A planning application made to The Highland Council for the 5 turbine redesigned Cairnmore Hill Wind Farm proposal, was refused by the Council in January 2025 under delegated powers. 

The proposal is sited in an area identified by The Highland Council as having ‘potential for wind farm development’ and outwith any nature conservation, landscape or cultural designations. It would have been capable of generating clean, low cost renewable electricity for around 28,000¹ homes and offsetting approximately 23,736 tonnes of carbon emissions compared to the use of fossil fuels. The proposal also included measures to enrich key habitats across the site and achieve a 16% biodiversity net gain. In addition, it was predicted to deliver around £2.1 million of inward investment to the local area and £8.75 million in business rates to the Council  - in addition to a tailored community benefit package for the local area. 

In May 2025, a Statement of Appeal was submitted to the Scottish Government’s Directorate for Planning and Environmental Appeals (DPEA) against The Highland Council’s decision to refuse the Cairnmore Hill Wind Farm application.

Cairnmore Hill Wind Farm was acquired by TagEnergy in November 2025 as part of their first UK investment in wind farms. RES will support TagEnergy in the delivery of Cairnmore Hill Wind Farm through the provision of development services.

^{1The 28,000 homes equivalent figure has been calculated by taking the predicted annual electricity generation of the site together with RES’ predicted capacity factor of 49.66% and dividing this by the annual average electricity figures from DESNZ showing that the annual GB average domestic household consumption is 3,239 kWh (January 2024). Final wind farm capacity will vary depending on the outcome of planning permission and the turbine type selected.}
