Abstract: A shaft power plant for generating electricity by energy conversion of an outflow between upper water and lower water in a river includes at least two power plant modules, each having a vertical shaft with an open top and a shaft crown forming an inflow plane. The inflow plane is substantially parallel with the river bed and extends below a water level of the upper water. Each of the power plant modules also has a turbine generator unit arranged in the shaft. The power plant also includes an ecological connecting channel formed as an outflow from the upper water into the lower water without generating electricity by energy conversion.

Abstract: A shaft power plant for energy conversion of a discharge between a headwater and a tailwater, comprising a vertical shaft, the top of which forms an inflow plane which is parallel to the bed and extends below the headwater water level, wherein the shaft is open toward the top and is closed by a base at its bottom end, a unit composed of a turbine and an electrical machine, wherein the unit is arranged entirely under water in the shaft and wherein the turbine is arranged for water to pass through vertically, and an outflow, which is connected to the turbine, represents a closed flow channel and leads through a through-passage in the shaft to the tailwater, wherein, in a horizontal plane of a turbine runner of the turbine, a first cross-sectional area of the shaft is much larger than a second cross-sectional area taken up by the turbine runner.
