Wind power in Scotland Robin Rigg Wind Farm in the Solway Firth is Scotland's only commercial-scale, operational offshore wind farm, sited at Robin Rigg, a sandbank midway between the Galloway and Cumbrian coasts in the Solway Firth. It has 60 Vestas V90-3MW wind turbines with a total installed capacity of 180 MW. Scotland is also home to two offshore wind demonstration projects: The two turbine, 10 MW Beatrice Demonstrator Project located in the Moray Firth, and the single turbine, 7 MW Fife Energy Park Offshore Demonstration Wind Turbine in the Firth of Forth. There are also several other commercial-scale and demonstration projects in the
Firth "firth" (e.g. the Minch and Loch Torridon); instead, these are often called sea lochs. Before about 1850, the spelling "Frith" was more common.
