When wind turbines reach the end of their standard 20-to-30-year operational design life, project operators generally evaluate options between repowering, major component refurbishment, or complete decommissioning. Repowering involves replacing aging internal machinery, generators, and blades with modern, high-efficiency technology while utilizing existing foundation towers and grid connections. If the entire site is decommissioned, towers are dismantled, concrete bases are buried, and recyclable steel and metallic components are salvaged, though composite fiberglass blades require specialized processing.
