1. A method of installing a wind turbine at an offshore location, the wind turbine including a wind turbine tower and an energy generating unit, the wind turbine tower is configured to be secured to a transition piece at the offshore location, the method comprising:
prior to shipping the wind turbine tower and the energy generating unit to the offshore location, electrically coupling one or more electrical devices and/or systems by one or more cables to:
electrical equipment in the energy generating unit;
electrical equipment in the wind turbine tower; or
a test dummy,
wherein the one or more electrical devices and/or systems are configured to be attached to the transition piece once the wind turbine tower is secured to the transition piece;
testing and commissioning the one or more electrical devices and/or systems while electrically coupled to the one or more cables; and
prior to shipping and after testing and commissioning, storing the one or more electrical devices and/or systems and the attached one or more cables inside the wind turbine tower.
