AUC vs. DUC
In 2024, the terminal AUC was +5.3% (or +11.76 €2017) higher than the planned DUC. This results from the combination of significantly lower than planned TNSUs (-7.6%) and lower than planned terminal costs in real terms (-2.7%, or -0.9 M€2017).
Terminal service units
The difference between actual and planned TNSUs (-7.6%) falls outside the ±2% dead-band, but does not exceed the ±10% threshold foreseen in the traffic risk sharing mechanism. The resulting loss of terminal revenues is therefore shared between the ANSP and the airspace users (see the main ANSP loss in Box 11).
Terminal costs by entity
Actual real terminal costs are -2.7% (-0.9 M€2017) lower than planned. This is the result of lower costs for the main ANSP, skeyes (-2.7%, or -1.0 M€2017) and higher costs for the NSA (+1.5%, or +0.01 M€2017).
Terminal costs for the main ANSP at charging zone level
Lower than planned terminal costs in real terms for skeyes in 2024 (-2.7%, or -1.0 M€2017) result from:
- Significantly lower staff costs (-7.2%), mainly due to “lower number of FTE, which is a direct result of ongoing recruitment challenges in an increasingly tight labour market”,
- Higher other operating costs (+4.5%), mainly driven by a provision for major building maintenance following the decision to renovate an existing facility instead of rebuilding it,
- Significantly lower depreciation (-14.0%), mainly due to delays in commissioning radio sites and IT-related projects, including the VCS Main System and the SAT for WAN, caused by supplier issues and difficulties obtaining permits,
- Significantly lower cost of capital (-38.3%), “mainly due to a lower fixed asset base”,
- Exceptional costs which reflect a reporting of negative amount (-2.0 M€ in nominal terms) in 2024 determined costs for skeyes to correct for the difference between planned and actual costs in 2021-22 resulting from resubmission of the RP3 PP.
RP3 summary
When considering the whole of RP3 (2020-2024) for Belgium terminal charging zone, actual TNSUs are -2.9% lower than planned, while actual costs in real terms are -3.8% lower than the determined costs (some -6.4 M€2017). As a result, the weighted average actual unit cost over RP3 (278.83 €2017) is -0.9% lower than planned in the PP (281.22 €2017).
