Microgrid & Distributed Energy Equipment worked example

Field Install Labor at 7.2% access, rigging, and commissioning allowance: a worked example in microgrid & distributed energy equipment

Suppose access, rigging, and commissioning allowance falls to 7.2%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the field labor hours to install microgrid and distributed energy equipment on site, including access and commissioning allowance, so teams can plan crews, schedule the install, or check whether it fits the outage or shift window.

The inputs for this scenario

  • Equipment units to install: 120 units (held at the documented default)
  • Install completion rate: 12 units / hr (held at the documented default)
  • Access, rigging, and commissioning allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base field install hours = equipment units to install รท install completion rate.
  • Required field install hours works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base field install hours works out to 10 hr at these inputs.
  • Access and commissioning allowance applied works out to 7.2 % at these inputs.
  • Install completion rate works out to 12 pieces / min at these inputs.

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 2.55% below the baseline at 10.72 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. 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

  • Required field install hours: 10.72 hr (headline result)
  • Base field install hours: 10 hr
  • Access and commissioning allowance applied: 7.2 %
  • Install completion rate: 12 pieces / min

Run it with your numbers

  • To rerun this with your own numbers, open the live Field Install Labor calculator, set access, rigging, and commissioning allowance to your actual value, and adjust the remaining inputs to match your operation.
