Repowering Market 2026
Germany is facing the largest repowering wave of the Energiewende (energy transition): many turbines built between 1996 and 2005 are reaching the end of their EEG funding period. At the same time, the federal government is pushing via the WaLG (Wind Energy Area Requirements Act) and EEG 2024 toward 115 GW of onshore wind capacity by 2030. The market is active, tight, and predictable.
Stock and Repowering Potential
| Metric | Value (as of 2026) |
|---|---|
| Onshore wind turbine stock in Germany | approx. 28,500 turbines |
| Installed onshore capacity | approx. 62 GW |
| Pre-2005 turbines in operation (repowering candidates) | approx. 9,000 |
| Reaching EEG end 2025–2027 | approx. 6,500 |
| Theoretical repowering potential (capacity addition) | 20–35 GW |
| BWE forecast repowering 2026–2030 | 5–7 GW per year |

Two Key Market Bottlenecks in 2026
- Turbine delivery times: manufacturer lead times currently 12–18 months from order. Very tight on the supply side — even major OEMs (Vestas, Enercon, Nordex) are fully booked.
- Expert availability: accredited acoustic, species-protection, and landscape-planning consultancies are at capacity. Booking the full expert report package currently requires 8–14 months lead time.
Repowering market 2026 — stock, regional distribution, and forecast
Market Participants
- Large operators: RWE, EnBW, Vattenfall, Iberdrola, ENERCON (own parks) — systematically repowering their 2002-era fleets
- Mid-size developers: ABO Wind, Energiekontor, juwi, BayWa r.e., NaturEnergie — often acting as service providers for site owners
- Community wind cooperatives: increasingly important, as many pioneer parks were community projects
- Institutional investors: growing institutional capital (wind as an asset class)
- Landowner alliances: farmers joining forces to repower under their own management
Repowering Strategies
- 1:1 swap: same number of turbines, new type — simplest procedure, WaLG (Wind Energy Area Requirements Act) streamlining benefits
- Consolidation: e.g. 8 turbines reduced to 3, higher capacity per unit, land freed up
- Expansion: developing additional sites in the vicinity (often constrained by community acceptance)
- Hybrid: adding solar PV on the same site — emerging pattern
Forecast 2026–2030
Expected trajectory according to BWE / WindGuard:
- 2026: approx. 1,500 MW repowering commissioned
- 2027: approx. 2,500 MW
- 2028–2030: 5,000–7,000 MW per year
- Cumulative by 2030: approx. 20–25 GW repowering additions (on top of new-build)

Get in touchFrequently Asked Questions
Why are so many turbines reaching EEG end simultaneously?
EEG funding started for many pioneer turbines in 2000–2005 with the first EEG legislation. 20 years later, the funding period expires in 2020–2025. This creates the historic repowering wave.
Are there regional bottlenecks?
Yes — permitting authorities in Brandenburg, Schleswig-Holstein, and Lower Saxony are particularly overloaded. Processing times often exceed 18 months. In Bavaria, the 10H distance rule significantly delays the maturation of the repowering market.
How do electricity prices affect the repowering rate?
Significantly — when electricity prices are high, continued operation of old turbines remains profitable longer, delaying repowering. When prices are low, repowering becomes the only economically viable option — triggering a repowering construction wave.
What does this mean for turbine delivery times?
Delivery times have increased considerably — current wait times for Vestas, Enercon, and Nordex are 12–18 months from order. Early reservation is worthwhile; some projects order turbines before receiving BImSchG approval (option contracts).
