Use this crop irrigation energy cost calculator to turn operational assumptions into a clear planning estimate. Enter the measurements from your project, field, or greenhouse, then review the main result alongside the supporting totals. The calculator keeps the formula visible so you can check units, compare scenarios, and understand exactly which assumptions drive the answer.
The estimate separates consumption-based charges from any fixed or demand charges entered.
Use actual motor input power and the applicable tariff; nameplate output power may understate electricity drawn.
An 18.5 kW pump running 10 hours for 120 days uses 22,200 kWh. At $0.14/kWh plus $350, estimated cost is $3,458.
The result changes directly with the quantities in the formula. Change one field at a time to see which operating assumption has the largest effect on cost.
Use the units printed beside each field. Convert measurements before entering them when a different unit is shown, because the built-in constants assume the displayed units.
Run separate scenarios for each period or operating condition, then add the applicable totals. A single blended input can hide important peaks and delays.
No. It includes only the losses, efficiency factors, or allowances shown in the input panel. Add separate allowances for conditions not represented.
Actual performance can differ because of measurement error, weather, equipment condition, work sequencing, material variability, and the quality of the assumptions entered.
