A method for operating at least one wind turbine is provided, the wind turbine being electrically coupled to a power-to-gas converter and an electric grid, wherein a control unit determines a power level for the power generated by at least one generator of the at least one wind turbine and at least partially feeds the generated power to the power-to-gas converter when the determined power level reaches or exceeds a given lower threshold value, wherein the amount of power fed to the power-to-gas converter is kept constant when the determined power level reaches or exceeds a given upper threshold value.
