4. Key Market Opportunity
A major opportunity in the Composite Repair Market is the expansion of wind blade leading edge erosion repair programme demand as the global onshore and offshore wind fleet ages beyond 10 years of operation and leading edge erosion affects. A significant proportion of global onshore wind blades installed before 2015 have reached the 10-year service age at which leading edge erosion becomes visible and performance-impacting requiring repair or protective coating application at above-baseline blade O&M expenditure. Wind blade leading edge erosion repair programme using polymer paste and composite repair kit restoring blade aerodynamic profile recovers annual energy production lost from blade roughness induced by erosion at operating wind site AEP improvement. Repair material producers that develop wind blade leading edge repair systems validated for AEP recovery, build wind turbine O&M service contractor distribution, and scale material supply for growing global blade fleet repair programme demand are positioned to capture growing.
