We commissioned the small hydropower plant at the Brajčino site in May 2014. Offering an annual electrical output of around 5.0 GWh (long-term average), the facility currently supplies power to some 1,200 households. Difficult ground conditions in the water catchment area were discovered in good time during the construction phase, and the necessary blasting work was duly carried out. The height difference between the Brajčino turbine house and the water catchments located above it measures 115 metres, giving a pressure in the filled penstock of 11.3 bar. The pelton impeller spoons are therefore impacted by water jets impinging at the speeds of around 46 metres per second (approx. 166 km/h), generating turbine speeds of 500 rpm to drive the generator and produce electricity.
