Germany’s Onshore Wind Build Surged in 2025 With a Wider Regional Divide

Record approvals in 2025 point to faster build‑out despite stark disparities between leaders and laggards.

Overview

  • Germany commissioned 958 onshore turbines adding 5,232 MW in 2025, lifting gross additions by 58% year over year.
  • Permits reached an all‑time high with 3,310 turbines authorized totaling 20,765 MW, signaling a robust near‑term pipeline.
  • Schleswig‑Holstein added 143 turbines (789.9 MW) to rank third by new capacity, with repowering accounting for 24.4% and the state leading installation density at 609 kW per km².
  • Turnover in Schleswig‑Holstein included the retirement of 78 older units (about 122 MW), resulting in a net gain of 65 turbines and 668.2 MW.
  • Thuringia contributed just 13 turbines (71.6 MW), obtained approvals for 475 MW, retired 20 older units, and passed a law allowing the state forestry authority to develop wind projects in forests.
