Microgrid Capacity Gap at 65% asset availability: a worked example

Suppose asset availability falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate the usable energy a microgrid can deliver across dispatch intervals, after availability and round-trip efficiency, so resilience planners can compare it against peak load and see the capacity gap.

The inputs for this scenario

  • Usable energy delivered per dispatch interval: 4 kWh / interval (held at the documented default)
  • Number of available dispatch intervals: 480 intervals (held at the documented default)
  • Asset availability: 65 % (the input this scenario stresses; the baseline uses 90)
  • Battery round-trip efficiency: 97 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross microgrid capacity = usable energy per dispatch interval × available dispatch intervals.
  • Deliverable microgrid capacity works out to 1,211 kWh at these inputs, and this is the headline figure for the scenario.
  • Gross microgrid capacity works out to 1,920 kWh at these inputs.
  • Availability loss works out to 672 kWh at these inputs.
  • Round-trip efficiency loss works out to 37.44 kWh at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where asset availability sits at 90% and the headline result is 1,676 kWh, this scenario comes in 27.78% below the baseline at 1,211 kWh.
  • It computes gross dispatchable energy, then derates it by asset availability and round-trip efficiency to return deliverable capacity in kWh and the losses that create the gap. 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.
