The turbine has a high efficiency factor in large parts of the adjustment range. In terms of operation, this aggregate is therefore used for regulation, while the old turbines in Rånåsfoss I are run at a fixed load, giving the best total efficiency factor for the installation as a whole.
Expansion of the existing dam
In addition to the control gates at Rånåfoss I, a new log flume was built, with a hinged hatch measuring 8 x 2.6 meters. A fish ladder was also constructed alongside the log flume.
