The 653MW Markbygden Ett wind farm – a sub-project of Europe’s largest wind complex Markbygden – has filed for restructuring proceedings with the Umeå district court in northern Sweden after getting into financial difficulties, apparently due to an unprofitable power purchase agreement (PPA) with Norwegian aluminium giant Hydro.

The wind farm operator closed a corporate PPA with Hydro in 2017, which then was claimed to be the world’s largest green power offtake agreement.
