ROI Calculation Logic

For a medium-scale hydropower plant, assuming 2 manual debris removal operators at ~$67K/person/year (AI est.) and 2 planned outages per year causing ~$33K/outage (AI est.) in opportunity loss. This technology could reduce manual work by 70% and eliminate 1 planned outage. This translates to (~$67K * 2 * 0.7) + (~$33K * 1) = ~$94K + ~$33K = ~$127K in direct savings (AI est.). Additionally, increased operating rate could generate ~$73K/year (AI est.) in additional power, totaling ~$200K/year in economic benefits.

Speed to Market
