Wind Turbine Repowering in Germany

Repowering means replacing older wind turbines with modern, higher-capacity units at the same or nearby site. The German market is the largest in Europe — driven by ~6,500 turbines reaching end-of-EEG-funding between 2025–2027.

Typical Configuration

Parameter	Old (pre-2010)	New (2026)
Turbine count	8 × 1.5 MW	3 × 6.0 MW
Hub height	67 m	165 m
Rotor diameter	66 m	162 m
Total capacity	12.0 MW	18.0 MW
Full load hours	~1,900 h/yr	~3,000 h/yr
Annual yield	~22.8 GWh	~54.0 GWh
Yield multiplier	1.0×	2.4×

The Repowering Process — 7 Phases, 24–36 Months

Site assessment (1–3 months): wind data, regulatory framework, environmental factors
Turbine selection & lease negotiation (3–6 months)
Permit planning (6–12 months): all mandatory expert reports — bird survey is the critical path (one full season minimum)
BImSchG permit application (4–18 months): simplified procedure 4–8 months, formal procedure with EIA 18+ months
EEG auction (parallel): after permit, participation in Bundesnetzagentur quarterly auctions
Dismantling & construction (8–14 months)
Commissioning & market entry (2–4 months)

Regulatory Framework

BImSchG — Federal Immission Control Act, primary permit framework
EEG 2024 — 20-year market premium, current ceiling 7.35 ct/kWh, auction-based
WaLG (2022) — federal states must designate 2.2% of land area for wind by 2032; non-compliance suspends concentration zone effects
§ 35 BauGB — privileged status in outdoor areas since 1996
§ 44 + § 45b BNatSchG — species protection with standardized taboo radii for 15 collision-prone bird species

Economic Indicators (2026)

CAPEX: 1,200–1,700 EUR/kW (repowering 5–10% lower than greenfield)
OPEX: 20–30 EUR/MWh (typical full-service maintenance contract)
LCOE: 40–95 EUR/MWh depending on site quality
IRR: 7–10% typical for repowering projects
WACC: 4–5% (senior debt 70–80%, equity 20–30%)

Cost Comparison: Repowering vs. Continued Operation

Example for an 8 × 1.5 MW park, EEG ending 2022:

	5y continued operation	Repowering 3 × 6 MW
Investment	EUR 0.5 M (BNK retrofit)	EUR 25 M
Annual yield	22 GWh/yr	54 GWh/yr
Price per MWh	50 EUR (PPA)	72 EUR (EEG)
Annual revenue	EUR 1.1 M	EUR 3.9 M
Cash flow	EUR 0.3 M/yr × 5y	EUR 3.0 M/yr × 20y

Key insight: Repowering becomes economically dominant where site quality supports it. Site wind speed ≥ 6.5 m/s at 150 m hub height is the threshold for clearly profitable repowering (versus continued operation).

Critical Bottlenecks in 2026

Turbine delivery: 12–18 months lead time from major manufacturers (Vestas, Enercon, Nordex, Siemens Gamesa)
Expert offices: accredited acoustic and species-protection consultants are 8–14 months backlogged
Approval authorities: in Brandenburg, Schleswig-Holstein, Lower Saxony — heavily loaded

Common Questions

Can I get EEG remuneration for a repowering project?

Yes — repowering projects compete in the BNetzA auctions like new builds. No separate "repowering bonus" exists since 2017.

What about south Germany?

Bavaria's 10H rule (10× total height as minimum distance) restricts repowering, but the WaLG could suspend it if the state misses its 2027 land-area target. Watch the regulatory development closely.

What financing structures are typical?

Project finance with 70–80% senior debt from specialized German energy banks (NORD/LB, KfW IPEX, Bayern LB), 20–30% equity from sponsors, mandatory citizen participation in MV, BB, NRW.
