It’s around 15 miles west-northwest of the town of Wick next to the A9 main road on the way to Thurso. The wind farm is situated on Dale Moss, a large area of peatland commanding views across the wilderness of the Flow Country to Morven, the highest point in Caithness. The land below the turbines is also used for grazing cattle.

The site was originally developed by nPower in 2003 before being transferred to Beaufort, then Infinis and now Ventient Energy. Its 21 turbines are rated at 2.3MW and the site has an installed capacity of 48.3MW, generating enough energy to power 29,259 homes*.

Benefiting local communities

The nearest community to Causeymire is at Spittal just to the north of the wind farm site while the the village of Halkirk (with an estimated population of c.970) is around 5 miles further north. The nearest town is Thurso (pop. 7600) which is close to the decommissioned Dounreay nuclear plant. The local, highly skilled work force is increasingly involved in the growing renewable energy and grid infrastructure sectors, unlocking the potential for wind, wave and tidal power developments in the area.

The Halkirk community has established The Halkirk District Benefit Fund to administer income from Causeymire Wind Farm and awards grant funding to local causes. Recent beneficiaries of the fund have included Caithness Indoor Riding School, Halkirk Community Sports Foundation and Halkirk Heritage and Vintage Motor Society.
