ROI Calculation Logic

Assuming an average 5% increase in annual power generation per wind turbine, annual electricity sales revenue could increase by ~$1M (AI est.). Furthermore, a 15% reduction in vortex generator manufacturing defect rates could yield ~$1M (AI est.) in annual manufacturing cost savings (e.g., 500 units/year production, ~$1.3K/unit defect cost (AI est.)). This totals an estimated ~$2M/year economic impact per facility.
