The Federal Network Agency has announced the results of the auction that closed on December 1, 2025, for ground-mounted solar projects and solar projects on structures that are neither buildings nor noise barriers. The auction was oversubscribed, with 634 bids submitted for a total capacity of 5,247 MW against a tendered volume of 2,328 MW. Out of these, 262 bids amounting to 2,341 MW were awarded, while 61 bids were excluded from the process.
The awarded tariffs in the pay-as-bid auction ranged between €0.044 per kWh and €0.053 per kWh. The volume-weighted average tariff stood at €0.05 per kWh, slightly higher than the previous round’s €0.0484 per kWh. Bavaria secured the largest share of awarded capacity, securing 901 MW capacity from 112 bids. Additionally, Saxony-Anhalt received 282 MW from 24 bids, followed by Brandenburg with 216 MW from 16 bids.
Most successful bids were for projects planned alongside motorways and railway corridors, accounting for 125 bids with a combined capacity of 1,150 MW. Furthermore, farmland and grassland in disadvantaged regions formed the second-largest category with 88 bids totalling a capacity of 874 MW. Special solar installations, which combine electricity generation with secondary land use such as agriculture, accounted for 30 bids totalling 204 MW, reportedly representing nearly 9 per cent of the awarded volume.
REGlobal’s Views: Germany has conducted a host of auctions over the past few months across solar power, wind power as well as biomass to accelerate deployment of clean power capacity. Solar installations have been on the rise in Germany, enabled by supportive policies as well as such auction mechanisms. Solar power is comparatively easier to install than other sources especially on farmlands, rooftops and balconies. In fact, the country witnessed a higher capacity addition in rooftop solar when compared to ground-mounted in early 2025.
