The present invention refers to an arrangement (“A”) related to a body of water for creating conditions for generating electric power from a prevailing force of wind (“W”).Utilized pontoon units are made up of and associated with at least two vertical, or at least essentially vertical, posts, which may float, for forming a frame portion and at least one upright stabilizing the position of the frame portion in the body of water.More particularly, the invention indicates that between an upright and each one of the two posts, a first post and a second post, there extends a bar-shaped means dimensioned for taking up a compressive force, and that between said upright and each one of the first and second posts there extends at least one first means dimensioned for taking up a tractive force and at least one second means dimensioned for taking up a tractive force.
