5-Year TCO Calculator — Right-Sized vs Oversized Irrigation Pump

Estimate the five-year total cost of ownership delta between a right-sized BBP pump and an oversized or off-BEP unit on the same duty. Default values are taken from the Cadeo Group study presented at the Hydraulic Institute Technical Meeting (October 2022) and the DOE EERE Pump Life Cycle Costs Guide.

Calculations assume CO₂ intensity of 0.4 kg per kWh (US grid average), no demand-charge effects, and constant tariff over the five-year horizon. Diesel pumps are assumed at 40% engine efficiency per the Cadeo study; electric pumps are assumed at the BBP factory pump-and-motor efficiency band. Send your actual duty curve, current pump efficiency reading, and utility tariff for a project-specific TCO model returned within five business days.
