At Golticlay Wind Farm, being delivered by Farrans for RWE, one of the most significant challenges facing the project team has been the management and restoration of peat across the site.
Peatland habitats play a vital role in carbon storage and biodiversity, making their protection a key consideration throughout the development and construction of renewable energy infrastructure.
Recognising the environmental sensitivity of the site, Farrans worked closely with our client and the wind farm owner RWE, during the early stages of the project and throughout the PCSA phase to develop a comprehensive Peat Management Plan (PMP).
The PMP detailed how peat would be excavated, handled, stored and reinstated across the site, ensuring compliance with environmental requirements and best practice guidance. Given the importance of the peatland habitat, the PMP and wider strategy underwent consultation and review with key stakeholders (including NatureScot and Peatland Action) before being approved. All excavated peat has been retained on site.
The management of excavated peat on the Golticlay site involved the implementation of an innovative technique aimed at integrating the excavated peat within the peatland habitat restoration operations, as a new, sustainable ways to valorise the peat resource on wind farm sites.
The ultimate goal of this technique is to achieve the restoration of degraded peatland habitats in areas immediately adjacent to the wind farm infrastructure on previously forested sites. This involved integrating excavated peat within the traditional ground smoothing operations to raise the local water table and establish hydrological conditions which favour the revegetation of peat-forming species and re-functionalisation of the excavated peat. The technique also minimises peat handling and storage time and thus reduces the environmental impacts of excess peat handling and the drying of peat stored for long periods of time.
