AUC vs. DUC
In 2024, the terminal AUC was -11.8% (or -19.24 €2017) lower than the planned DUC. This results from the combination of significantly lower than planned terminal costs in real terms (-6.4%, or -1.9 M€2017) and significantly higher than planned TNSUs (+6.1%). It should be noted that the actual inflation index in 2024 was +10.4 p.p. higher than planned.
Terminal service units
The difference between actual and planned TNSUs (+6.1%) falls outside the ±2% dead-band, but does not exceed the ±10% threshold foreseen in the traffic risk sharing mechanism. The resulting gain of additional terminal revenues is therefore shared between the ANSP and the airspace users (see the main ANSP gain in Box 11).
Terminal costs by entity
Actual real terminal costs are -6.4% (-1.9 M€2017) lower than planned. This is the result of lower costs for the main ANSP, AirNav Ireland (-8.6%, or -2.3 M€2017) and higher costs for the MET service provider (+15.2%, or +0.2 M€2017) and the NSA (+12.2%, or +0.2 M€2017).
Terminal costs for the main ANSP at charging zone level
Significantly lower than planned terminal costs in real terms for AirNav Ireland in 2024 (-8.6%, or -2.3 M€2017) result from:
- Slightly higher staff costs than planned (+0.8% or +10.4% in nominal terms) explained by “higher general wage increases than forecast in the contex of high inflation during RP3. In addition, there were higher costs of overtime partially offset by lower headcount than planned”,
- Slightly lower other operating costs (-0.7% or +8.8% in nominal terms),
- Significantly lower depreciation (-29.9%), due to delays in project completion caused by resource shortages in engineering and operations, leading to prioritisation of ongoing operations over investments. Project delivery was also hindered by regulatory changes (Commission Implementing Regulation (EU) 2019/317),
- Significantly lower cost of capital (-17.2%), due to a lower actual asset based than planned.
RP3 summary
When considering the whole of RP3 (2020-2024) for Ireland terminal charging zone, actual TNSUs are +5.6% higher than planned, while actual costs in real terms are -2.7% lower than the determined costs (some -3.5 M€2017). As a result, the weighted average actual unit cost over RP3 (175.29 €2017) is -7.9% lower than planned in the PP (190.32 €2017).
