Lashy Sound Tidal Array
In December 2012, Scotrenewables Tidal Power Ltd. (SRTP, now Orbital Marine Power) was awarded an "Agreement for Lease" (AfL) from the Crown Estate for an area of seabed in Lashy Sound (also known as Eday Sound) for up to 30 MW of installed capacity. SRTP planned to develop and deploy a tidal array of up to 15 turbines installed over two phases: first up to 5 turbines (10 MW) would be commissioned between 2016 and 2019, and then 10 additional turbines (20 MW) would be commissioned in 2020.
The main components likely to be installed as part of the project include: fifteen 2 MW floating tidal turbines; mooring system including anchors, connection systems, cabling and mooring turrets; offshore electrical cabling infrastructure, including inter-array cabling and subsea export cable; cable landfall point and onshore grid connection to the substation building; and onshore substation building and associated infrastructure .
After the release of a scoping report in 2014, no further substantial information was released regarding progress in the development of this project.
