The new, state-of-the-art power plant will replace the old plant, which was built in the 1930s and which was owned by the municipality of Rheinwald. The new power plant will increase the production of renewable, domestic energy by a factor of almost six. Energy production will increase from 1.1 million kWh to around 6.1 million kWh per year, which corresponds to the average annual consumption of approximately 1500 households.

The new plant thus achieves a substantial increase in output and production and is fully in line with the Swiss federal government's Energy Strategy 2050. Hydropower is Switzerland's most important renewable energy resource. Its potential should be harnessed as optimally as possible - among other things with the considerable expansion of existing plants, as has now been achieved at the Hüscherabach. The small hydropower plant with a high head of water (238 metres) uses the Hüscherabach stream, which flows into the Hinterrhein river near Splügen. The high-pressure plant consists of a water catchment, a 2,240-metre penstock and the power station, which houses a 1.95 MW Pelton turbine. In spite of the challenges posed by the Covid pandemic, the construction work took only 16 months. Local companies also played a part in the construction process.
