ROI Calculation Logic

For a medium-scale gas turbine power plant (50MW output), if this technology improves thermal efficiency by 5% compared to conventional methods, assuming 7,000 annual operating hours and a fuel cost of $0.07/kWh (AI est.), the annual fuel cost reduction is estimated at 50,000kW × 7,000h × $0.07/kWh (AI est.) × 5% = ~$1.2M (AI est.). Further maintenance cost reductions are also anticipated.
