Final Run Test Load with test stand connected load of 30 kW: a worked example

Push test stand connected load up to 30 kW and the picture changes. This example computes every intermediate figure at that operating point. a test or operations team needs the energy cost of end-of-line run testing to budget it or fold it into a quote

The inputs for this scenario

  • Test stand connected load: 30 kW (raised for this scenario; the documented default is 12)
  • Run test hours: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Units run-tested: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total run test energy cost = test stand connected load × run test hours × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for run test energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total run test energy cost.
  • At this operating point the engine returns 0.03 $ / piece for run test energy cost per unit.
  • At this operating point the engine returns 3.6 $ / hr for hourly run test energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where test stand connected load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • It computes total run-test energy in kWh, the energy cost of the test, the cost allocated per unit, and the hourly energy cost of the test stand. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Run test energy used: 240 kWh (headline result)
  • Total run test energy cost: 28.8 $
  • Run test energy cost per unit: 0.03 $ / piece
  • Hourly run test energy cost: 3.6 $ / hr
