Client: Lunar Energy Limited


The EMECgrid-connected Fall of Warness tidal test site is located to the west of the island of Eday. The site covers an area of approximately 8km² and consists of 8 cabled test berths at depths ranging from 12 m to 50 m. The 11 kv subsea cables extend to the middle of the tidal stream from EMECs substation at Caldale in Eday which houses the main switchgear, backup generator and communications room.

Xodus (and the former AURORA Environmental Limited) has been providing support to the European Marine Energy centre (EMEC) since the early days of the planning stages of the facility. It has supported both EMEC during the development, consenting and early establishment of its tidal test facility, and to developers utilising the site to test their tidal energy technologies.

The scope of services provided is summarised below:

  • Site selection study for Highlands and Islands Enterprise (2001)
  • Co-author (with Aquatera) of EMEC device specific EIA guidance (2003)
  • Production of the environmental aspects of the integrated management system (legislation register & aspects identification) (2003 - 2005)
  • EIA and consent applications for the construction of the EMEC tidal test site, Fall of Warness (2005)
