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.
