The Offshore Wind Energy Act (WindSeeG) entered into force on 1 January 2017 as part of the 2017 Renewable Energy Sources Act. The Act stipulates that the level of funding for offshore wind-power installations is also to be determined by means of competitive auctions. It additionally ensures dovetailing between site planning, regional planning, approval of installations, funding under the Renewable Energy Sources Act, and grid connection. This will improve the system and render it more cost-effective. The aim is to boost the installed capacity of offshore wind energy installations to a total of 15 gigawatts between 2021 and 2030, following a set plan and in a cost-efficient manner.
