Lewis Wind Power - Subsea Cable Route Study
ETA were selected by Lewis Wind Power (LWP) to identify potential grid connection points and subsea cable routes to link the proposed Isle of Lewis windfarm to the UK mainland. The potential capacity of the sub-sea cable was required to be in the range of 600-1200MW, with multiple cable configurations to be considered. Key to ETA's selection was the depth of knowledge demonstrated during the tender process, technical approach, and the ability to provide outputs in formats compatible with the client's GIS software.
The project
required investigation of six mainland grid connection points, the routing
of subsea and land cables, and identification of potential sites for converter
stations. Options for short length AC crossings and longer HVDC interconnectors
were presented. The route study took account of all factors relevant to the
construction and operation of the cables, including existing infrastructure,
land ownership, consents, oceanography and coastal processes, geology, fisheries,
and environmental factors. Preliminary consultation with stakeholders was
undertaken to identify relevant issues. Outputs to the client were provided
in hard copy and electronic formats, including design reports and cartography
of the final routes.
