Residents in the Kyle of Sutherland, a designated Highland beauty spot, are mounting opposition against proposals by German energy firm RWE to construct a substantial battery energy storage system (BESS) and an accompanying wind farm.
The planned development, sited within 400 metres of local homes, would feature 144 BESS units and 20 wind turbines, some reaching heights of up to 230 metres. This scale of development is notable as one of Scotland’s largest to integrate both a BESS compound and a wind farm.
The proposed BESS facility alone would occupy an area larger than two football pitches and is intended to store energy generated by the wind farm. Battery Energy Storage Systems are crucial for modern grids, storing surplus renewable energy during high production and releasing it during periods of low generation or high demand, thereby enhancing grid stability. RWE, a multinational energy company, is significantly invested in expanding renewable energy and storage technologies globally.
The Inveroykel project is slated for land managed by Forestry and Land Scotland, an executive agency of the Scottish Government. Campaigners, represented by No Ring of Steel Kyle of Sutherland (NORoS), have condemned the plans as “mass industrialisation by stealth” of a vital ecological area. They highlight the potential impact on the River Oykel and the wider Kyle of Sutherland, which is protected as a Special Area of Conservation (SAC) and Site of Special Scientific Interest (SSSI). This region is a known habitat for iconic wildlife, including ospreys, Atlantic salmon, and the critically endangered freshwater pearl mussel.
Tisi Dutton, a spokesperson for NORoS, stated: “The RWE plans would be devastating for the local community and are totally out of step for such a biodiverse, scenic and rural location.”
“This is mass industrialisation of our precious countryside and the Scottish Government is sitting by and simply letting it happen, without fully considering the devastating consequences.”
Local concerns also extend to the broader impact of renewable energy infrastructure across the region. The RWE proposal is one of 13 wind farm developments currently planned for the area, potentially leading to a total of up to 231 wind turbines encircling villages such as Culrain, Altass, and Rosehall.
These wider plans include proposals from EnergieKontor for “mega structures” of up to 250 metres in height, comparable to Edinburgh’s Arthur’s Seat. The combined generating capacity of these developments is suggested by campaigners to exceed that of the Sizewell B nuclear plant, which has a capacity of approximately 1,250 MW.

Campaigners also raise concerns about the clearing of over 200 acres of trees, including ancient woodland, a claim disputed by developers. They argue that the existing electricity grid infrastructure struggles to manage current energy output, citing UK constraint payments to operators, which reached approximately £1.9 billion in 2024/25. These payments are often made to conventional generators, such as gas plants, to increase output when renewable energy is curtailed due to network limitations.
In response, an RWE spokeswoman affirmed the company’s commitment to the project: “A comprehensive Environmental Impact Assessment has been carried out, examining potential effects on landscapes, wildlife and nearby communities.”
“This has directly shaped the project design, with mitigation measures embedded to avoid or minimise impacts wherever possible.”
