Electric vs Diesel Running-Cost Calculator

Enter hours, load, power and fuel prices to compare an electric unit (DM / DMT / LGDY) with a diesel unit (CM / LGCY) of the same output

① Inputs

Electric model

Hours per yearAverage load (%)Share of loaded running, typically 50–80%Electricity price（USD / kWh）Diesel price（USD / L）Motor efficiency (%)Engine fuel use (L / kWh)Diesel engine power (kW)Filled from the matching diesel model — editableYears

② Estimate

Electric — power per year

Diesel — fuel per year

Electric

Diesel

Estimates for reference only — ask a KayDrill engineer for a site-specific figure. Maintenance differences beyond energy (engine oil, fuel filters, engine overhauls) are not included, so the real gap is usually larger.

③ Method

· Electric cost = motor kW × load ÷ motor efficiency × hours × electricity price
· Diesel cost = engine kW × load × fuel use (L/kWh) × hours × diesel price
· Annual saving = diesel cost − electric cost
