Germany’s federal grid agency BnetzA has launched a 670MW third onshore wind tender this year with a price ceiling of €63 per megawatt hour ($73.50/MWh) of electricity produced.

The volume is lower than the usual 700MW, as the agency subtracted pilot wind installations built last year from the round.

Only wind projects with a permit under federal noise-emission rules are allowed to take part, a rule the Bundestag, Germany’s lower house of parliament, recently extended for another two years after exemptions from the regulation for community power projects last year distorted auction results.
