The Pentland Road wind farm being built near Stornoway had just received a ship delivery of huge turbines to be built on Lewis.
Another consignment for the six turbine Pentland Road wind farm is due from Germany.
Developer Peter Crone was deeply dismayed at the announcement of the subsea cable.
Though much of his scheme will feed into the local grid it needs the subsea cable to export a surplus 4.2MW output.
Mr Crone said it would mean a loss of £30,000 a year to crofters and community interests because their turbines would not be able to generate their maximum output.
He said: “This has a knock-
Scott Maciver of Maciver Consultancy Services which is supervising the building of the Pentland Road wind farm said the delay will have an negative impact on all island wind projects.
He highlights it would restrict the Pentland Road development’s generating output.
He added: “The bigger wind farm are completely reliant upon the subsea connector so, without it, these will not be able to go ahead.”
Mr Maciver reckons the big developers with planning permission are now be reconsidering their options as “they will be working to timescales for construction and with the delay they will have to review their programmes.”
He stressed wind farm construction would provide a huge number of construction jobs with maximum local labour hired.
