The Bundesnetzagentur, Germany’s energy regulator, announced on Tuesday the results of the auction for ground-mounted photovoltaic (PV) installations and solar installations on non-building, non-noise barrier structures, which concluded on December 1, 2025.
After two consecutive rounds that saw a decline in proposals, the latest auction has sparked renewed interest from the sector, with more than double the number of bids compared to the previous round. In total, 634 bids totaling 5,247 megawatts (MW) were submitted for an auctioned volume of 2,328 MW, reflecting significant oversubscription.
“The high level of participation demonstrates the attractiveness of the auction framework conditions,” said Klaus Müller, President of the Bundesnetzagentur.
Of the 634 bids received, 262 bids totaling 2,341 MW were ultimately awarded, while 61 bids were excluded from the process.
Winning bids under the pay-as-bid system ranged from 4.40 to 5.30 euro cents per kilowatt-hour (ct/kWh). The volume-weighted average price was 5.00 ct/kWh, a slight increase compared to the previous round, which stood at 4.84 ct/kWh.
By region, Bavaria again led the awarded volume, with 901 MW across 112 winning bids, followed by Saxony-Anhalt with 282 MW and 24 projects, and Brandenburg with 216 MW and 16 awarded bids.
The most successful bids were for projects located along highways and railways, with 125 awarded bids totaling 1,150 MW, highlighting the sector’s interest in leveraging existing infrastructure corridors for solar development.
The second-largest category by awarded volume was farmland or pastures in “disadvantaged” areas, with 88 bids totaling 874 MW. These are lands with low agricultural suitability, making them particularly suitable for PV installations without significant conflict with farming activities.
In third place were “special solar installations”, with 30 winning bids totaling 204 MW, representing about 9% of the awarded volume. These projects involve dual land use, combining electricity generation with other activities such as agriculture, in line with the development of agrivoltaic solutions.
