German wind developer Wpd has filed a complaint to Germany’s constitutional court against the Wind Energy at Sea Act (WindSeeG) after its far-offshore project Kaikas in the North Sea was excluded from future offshore wind tenders without compensation to the developer.

Wpd in 2013 had won a license to build 80 turbines at Kaikas.

But the Federal Maritime and Hydrographic Agency BSH in 2015 halted licensing procedures in the cluster more than 100km from the shore containing the project, which made it unlikely it would secure a grid access guarantee.
