Microgrid Capacity Gap at 99% asset availability: a worked example

This scenario runs the microgrid capacity gap calculation on the strong side: 99% asset availability, with every other input held at its documented default. Use it when a microgrid is asked to carry more critical load and you need to know whether deliverable capacity covers peak demand.

The inputs for this scenario

  • Usable energy delivered per dispatch interval: 4 kWh / interval (unchanged)
  • Number of available dispatch intervals: 480 intervals (unchanged)
  • Asset availability: 99 % (raised for this scenario; the documented default is 90)
  • Battery round-trip efficiency: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross microgrid capacity = usable energy per dispatch interval × available dispatch intervals) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 kWh for deliverable microgrid capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 kWh for gross microgrid capacity.
  • At this operating point the engine returns 19.2 kWh for availability loss.
  • At this operating point the engine returns 57.02 kWh for round-trip efficiency loss.

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 10% above the baseline at 1,844 kWh.
  • Use it when sizing storage or validating a dispatch or demand-response commitment against realistic, derated energy rather than nameplate. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Deliverable microgrid capacity: 1,844 kWh (headline result)
