The present invention provides an improved arrangement for supplying emergency power to a wind power installation. In the event of a power failure, sufficient emergency power may be supplied to reposition the rotor blades of the wind power installation and avoid damage to the overall system. This is done through the use of one or more capacitors. The capacitors may be charged with energy during the normal operation of the wind power installation and, in the event of a system failure, the energy stored within the capacitors may be used to provide emergency functions. In addition to repositioning the rotor blades, the stored energy may be used, for example, to rotate the wind power installation pod away from the wind and power emergency or auxiliary lighting systems.
