Plans to build an offshore wind farm near the island of Tiree off the west coast of Scotland have been ditched.
ScottishPower Renewables (SPR) said it would not go ahead with the Argyll Array following a number of technical and environmental studies.
The energy firm confirmed it has given up its lease for the project, which would have had a capacity of up to 1,800MW – enough to power a million homes. It has been working on the wind farm since 2009 but put the project into a 12-month freeze last year.
The decision to drop the development work was taken by SPR and the Crown Estate, which manages the seabed around the UK.
SPR said that while the site “may be viable to reconsider as offshore wind technology develops in the longer term”, that would not be for at least a decade.
The company said: “The main issues affecting the progression of the project are the ground conditions in the site, particularly the presence of hard rock, coupled with challenging wave conditions which could impact construction. Beyond this, there is a significant presence of basking sharks, which environmental groups continue to study to get a greater understanding of their movements in the area.”
SPR however said it remains committed to offshore wind projects in the UK, including its 389MW West of Duddon Sands wind farm which is currently being built in the Irish Sea with DONG Energy.
