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 Randi Lucie Aliaga (rla@ens.dk) or Anders Møller Jørgensen (anmj@ens.dk) and include the following information:
- Applicant name (company name or name of the consortium)
- Applicant’s contact person, (name)
- Applicant’s contact person, (email)
- 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 for the new site. Reports, which are related to the environment and other reports, which do not require FTP server, will be posted on this page.
