Repowering Funding Under the EEG 2024
Under the EEG 2024 (Erneuerbare-Energien-Gesetz, Renewable Energy Sources Act), repowering turbines are treated identically to new-build turbines — they must successfully participate in a Bundesnetzagentur (BNetzA) auction to receive the 20-year market premium. A previously discussed repowering bonus no longer exists (abolished in 2017).
How Does the Funding Work?
- BImSchG permit (Federal Immission Control Act) required for the new turbines
- Participation in a BNetzA auction (4 dates per year)
- Successful bid below the ceiling price (2026: 7.35 ct/kWh)
- Award = "anzulegender Wert" (reference value) guaranteed for 20 years from commissioning
- Commissioning within 30 months of the award (penalty for delay)
- Marketing via direct marketer + market premium from the transmission system operator (TSO)
The "Anzulegender Wert" (Reference Value)
The "anzulegender Wert" is the bidder-specific remuneration rate guaranteed for the next 20 years. Current awards in 2026 frequently settle near the ceiling price of 7.35 ct/kWh (indicating high competition).
The market premium equals the difference to the monthly market value:
Market premium = reference value − monthly market value for wind
Bonus System
| Bonus | Value | When applicable |
|---|---|---|
| South bonus (Sudbonus) | +0.30 ct/kWh | Turbines in BW, BY, HE, RP, SL |
| Low-wind correction | variable | Site quality factor < 70% of reference site |
| Community wind participation | not in EEG | State laws in MV, BB, NRW (from 2025) |
| Repowering bonus | no longer exists | Abolished in 2017 |
Low-Wind Correction
Turbines at low-wind sites receive a correction factor that increases the remuneration compared to the northern German standard. This makes southern sites with lower wind resources economically viable:
| Site quality factor | Correction factor |
|---|---|
| ≥ 100% (reference site) | 1.00 (standard) |
| 90% | 1.11 |
| 80% | 1.29 |
| 70% | 1.49 |
| 60% | 1.77 |
| 50% | 2.07 (floor) |
The site quality factor is reassessed after 5, 10, and 15 years — the actual yield achieved is compared with the reference site, and the remuneration rate is adjusted retrospectively.
The 30-Month Deadline After Award
- Maximum 30 months from award to commissioning
- Delay penalty: 10 EUR/kW
- Non-commissioning: forfeiture of the award + additional penalty
- 6-month extension possible for documented supply chain delays (frequent in 2024–2026 due to manufacturer bottlenecks)

Repowering Without EEG (PPA / Self-Supply)
Alternatives to EEG funding:
- PPA with industrial off-taker: 10–15 year fixed price, typically 50–65 EUR/MWh — viable at prime wind sites
- Self-supply: direct power supply contract with nearby industrial consumer
- Spot market direct marketing: variable, current average 40–80 EUR/MWh — higher risk
Advantage: no auction bureaucracy, free commissioning timeline, longer contract periods possible. Disadvantage: no fixed-price security, harder to obtain bank financing.

Get in touchFrequently Asked Questions
What happens if the bid exceeds the ceiling price?
The bid is invalid — excluded from that auction round. Participation in the next round is possible. Since 2023, award values have been very close to the ceiling, indicating high competitive intensity.
Can we submit multiple bids per turbine?
Yes — each turbine site can be bid separately. For wind farm configurations, the entire project is usually submitted as one bid, though sometimes bids are staggered per individual turbine.
When does the 20-year funding period begin?
At commissioning (first power feed-in). For repowering projects, this is typically 2–3 years after the BImSchG application.
What happens after 20 years?
EEG funding ends — electricity is then marketed at spot market prices or via a new PPA. For a turbine repowered today, this means around 2046 — market conditions at that point remain open.
