ROI Calculation Logic

Assuming a 5% average improvement in power conversion efficiency for a distributed generation system. For an annual power consumption of 3 million kWh at a unit cost of $0.13/kWh (AI est.), the annual cost reduction is 3 million kWh × $0.13/kWh × 0.05 = $19.5K (AI est.). Applying this to 10 standard factory sites yields $195K (AI est.) annually. Considering extended device lifespan and reduced maintenance, the total annual cost reduction could reach $1.0M (AI est.).
