AUC vs. DUC
In the combined year 2020-2021, the terminal AUC was +1.7% (or +10.9€2017) higher than the planned DUC. This results from the combination of higher than planned TNSUs (+0.4%) and higher than planned terminal costs in real terms (+2.1%, or +7.8 M€2017).
Terminal service units
The difference between actual and planned TNSUs (+0.4%) falls within the ±2% dead band. Hence the resulting additional terminal revenue is kept by the ANSPs.
Terminal costs by entity
Actual real terminal costs are +2.1% (+7.8 M€2017) higher than planned. This is driven by the main ANSP, DSNA (+2.4%, or +7.9 M€2017), and NSA costs (+32.6% or +0.8 M€2017), whereas costs for the MET service provider are -3.0% (or -0.9 M€2017) lower than planned.
Terminal costs for the main ANSP at charging zone level
The higher than planned terminal costs in real terms for DSNA (+2.4%, or +7.9 M€2017) result from:
- slightly lower staff costs (-0.1%);
- higher other operating costs (+11.5%);
- lower depreciation (-2.7%), mainly in relation with the postponement of some commissioning from 2021 to 2022 and the transfer of investment costs to project related OPEX costs;
- higher cost of capital (+6.7%), due to increase in both asset base (+2.3%) and WACC (+0.1 p.p.);
- higher deduction for VFR exempted flights (+1.4%).
