Final Run Test Load with test stand connected load of 6 kW: a worked example

Suppose test stand connected load falls to 6 kW. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the electricity cost of end-of-line run testing for engines and equipment from test cell load, run hours, and your blended electricity rate.

The inputs for this scenario

  • Test stand connected load: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Run test hours: 8 hr (held at the documented default)
  • Blended electricity rate: 0.12 $ / kWh (held at the documented default)
  • Units run-tested: 1,000 units (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total run test energy cost = test stand connected load × run test hours × blended electricity rate.
  • Run test energy used works out to 48 kWh at these inputs, and this is the headline figure for the scenario.
  • Total run test energy cost works out to 5.76 $ at these inputs.
  • Run test energy cost per unit works out to 0.01 $ / piece at these inputs.
  • Hourly run test energy cost works out to 0.72 $ / hr at these inputs.

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 50% below the baseline at 48 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. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Run test energy used: 48 kWh (headline result)
  • Total run test energy cost: 5.76 $
  • Run test energy cost per unit: 0.01 $ / piece
  • Hourly run test energy cost: 0.72 $ / hr
