Environmental statement

Surveying at Hornsea Project One‚Äč

An Environmental Statement (ES) is a document reporting the assessment of the environmental effects of the project development and is produced in accordance with the EIA Directive as transposed into UK law by the EIA Regulations. It includes:


  • A description of the development comprising information on the site, design and size of the development;
  • A description of the measures envisaged in order to avoid, reduce and, if possible, remedy significant adverse effects;
  • The data required to identify and assess the main effects which the development is likely to have on the environment;
  • An outline of the main alternatives studies by the applicant and an indication of the main reasons for the applicant's choice, taking into account the environmental effects;
  • A Non-Technical Summary of the information provided.


A full environmental impact assessment (EIA) was undertaken for Hornsea Project One informed by a number of project specific data collection surveys and studies to characterise the site. These surveys included offshore surveys within the export cable corridor and array area to gather data on seabed conditions and sediments, oceanographic surveys and ecological surveys.  Onshore surveys were also undertaken and  included ecological surveys (bird, bat and reptile), archaeological surveys and visual assessments.


The Non-Technical Summary is available on our downloads page  Non- Technical Summary.


The full Environmental Statement is available on the Planning Inspectorate website Full Environmental Statement.
