Wind Repowering in Lower Saxony

With over 13 GW of installed onshore capacity, Lower Saxony is the German state with the largest wind fleet. Around 1,800 turbines reach the end of their EEG funding period between 2025 and 2030 — a huge repowering market with strong competition for sites, turbines and engineering consultancies.

Market Data

Turbine fleet	approx. 6,300 turbines
Installed capacity	13.0 GW
Share of German fleet	21%
Repowering candidates 2026–2030	approx. 1,800
Top regions	East Frisia (Ostfriesland), Lüneburg Heath (Lüneburger Heide), Wendland, Cuxhaven

Permitting & Law

Minimum setback: no blanket state rule — TA Lärm (technical noise guidance) + LAI shadow-flicker guidance decide, typically 600–1,000 m
Authority: Landkreis (district authority, the permitting body), Staatliches Gewerbeaufsichtsamt (state trade supervision office) for noise + emissions
WaLG target (Wind-an-Land-Gesetz, Wind-on-Land Act): 2.2% by 2032 (interim target 2027: 1.4%); current status: approx. 1.3% designated
Regional planning: 4 regional associations, a very pronounced tradition of priority areas (Vorranggebiete)
Species-protection focus: red kite (Rotmilan) inland, white-tailed eagle (Seeadler) near the coast, black stork (Schwarzstorch) in the heath

Permitting Practice

Lower Saxony has a well-established turbine permitting practice. Processing times average 6–10 months in the simplified procedure (§ 19) and 12–20 months in the formal procedure (§ 10). Litigation level: moderate — BUND/NABU regularly file suits where protected areas are nearby.

Specific Points for Lower Saxony

High wind acceptance in the wind-tradition regions (East Frisia, Wendland)
Strong cooperative scene: many community wind projects, especially citizen-energy transition
Top coastal sites: 3,500+ full-load hours, market-value risk from wind cannibalisation
WaLG status critical: if the 1.4% target is not met by 2027, the exclusionary effect of concentration zones lapses
