German solar developers seek €70/MWh auction ceiling for 2027

· Energy · Germany

Fifteen German solar developers are calling for the auction ceiling for ground-mounted solar to be raised from €59 ($65.91) per MWh to at least €70 per MWh for 2027. They warn that planned changes to Germany's renewable energy law, grid connection rules and network charges could raise ground-mounted solar costs by up to 30%. The group argues the higher ceiling is needed to keep projects viable under the new cost structure, putting them at odds with the current auction design as Germany revises its renewables framework.

Why it matters：Germany's auction ceiling and grid-charge rules will determine whether ground-mounted solar buildout stays economically viable in Europe's largest market.

  • Developers want the ceiling raised from €59 to at least €70 per MWh for 2027
