Subsea cable plan for Scottish wind farm revealed

27 October 2008 – Plans to build a sub-sea interconnector cable to export electricity to the Scottish mainland from windfarms on Lewis have been lodged with the Scottish Government.

The cable would run from Gravir, South Lochs, down the hillside and under a salmon farm to reach out of the mouth of Loch Odhairn sea loch. The cable would be laid on the seabed across the Minch to Dundonnell at the head of Little Loch Broom. Cabling would then run to Beauly, near Inverness.

A separate upgrade of the Beauly to Falkirk grid is also being sought.

Scottish Hydro Electric Transmission, a subsidiary of Scottish and Southern Energy, has also submitted its plans to the Western Isles and Highland councils.

A separate planning application is expected for a transmission network on Lewis linking Gravir, Eishken, North Lochs and Arnish.

A converter station on the hill above Gravir would be the centralised collection point for the power before it is transmitted through a giant cable running beside houses under Loch Odhairn and across the Minch to Ullapool.

The multimillion-pound underwater link would export energy from the neighbouring Feiriosbhal windfarm and, potentially, from the awaited Eishken scheme.
