Mini Hydro - A Comprehensive Solution for Smaller Sites

Application Range

The Mini Hydro Application Range of single units covers a range from 50 to 1,200 kW. By parallel operation, the output of the power plant can be multiple megawatts. Our portfolio provides solutions from very low heads like StreamDiver to high heads with 200 m and more for example eQ Pelton. Standard low voltage generators and electrical protection and control equipment is an integrated part of the Mini Hydro product line.
