In 2024, we have progressed on this action by ordering more than 300 refurbished yaw brake calipers on our East and West Coast hubs in the UK. Calipers are used to hold the nacelle in place when the brakes are applied and are a part of the hydraulic system. For each caliper we reuse, we also lower the cost of our wind farm maintenance. In addition, we have set up refurbishment loops for several other minor components with a long leadtime to reduce the risk of lost production.

The technical materials for constructing new assets are tracked to provide a detailed understanding of material usage and composition for offshore and onshore renewable energy projects (offshore wind, onshore wind, solar PV, and battery storage assets (BESS) above 100 MW). Material inflows reflect assets currently under construction within the reporting year. Our in-house LCA analysis forms the foundation of the methodology, with the highest maturity for offshore assets. External verified studies supplement the project-specific data for battery energy storage systems (BESS), solar PV, and onshore wind. Material usage is accounted for when main components are recognised as installed. This process involves detailed mapping of materials associated with each main component to ensure accurate tracking and reporting.
