Multi-level energy storage system for energy from hydropower
In Schlins, Vorarlberg, a pioneering and environmentally friendly project was realized that includes a multi-level energy storage system. This efficiently and sustainably supplies a business park with energy from a small hydropower plant. This innovative power plant can provide an output of around 70 kW. This capacity is sufficient to cover the base load of the business park. By reusing existing resources, this project not only contributes to a sustainable energy supply, but also sets an important example in terms of environmental protection and resource efficiency.

Small hydropower plant meets innovative battery storage system
Initially, the power plant faced challenges in coping with peak loads, which led to increased costs. To solve this problem, a stand-alone battery storage system with a capacity of 260 kWh and an output of 67.5 kW was installed. This storage system not only offers an efficient solution for peak loads, but also serves as a backup system. In the event of maintenance work or a short-term outage of the hydropower plant, the battery storage system can supply the business park with electricity for several hours or support grid power.
At night, the storage facility can be fully charged using surplus energy from the small hydropower plant in order to provide additional energy during the day for peak load capping.
Project details:
- Storage capacity: 261 kWh (208 kWh usable)
- Extension: Can be extended as required
- Location: Schlins, Austria
- Monitoring: cell voltage, cell temperature, current and passive balancing
- Purpose: Optimization of self-consumption, base load supply with energy from the small hydropower plant, peak load capping
- Degree of self-sufficiency: ~1 day
Furthermore, this project is an excellent example of how innovative energy solutions can help optimize energy efficiency and reduce operating costs. It impressively demonstrates the benefits of second-life ESS in a commercial environment and highlights the importance of sustainable energy sources in modern industry.
All-in complete system
The container is fitted with the individual modules on site at e.battery systems. The container is delivered fully equipped with battery modules. The power storage unit is positioned and electrically installed on site in Sennwald.
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 systems 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 preferably via alternative power sources, such as electricity from photovoltaics, and then used again as required.
But why do we actually want to store energy? By storing energy, we can generate power independently of the grid and therefore have access to this energy even in the event of an outage. We can also optimize our own energy consumption by capping peak loads.
The complete control and monitoring of energy consumption, energy sources and the energy storage system works simply via our energy management system.
