Abstract
Orsted Hornsea Project Three (UK) Ltd., on behalf of Orsted Power (UK) Ltd., is promoting the development of the Hornsea Project Three Offshore Wind Farm (hereafter referred to as Hornsea Three). Hornsea Three is a proposed offshore wind farm located in the southern North Sea.
The Hornsea Three array area (i.e. the area in which the turbines are located) is approximately 696 km2, and is located approximately 121 km northeast off the Norfolk coast and 160 km east of the Yorkshire coast (Figure 1.1). The Hornsea Three array area lies to the east of Hornsea Project One and Hornsea Project Two offshore wind farms, and is located within the former Hornsea Zone (as shown on Figure 1.1). Hornsea Three is a project that will consist of an offshore generating station(s) with a capacity of greater than 100 MW and therefore is a Nationally Significant Infrastructure Project (NSIP), as defined by Section 15(3) of the Planning Act 2008. As such, there is a requirement to submit an application for Development Consent to the Planning Inspectorate (PINS) to be decided by the Secretary of State for Business, Energy and Industrial Strategy.
The Hornsea Three application for Development Consent has been submitted to PINS with the prescribed forms and documents as required by the Infrastructure Planning (Applications: Prescribed Forms and Procedure) Regulations 2009.
The purpose of the Environmental Statement is to provide the environmental information which has been gathered in order to carry out an assessment of the likely significant environmental effects of Hornsea Three. The Environmental Statement specifically:
- Provides statutory and non-statutory consultees with technical information to enable an understanding of Hornsea Three;
- Presents the existing environmental baseline information, established from desktop studies, offshore and onshore surveys and consultation;
- Describes the methodology used within the Environmental Impact Assessment (EIA) process;
- Presents the potential environmental impacts arising from Hornsea Three, based upon the baseline information and data gathered, and the analysis and impact assessments completed;
- Indicates any limitations encountered during the compilation of the environmental information, including the acknowledgement of any data gaps or deficiencies and confidence in the information gathered;
- Puts forward potential mitigation measures that could prevent, minimise, reduce or offset potential adverse environmental impacts identified during the EIA process. Where additional mitigation measures have been identified, the residual significance of effect has also been identified; and
- Provides an outline of the main project alternatives
