie aus dem Kleinwasserkraftwerk, Lastspitzenkappung

→ Autarkiegrad: ~1 Tag
Furthermore, this project is an excellent example of how innovative energy solutions can contribute to optimizing energy efficiency and reducing operating costs. It impressively demonstrates the benefits of second-life energy storage systems (ESS) in a commercial setting and underscores the importance of sustainable energy sources in modern industry.

All-in-one system

The container is equipped with the individual modules on site at e.battery systems. The container is delivered fully equipped with battery modules. On-site in Sennwald, the electricity storage system is positioned and electrically installed.

The system is based on a 67.5 kW inverter. Additional power can be added by expanding the system with additional modules and containers.

The storage of the future

Energy storage or better known as Energy Storage Systems are the future of efficient energy storage and energy supply. Basically, the system is simple and quickly explained. Energy can be stored via the power grid or through alternative power sources such as electricity from photovoltaics to be used again as needed.

But why do we want to store energy? We can generate grid-independent power supply through energy storage and thus also fall back on this energy in the event of an outage. In addition, we can optimize our own energy consumption through so-called peak load capping.

The complete control and verification of energy consumption, energy sources and energy storage system simply works through our energy management system.
