Regulatorische Übergangsverluste durch NEST-Implementierung (2025-2029)

2 verified sources

Definition

Bundesnetzagentur published NEST determinations Dec 2025 with major changes: (1) shift to WACC-based return on capital calculation, (2) annual vs. multi-year revenue cap adjustments for investment approval, (3) efficiency benchmarking for ~900 network operators. Each TSO must re-engineer billing systems, financial reporting templates, and regulatory submission processes. Estimated per-TSO implementation: 200-400 hours of specialist consulting + internal FTE time.

Key Findings

  • Financial Impact: Estimated: €2-5 million per large TSO for NEST transition (2025-2029); €500K-1.5M per mid-sized TSO. Industry-wide: €15-30 million (estimated for all German network operators)
  • Frequency: One-time transition costs (2025-2029); ongoing compliance cost increase post-2029 due to more frequent revenue cap resets (annual for new investments vs. prior multi-year cycles)
  • Root Cause: Regulatory volatility driven by CJEU independence ruling; Bundesnetzagentur forced to replace parliament-derived rules with administrative determinations, requiring full system redesign

Steigende Redispatch-Kosten durch Netzengpässe

Estimated: €50-150 million annually across German transmission network (typical range for large European TSOs; exact figure not disclosed in regulatory documents as of Dec 2025)

Dynamische Netzentgelte - Implementierungsunsicherheit (2029+)

Estimated: €5-15 million per large TSO for dynamic pricing IT infrastructure (once decision is finalized); 30-50% efficiency loss if implementation delayed vs. early movers

NIS2-Bußgelder und Betriebsunterbrechungen durch mangelnde Incident Response

LOGIC-estimated: €10,000–€50,000+ per incident (typical DACH regulatory penalties); Operational risk: Potential grid outages affecting 100,000+ households (revenue impact unquantified).

Manuelle Feasibility-Studien und hohe Bearbeitungskosten

Estimated €50-150K per feasibility study × ~6,000 non-approved annual requests = €300-900M annual waste; TSO administrative overhead estimated €100-250M/year; €15-40K per TSO employee per month in overtime during peak submission periods

Strafzahlungen für Nicht-Einhaltung der 24-Stunden-Lieferantenwechsel-Frist

Estimated €50,000–€200,000 annually per medium-sized supplier (based on typical penalty structures and volume of switches); 10–15 hours/month of manual verification labor

Regulatorische Mehrkosten durch fragmentierte Netzentgeltstruktur

Schätzung: 3–8% der jährlichen Netzentgelt-Verwaltungskosten (ca. €15–40 Mio. pro Großnetzbetreiber) durch regulatorischen Overhead und Rework.
