Netzanschlussablehnung und Betriebsuntersagung durch Zertifizierungsmangel

3 verified sources

Definition

Grid operators (TSOs/DSOs) retain authority to reject connection requests if certification is incomplete or falsified. VDE Renewables and accredited labs must validate grid conformity per BDEW MV guideline. Common rejection causes: (1) Incorrect unit certificate scope (e.g., inverter rated power mismatch), (2) Missing dynamic support tests (FGW TR4 simulation), (3) Firmware version mismatch between tested and installed inverter. Each rejection requires resubmission, recertification, and new grid compatibility test cycle—12–20 weeks. Operating ban risk if operator attempts to grid-feed without certification.

Key Findings

  • Financial Impact: €10,000–€50,000 per rejection in rework/recertification costs; 12–20 week delay × €25,000–€100,000/week lost revenue = €300,000–€2,000,000 aggregate impact
  • Frequency: ~5–8% rejection rate (Federal Grid Agency data); affects ~60–100 projects annually
  • Root Cause: Manual compliance documentation (no digital pre-check) + certification scope misalignment (manufacturer/installer/grid operator use different reference standards) + firmware versioning gaps post-certification
