Year of issue 2025
Date of issue 2025.08.14
The Bundesnetzagentur has today announced the successful bids in the auction that ended on 1 July 2025 for ground-mounted solar photovoltaic (PV) installations and solar installations on a construction that is neither a building nor a noise barrier ("first-segment solar installations").
"Competition is still keeping award prices well below the price ceiling,"
said Klaus Müller, President of the Bundesnetzagentur. "Award prices have been stable for more than a year now. Sustained competition also provides a reliable framework for bidders in the auction."
Auction again oversubscribed
The auction round that ended on 1 July 2025 was again oversubscribed. The auction was for a volume of 2,266 megawatts (MW). There were 313 bids with a total volume of 2,820 MW, of which 258 with a combined volume of 2,271 MW were successful. A total of 36 bids were excluded from the proceedings.
The prices of the successful bids in the pay-as-bid auction ranged from 4.00 cents per kilowatt hour (ct/kWh) to 6.26 ct/kWh. The average volume-weighted award price in this round was 4.84 ct/kWh, slightly above that of the previous round (4.66 ct/kWh).
The federal state with by far the most volume awarded was, as in previous rounds, Bavaria (689 MW, 106 winning bids), followed by Rhineland-Palatinate (251 MW, 23 winning bids) and Lower Saxony (250 MW, 18 winning bids).
