Data Hub Preliminary Investigation of Sites

Pursuant to Sec. 16 of the Offshore Wind Energy Act (WindSeeG), the Federal Network Agency (BNetzA) will determine the addressee and the amount of support under the Renewable Energy Sources Act (EEG) by means of a call for tenders since 2021 onwards for wind turbines at sea that are commissioned from January 1, 2026 onwards. The location, timing and sequence of the areas to be tendered are determined in each case by the Site Development Plan (FEP).

The sites defined in the FEP are examined by the Federal Maritime and Hydrographic Agency (BSH) in accordance with Sec. 9 et seqq. WindSeeG. The preliminary site investigation comprises studies on the marine environment (Sec. 10 para. 1 no. 1 WindSeeG), the preliminary investigation of the subsoil (Sec. 10 para. 1 no. 2 WindSeeG) as well as the investigation of the wind and oceanographic conditions on the area to be tendered (Sec. 10 para. 1 no. 3 WindSeeG). In addition, the BSH may specify further subjects of investigation, in particular on the basis of the results of the hearing (Sec. 12 para. 3 sentence 2 WindSeeG).

The results of the investigations and related documents are made available via the data hub. The provision serves the fulfillment of the legal obligation from Sec. 19 sentence 2 no. 7 WindSeeG.

Further information on the subject of preliminary site investigations can be found on the BSH homepage.
