The present invention concerns a downwind power plant (1) with at tower (2), a machine housing (3) and a turbine (4) supported in the housing (3). The turbine (4) defines a plane of revolution and is adapted to be pivoted to a position substantially perpendicular to the direction of the wind. At least two wires (6) are connected to the tower (2) at its one end, and each wire is attached in at least one attachment point in the other end for maintaining the tower in an erected position during operation. Each wire may include at least a first and a second position. The wire in the first position extends at an oblique angle downwards from an attachment point in or close to the centre for the horizontal forces that are applied to the tower by the turbine under operation. In the second position is each wire lead out of the plane of revolution, such that the turbine plane is free to turn around a vertical axis without the wire impeding the turbine plane. Furthermore, it is described a method for operating a downwind
