Pump costs: energy economics of electric pumps?

As pump power increases, pump costs per kWh decrease. The most significant reduction is in pump maintenance costs, while the total cost of electricity remains constant.

Total pump costs can be ballparked at $600/kW/year of power, of which 70% is electricity, 20% operations and maintenance, 10% capex/capital costs. But the numbers vary. Hence this data-file breaks…
