Germany’s Federal Maritime and Hydrographic Agency, the Federal Maritime and Hydrographic Agency (BSH), has launched amendment procedures for the country’s Site Development Plan (Flächenentwicklungsplan, FEP), introducing changes aimed at improving the energy yield and economic viability of future offshore wind projects.
The proposed revisions include lower installed capacity densities and optimised site layouts designed to reduce wake effects between turbines and increase electricity generation. The changes also affect offshore wind areas that failed to attract bids in Germany’s 2025 auction round.
For the sites N-10.1 and N-10.2, which received no bids in 2025, BSH has outlined three alternative boundary configurations. The aim is to reduce capacity density and improve project economics ahead of a planned reauction in 2027.
Under the amendment proposal, four offshore wind sites with a combined capacity of 4 GW are scheduled for auction in 2027. These include N-10.1 and N-10.2 with a combined capacity of 2.5 GW, N-13.1 with 0.5 GW and N-13.2 with 1 GW.
For sites N-12.4 and N-12.5, whose auction was suspended in 2026, BSH has not proposed a new auction date for 2027. The agency said the timing of a future tender will be determined at a later stage.
The proposed changes form part of efforts to align offshore wind site planning more closely with actual electricity production and support Germany’s target of reaching 70 GW of offshore wind capacity by 2045.
