Netzanbindungskosten-Überläufer bei Erneuerbaren Energien
Definition
Under § 8 EEG 2021, plant operators must cover all Netzanschlusskosten (grid connection costs). The 8-week grid compatibility test window (Netzverträglichkeitsprüfung) and multi-step certification (unit certificate + plant certificate per BDEW MV guideline and FGW TR3/TR4) create information asymmetry. Operators often underestimate civil works, transformer upgrades, and cable routing—discovering true costs only after KraftNAV application rejection or mid-construction changes. Grid operators have discretion to demand costly alternative access points; compensation is negotiated case-by-case.
Key Findings
- Financial Impact: €2,000–€8,000/MW in avoidable infrastructure costs; 40–80 hours of rework per project in grid access replan cycles
- Frequency: Monthly in German renewable energy projects; affects ~1,200+ new grid connection applications annually (BNA data)
- Root Cause: Fragmented approval process (Federal Grid Agency, Amprion, TransnetBW operate independently with non-standardized cost models). No early-stage cost transparency tool. Manual feasibility analysis = high error rates.
