SSEN Yell Substation: Peat Excavation and Carbon Risks for Shetland Wind Farms

SSEN is moving forward with a new substation in Yell to support the Energy Isles and Beaw Field wind farms. The project requires excavating over 2,000 cubic metres of peat, raising concerns about carbon loss and soil stability in a region known for peat slides. While official mapping classifies the site as high value carbon storage, contractors argue the land is already degraded. The plan involves reusing all excavated peat on site to maintain ecological stability and meet environmental guidelines.

The real story here is Statkraft asking to push Beaw Field back to 2031. SSEN is building the substation now, but if the generation side keeps slipping, we are just digging up peat for a stranded asset. What is the actual capacity this substation is rated for?

It is a classic mismatch between infrastructure timelines and project finance. The carbon accounting for the peat loss is likely being offset by the projected wind gains, but those gains are now pushed back a decade. The net carbon benefit of this specific dig just took a hit.

Interesting that the contractor is claiming the peat is degraded to downplay the ecological impact. National mapping says it is class one, but the guys on the ground say it is not. Usually, that gap is where the regulatory friction happens.

Exactly. If it is actually intact blanket bog, 2,000 cubic metres is a significant carbon release. Reusing it on site helps, but the disturbance itself often triggers oxidation.
