ROI Calculation Logic

If this technology is implemented, a 100MW wind farm (assuming 10 turbines) could see its annual power generation increase by 15% from approximately 350 million kWh, resulting in an additional 52.5 million kWh annually. At a wholesale electricity price of $0.067/kWh (AI est.), this translates to an annual revenue increase of ~$3.5M (AI est.). Furthermore, improved aerodynamic performance could reduce maintenance frequency and extend component lifespan (estimated at a 10% reduction in annual operating costs). Combined, the total economic impact is estimated at ~$3.5M per year (AI est.). Calculation: (350 million kWh annual generation × 0.15 × $0.067/kWh) + (annual operating cost reduction)

~$3.5M annually.
