National Grid Gower coast cable burial: design and risk notes for engineers
National Grid submitted plans to Swansea Council to bury a section of overhead electricity line on the Gower peninsula, aiming to remove pylons from a protected coastal landscape. The project involves trenching and duct installation, with key challenges including working in sensitive coastal ground conditions and minimizing environmental impact. National Grid has experience in similar projects, such as the Grain to Tilbury cable tunnel under the Thames.
