Plant Pump Energy Cost with pump motor load of 55 kW: a worked example

This scenario runs the plant pump energy cost calculation on the strong side: pump motor load of 55 kW, with every other input held at its documented default. estimating the electricity cost of pumping industrial fluids through a process step

The inputs for this scenario

  • Pump motor load: 55 kW (raised for this scenario; the documented default is 22)
  • Pump runtime: 6 hr (unchanged)
  • Blended electricity rate: 0.11 $ / kWh (unchanged)
  • Volume transferred: 18,000 gal (unchanged)

Working through the calculation

  • Applying the documented formula (Pump energy cost = motor load × runtime × electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 36.3 $ for pump energy cost, the number this scenario is built around.
  • At this operating point the engine returns 330 kWh for pump energy used.
  • At this operating point the engine returns 0 $ / gal for pump energy cost per gallon.
  • At this operating point the engine returns 6.05 $ / hr for pump hourly energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where pump motor load sits at 22 kW and the headline result is 14.52 $, this scenario comes in 150% above the baseline at 36.3 $.
  • Use it to cost a specific transfer, compare pumps or operating strategies, or build the energy component of a batch cost model. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
