AUC vs. DUC
The AUC for the combined year 2020-2021 is lower than the planned DUC (by -3.1%, or -12.44 €2017). This is due to the combination of lower than planned TNSUs (-0.5%) and lower than planned terminal costs in real terms (by -3.6%, or -2.4 M€2017).
Terminal service units
The difference between actual and planned TNSUs (-0.5%) falls within the ±2% dead band. Hence the resulting loss is borne by the ANSP.
Terminal costs by entity
Actual real terminal costs for 2020-2021 are -3.6% (-2.4 M€2017) lower than planned. This result is driven by the main ANSP, Skeyes (-3.7%, or -2.4 M€2017), while the NSA costs are -0.5% lower than planned.
Terminal costs for the main ANSP at charging zone level
Overall, the terminal costs in real terms for Skeyes in 2020-2021 were lower than the determined costs from the performance plan (by -3.7%, or -2.4 M€2017 lower). This results from:
- lower staff costs (-2.4%),
- lower other operating costs (-9.4%),
- lower depreciation (-0.9%); and
- lower cost of capital (-5.5%).
The additional information to the reporting tables provides no qualitative information explaining the reasons underlying the differences between the determined and actual costs.
