Preliminary investigations

In relation to the tendering of Hesselø Offshore Wind Farm, a range of preliminary investigations and environmental assessments are being carried out.

Results in the form of reports and data from the completed investigations can be accessed directly here at this site (reports) and through access to a FTP site (data), which is maintained by Energinet. All results from the preliminary investigations etc. are targeted potential bidders for Hesselø OWF.

Access to Energinet's FTP site

Access to Energinet’s FTP site is obtained in the following way:

Step 1: Interested bidders can request access to the data by notifying the Danish Energy Agency. Send the request to Therese Kofoed Jensen, email tkj@ens.dk, and include the following information:

  1. Applicant name (company name or name of the consortium)
  2. Applicant’s contact person, (name)
  3. Applicant’s contact person, (email)
  4. Applicant’s contact person, (telephone number)

Step 2: Energinet will thus send instructions to the applicant on access to the FTP server with username and password.

The FTP website will be updated in accordance with the plan mentioned in the table below. Reports, which are related to the environment and other reports, which do not require FTP server, will be posted on this page. A smaller part of the MetOcean data (report #102 and #103) will only be available in the beginning of 2021, and will exclusively be available for prequalified bidders, who has signed an NDA.

The preliminary investigations as well as the compilation of the complete environmental report (SEA) including the summarising statement and hearing will be completed by 1 April 2021 at the latest, in order for bidders to be able to familiarise themselves with these prior to the deadline for submitting final bids.
