Questione giuridica chiave
Whether the synthetic valuation of pre-1999 network assets may be reduced by 20.5% in addition to the 20% rule-based deduction.
Decisione estratta
The additional 20.5% reduction was excessive; only the 20% deduction under Art. 13 Abs. 4 StromVV may be applied, not cumulatively on top of the corrective reduction.
Motivazione estratta
The synthetic method is an exception to estimate historical acquisition costs. The ElCom's comparative adjustment already corrects overvaluation; a further identical reduction would lower values below true acquisition costs and conflict with Art. 15 Abs. 1 and 3 StromVG.
