Microgrid & Distributed Energy Equipment worked example

Field Install Labor at 12% access, rigging, and commissioning allowance: a worked example in microgrid & distributed energy equipment

Push access, rigging, and commissioning allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when a microgrid or distributed energy field install changes unit count, crew rate, or allowance and you want to see the impact on hours.

The inputs for this scenario

  • Equipment units to install: 120 units (unchanged)
  • Install completion rate: 12 units / hr (unchanged)
  • Access, rigging, and commissioning allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base field install hours = equipment units to install รท install completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required field install hours, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base field install hours.
  • At this operating point the engine returns 12 % for access and commissioning allowance applied.
  • At this operating point the engine returns 12 pieces / min for install completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where access, rigging, and commissioning allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • It computes required field install hours by dividing the unit count by your install completion rate, then scaling up by an access, rigging, and commissioning allowance. 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

  • Required field install hours: 11.2 hr (headline result)
