Electric GSE Charger Compatibility Cost at 98% fleet coverage included in scope: a worked example

Push fleet coverage included in scope up to 98% and the picture changes. This example computes every intermediate figure at that operating point. an airport equipment planner needs to estimate the cost to make electric GSE units compatible with station chargers

The inputs for this scenario

  • Electric GSE units needing charger work: 42 units (unchanged)
  • Charger compatibility cost per GSE unit: 1,850 $ / unit (unchanged)
  • Fleet coverage included in scope: 98 % (raised for this scenario; the documented default is 85)
  • Fixed charger integration cost: 28,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Covered fleet compatibility cost = GSE units needing charger work × compatibility cost per unit × fleet coverage included) to the inputs above produces each figure below.
  • At this operating point the engine returns 104,146 $ compatibility cost for total charger compatibility cost, the number this scenario is built around.
  • At this operating point the engine returns 2,480 $ / piece for compatibility cost per gse unit.
  • At this operating point the engine returns 76,146 $ for covered fleet compatibility cost.
  • At this operating point the engine returns 28,000 $ for fixed charger integration cost.

How this compares with the baseline

  • Against the tool's baseline example, where fleet coverage included in scope sits at 85% and the headline result is 94,045 $ compatibility cost, this scenario comes in 10.74% above the baseline at 104,146 $ compatibility cost.
  • It calculates total charger compatibility cost as covered per-unit work plus a one-time fixed integration cost, and back-solves the effective cost per unit. 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

  • Total charger compatibility cost: 104,146 $ compatibility cost (headline result)
  • Compatibility cost per GSE unit: 2,480 $ / piece
  • Covered fleet compatibility cost: 76,146 $
  • Fixed charger integration cost: 28,000 $
