It consists of a three-field weir system, the powerhouse with 3 sets of machinery and a 110 kV outdoor switchgear. Each of the three machine sets consists of a Kaplan turbine with vertical shaft and a shield generator.   Together, they have a total bottleneck capacity of 35.1 MW. The electricity generated is fed into the grid via a 110 kV outdoor switchgear.
