Microgrid & Distributed Energy Equipment worked example

Controls Commissioning Load with connected commissioning load of 30 kW: a worked example in microgrid & distributed energy equipment

What does the result look like when connected commissioning load reaches 30 kW? The full calculation is worked below with real intermediate numbers. Use it when controls commissioning energy on a microgrid or distributed energy project needs a defensible number for the budget or quote.

The inputs for this scenario

  • Connected commissioning load: 30 kW (raised for this scenario; the documented default is 12)
  • Commissioning runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Controllers commissioned: 1,000 controllers (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where connected commissioning load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • A figure at this level is achievable when connected commissioning load is genuinely sustained, not just peaked for a shift. It assumes the connected load runs steadily for the full runtime; intermittent test loads, soft-start surges, or HVAC for the commissioning space are not captured and should be added separately.

Results at a glance

  • Controls commissioning energy used: 240 kWh (headline result)
  • Total controls commissioning energy cost: 28.8 $
  • Energy cost per controller: 0.03 $ / piece
  • Hourly controls commissioning energy cost: 3.6 $ / hr
