The present invention concerns a method of operating a wind park having a plurality of wind power installations. A wind power installation includes an electrical energy storage means associated with the wind power installation to store electrical energy which is consumed for starting up the wind power installation after stoppage and consumed for emergency shutdown of the wind power installation. In some embodiments, the wind power installation includes a control system to control taking of energy from the electrical energy storage means for an emergency shutdown procedure such that a sufficient emergency shutdown reserve is maintained in the electrical energy storage means to start a first wind power installation without consuming energy from a network.
