Located on a natural plateau at an average of 700m above sea level, Dunmaglass is SSE’s highest wind farm to be constructed.

Stronelairg onshore wind farm

SSE acquired the project from RES in May 2013 and initial enabling works began in the summer of 2013. This included the upgrade of 11km of tracks and the construction of two timber deck bridges.

Highland contractor RJ McLeod was awarded the £16m main civil works contract in summer 2014. These works included the construction of the 33 turbine bases and crane hardstandings and associated cabling and drainage works.

The height of Dunmaglass wind farm presented its challenges during construction and the winter months brought high winds and plenty of snow. The site was fully completed and handed to the operations team in 2017.

In February 2019, SSE signed agreements for the sale of 49.9% of Dunmaglass wind farm to Greencoat UK Wind Plc (“UKW”). This sale was part of a £635m deal in which Greencoat acquired a 49.9% stake in both Stronelairg and Dunmaglass wind farms. The stakes equate to 160.6MW (megawatts) of capacity, with an average valuation for the two wind farms of around £4m per MW.  This valuation demonstrates SSE’s ability develop quality, low carbon assets and infrastructure vital to the GB energy market.
