The Bundesnetzagentur published on 3 December 2025 the results of the first biomass tender held under the rules of the biomass package, with a bid deadline of 1 October 2025. 807 bids for 940 MW were submitted against a volume of 813 MW, and the weighted average winning price was 18.11 ct/kWh. This is clearly more than in April 2025, when the average reached 16.53 ct/kWh.

| Item | Value |
|---|---|
| Tender volume | 813 MW |
| Bids submitted | 807 (940 MW) |

| of which new installations | 33 bids, 63 MW |
| of which existing installations | 659 bids, 752 MW |
| Winning price, minimum | 11.00 ct/kWh |
| Weighted average | 18.11 ct/kWh |
The tender was moderately oversubscribed: bids exceeded the volume by about 16%, much less than in April 2025, when submissions were almost three times the 187 MW volume. This time the volume was 813 MW. Earlier results are described in the article Germany: tender of 1 April 2025.
Geography of awards
By far the most awards went to Bavaria: 266 bids for 276 MW. Next came Lower Saxony (122 bids, 143 MW) and North Rhine-Westphalia (63 bids, 94 MW). This reflects the distribution of German agricultural biogas plants, concentrated in the south and north-west of the country.
Why the average price went up
The weighted average rose by about 1.6 ct/kWh relative to April 2025 (16.53 ct/kWh). With a smaller excess of bids over volume, price competition is weaker, so a higher average is not surprising. For comparison, the cap for existing installations is 19.83 ct/kWh, and for new ones 19.43 ct/kWh (a Bundesnetzagentur decision of 2024, maintained in 2025; see the article on the 2024 caps). The minimum winning price of 11.00 ct/kWh shows that some low-cost installations (e.g. with depreciated assets) could offer support well below the cap.
New installations still in the minority
There were 33 new installations for 63 MW, or about 8% of the capacity awarded. The remaining 752 MW went to existing biogas plants extending their operation. The total capacity of awards is, according to the Bundesnetzagentur, 815 MW, slightly more than the announced volume of 813 MW (the announcement does not explain this difference). Compared with April, when two bids for 0.3 MW received awards for new installations, this is a clear improvement, although still small. The new incentives for flexible capacity are described in the article Germany: Commission approves the biomass package.
At an exchange rate of approx. PLN 4.23 per euro (indicative, December 2025), 18.11 ct/kWh is approx. PLN 766/MWh.
