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.

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.
