Seagen Anglesey Skerries
Site selection, feasibility assessments and environmental studies began in 2006 and a newly created development company, SeaGeneration (Wales) Ltd, was set up in 2008 as a joint venture between Marine Current Turbines (MCT) and RWE npower renewables to develop the project. No devices were ever deployed. The project was suspended and cancelled in 2014. MCT was subsequently bought over by tidal industry leader Atlantis Resources Ltd in 2015.
The location for the proposed array was a 0.56 km2 site between the group of rocks and islands known as the Skerries and Carmel Head. The site is less than 1km from the Anglesey coast and is characterised by water depths of around 20 to 40 m. Its close proximity to Holyhead made the site suitable due to access to good port facilities, the national grid and transport connections. The proposed array was planned to consist of up to 9 SeaGen devices and have a total installed capacity of up to 10 MW. The array was planned to operate for up to 25 years and serve as a test case for the development of the technology in multi device arrays.

Site Characteristics
Geographic characterization for the project location:
- Open Ocean: Main body of ocean, not enclosed or partially enclosed by land
- Coastal: Open water near the coast, spanning between land and shelf boundary
- Enclosed Bay: water that is partially surrounded by land, with a mouth open to larger water
