Client: Brims Tidal Array Ltd
In late 2008 the UK’s Crown Estate began a competitive leasing round for the development of 1,600MW of marine energy around Orkney and the Pentland Firth. Under this leasing round, Brims Tidal Array Ltd (BTAL), a joint venture between OpenHydro and SSE Renewables, was awarded an agreement for lease to support a 200 MW tidal array project off the south coast of the Orkney island of Hoy. The project will be built out in stages over three to four years, commencing once all necessary consents and grid infrastructure are in place.
Xodus was awarded specialist studies in fish ecology, commercial fisheries and underwater noise, in support of the EIA that was being undertaken / contributed to by a range of different specialists. As well as production of the ES chapters, Xodus also contributed to the Habitat Regulations Assessment (HRA) in the assessment of impacts on protected fish species.
The Marine Licence and Section 36 applications (which the ES supported) for the offshore elements of the project have been submitted to Marine Scotland in June 2016.Scope
