Submerged in about 40 meters (44 yards) of water off Scotland’s coast, a turbine has been spinning for more than six years…
The MeyGen tidal energy project off the coast of Scotland has four turbines producing 1.5 megawatts each, enough electricity collectively to power up to 7,000 homes annually.
For sure, but meygen is way too big for most fast moving tide races. And most places that are deep enough don’t have a fast enough current. The pentland firth is unusual in that it is both deep enough and has a current in the order of around 10 - 15 knots in places. It flows like a relatively fast moving river. It’s not a normal stretch of water.
