A method of erecting a wind turbine tower on a base, the wind turbine tower configured to be tethered by a plurality of cables and configured to support a wind turbine nacelle and a rotor, each of the plurality of tethering cables configured to extend between a first end attached to an attachment element on the tower and a second end attached to an anchoring element on an anchor block spaced from the base, the method comprising:

• attaching the first end of the plurality of tethering cables to an attachment element of the tower,
• detachably fastening a motorized winch on an anchor block, the winch comprising a wire on a spool,
• connecting the wire of the winch to the second end of one or more of the plurality of tethering cables,
• winding up the wire of the winch pulling the second end of the one or more of the plurality of tethering cables towards the anchor block and into position for fastening the second end of the one or more of the plurality of tethering cables to the anchoring element of the anchor block,
• fastening the second end of the one or more of the plurality of tethering cables to the anchoring element of the anchor block while held in position by the winch, and
• detaching the winch wire from the one or more of the plurality of tethering cables.
