Germany is reaffirming its commitment to onshore wind expansion by maintaining the full volume of its upcoming tender, totalling 3,443,164 kilowatts (3.44 GW). The Federal Network Agency (Bundesnetzagentur) announced that it will not apply the adjustment clause under Section 28(6) of the Renewable Energy Act (EEG), which permits a volume reduction when a low number of bids is anticipated.
“The Federal Network Agency will not reduce the tender volume for the bid submission deadline of 1 May 2025,” the official statement reads. Since 1 May is a public holiday in Germany, the deadline has been postponed to the next business day, Friday, 2 May 2025, in accordance with Sections 188 and 193 of the German Civil Code (BGB).
“The deadline for this event is Friday, 2 May 2025,” the Agency specifies. Bids must be physically received at the Bonn headquarters (Tulpenfeld 4, 53113 Bonn) no later than midnight on that date.
Technical and administrative requirements
Only projects that have been authorised under the Federal Immission Control Act (BImSchG) and registered by 3 April 2025 will be eligible to participate.
All submissions must strictly comply with the digital formatting requirements set by the Agency. Forms are to be downloaded from the official website and completed using a PDF reader such as Adobe Acrobat Reader.
“Handwritten forms do not meet the formatting requirements,” the Agency stresses. Any deviation from the specified format will automatically disqualify the offer.
The mandatory documents include the tender form, financial guarantee, turbine extension details (if applicable), and proxy authorisations. “A separate guarantee must be submitted for each bid,” the notice emphasises.
The maximum allowable bid value has been set at 7.35 euro cents per kilowatt hour. “If the bid exceeds the maximum value, the offer will be excluded from the award procedure,” the Agency states clearly.
This ceiling ensures competitive pressure among participants while preserving the financial stability of the support scheme.
One-quarter of 2025’s 10-GW target
This tender covers one-quarter of Germany’s 10,000-MW onshore wind target for 2025, as laid out in Section 28(2) of the EEG. The annual volume is equally distributed across four bidding rounds. Adjustments may also be made in accordance with subsections 3 and 5 of the same provision.
Despite having the legal capacity to reduce the volume in the face of expected under-subscription, the Federal Network Agency has chosen to maintain its full capacity offering.
“The tender volume refers to the sum of installed capacity for which financial support is awarded in a tendering round,” the Agency highlights.
Regulatory clarity and procedural simplification
The Agency confirmed that no additional regulations under Section 85(2) EEG have been issued for this specific procedure. Unused cash guarantees, overpaid fees, and other financial surpluses will be refunded after the publication of the tender results, although it may take up to six weeks due to internal and external audit procedures.
To streamline processing, participants are discouraged from submitting unnecessary documentation, such as cadastral extracts, former project IDs, or declarations of land ownership.
“Refraining from sending unnecessary documents represents a considerable relief,” the Agency notes, highlighting efforts to simplify procedures for applicants.
Market outlook
According to the Agency’s data, authorisations for new onshore wind projects surged in the first quarter of 2025, suggesting that more eligible developers will be positioned to submit compliant bids in the upcoming round.
According to the Onshore Wind Energy Agency (Fachagentur Windenergie an Land), more than 4 GW of wind capacity was approved in the first quarter of the year, a record for the country.
Permitting for onshore wind projects had already seen a surge last year, with more than 14 GW authorized by 2024, anticipating a faster pace of onshore expansion within Europe’s largest wind market.
Germany’s decision to preserve the full 3.4-GW tender volume sends a strong message of regulatory consistency and commitment to the country’s energy transition objectives. For investors and developers alike, this transparency and firmness provide a predictable environment for long-term planning.
