Sefferweich wind farm is a wind farm in Germany with a capacity of 20 MW, commissioned in 2001. It is operating and is owned by Energie-Windpark Islek GmbH & Co.KG.
In 2024 it settled 21.0 GWh of electricity, a load factor of 12.0%. Part of that volume was sold outside EEG support, so it is partly merchant. This figure is apportioned across units of the same site that share a registry entry.
Its EEG support ran to the end of 2023.
This asset produced at 12.0% of nameplate in 2024 — the 20th percentile of German wind commissioned pre-2010 (182 assets with metered output). Its volume is apportioned across phases sharing one registry entry, so treat the figure as an estimate for this unit and exact for the site.
