A wind installation comprising a wind turbine (1) and an airborne wind energy system (12, 13), e.g. in the form of a kite (12) or a glider (13) is disclosed. The wind turbine (1) is electrically connected to the power grid via a power transmission line (27). The wind installation further comprises an airborne wind energy system (12, 13), e.g. in the form of a kite (12) or a glider (13), for generating electrical energy. The airborne wind energy system (12, 13) comprising a separate generator is coupled to the wind turbine (1) via a cable (6) and the separate generator is electrically connected to the power transmission line (27).
