Commissioning Load with connected electrical load during commissioning of 6 kW: a worked example

Suppose connected electrical load during commissioning 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 commissioning load for mining vehicle and underground equipment using production-ready inputs so teams can budget energy cost, compare equipment settings, or include electricity in the quote.

The inputs for this scenario

  • Connected electrical load during commissioning: 6 kW (the input this scenario stresses; the baseline uses 12)
  • Commissioning run time: 8 hr (held at the documented default)
  • Blended electricity rate: 0.12 $ / kWh (held at the documented default)
  • Machines commissioned during the run: 1,000 units (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where connected electrical load during commissioning sits at 12 kW and the headline result is 96 kWh, this scenario comes in 50% below the baseline at 48 kWh.
  • It computes commissioning energy in kWh, the total energy cost, the energy cost per machine, and the hourly cost from connected load, run time, rate, and units. 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.
