We drove past a massive wind farm construction on Mainland Shetland. It is the Viking Wind Farm. You can see the crane lifting parts up on the right hand mast. At the moment it sounds as though it will be 103 turbines with a nameplate output of 443MW. This is much higher than the diesel power station in Lerwick but is much more variable and will depend heavily on the capacity factor. However, it is clearly more than the islands need in terms of electricity. For that reason, a cable is being connected to the north coast of Scotland.
