North West Lewis

Lewis Wave Power plans to develop a wave energy array, using Aquamarine’s Oyster wave energy converter (WEC) technology, off Staca Mhic Cubhaig, approximately 2km north of Siadar, Lewis, Scotland. The array will have a generation installed capacity of up to 40MW and connect to the national grid. The array will consist of between 40 and 50 Oyster devices; depending on the design and therefore final power rating of the devices used. These devices will be positioned according to the best understanding of available wave resource, water depth, and seabed gradient and seabed protrusions. The wave array will be configured in a linear formation running roughly parallel to the coast and will run a distance of up to 3.2km from end to end.
