Our operations

Project development

The proposed Docking Shoal Offshore Wind Farm is located approximately 14 km (8.7 miles) from Wells-next-the-Sea on the North Norfolk coast and 19.5 km (12.1 miles) from Skegness on the Lincolnshire coast at its closest points.

The proposed site boundary was slightly modified from the original awarded site following the collection and evaluation of site data and detailed consultations with statutory consultees and stakeholders.

Grid connection

We undertook a feasibility study into possible grid connections for all three of our Round 2 wind farm developments (Lincs, Docking Shoal and Race Bank). In October 2005 we received and accepted grid connection offers for all three sites from National Grid at the existing Walpole substation.

Subject to consent, export cables from the wind farms will be buried within the seabed and then once onshore buried underground to Walpole. An extension to the existing National Grid owned substation at Walpole will be required to transform the power from the chosen export voltage to 400kV before being delivered into the national electricity network.

Environmental assessments

When assessing consent applications, Government ministers are required to consider the potential impacts of projects. To help this process we carried out an Environmental Impact Assessment (EIA) and submitted an Environmental Statement (ES) with our consent application in early December 2008.

The ES has been considered by key stakeholders and subjected to public scrutiny and comment. Comments received during the consultation period will be taken into account by the consenting authorities when they decide whether consent should be granted or refused.

Centrica held exhibitions to give members of the public the opportunity to see the Environmental Statement and to ask questions about the proposed project. The dates and venues were advertised and publicised through the local media in Lincolnshire and north Norfolk.

Supplementary Environmental Information (SEI)

Since submission of the ES for Docking Shoal, additional work has been voluntarily undertaken and the resulting information published in September 2009:

• Population Viability Analysis (PVA) of the north Norfolk Sandwich tern population

  In response to a request from stakeholders, Centrica has commissioned a population modelling study to investigate the potential effects of the proposed Docking Shoal Offshore Wind Farm on the Sandwich tern colonies at Scolt Head and Blakeney Point, part of the North Norfolk Coast Special Protection Area.

• Surveys of additional areas of the proposed export cable corridor including an impact assessment

  Following detailed engineering design work and discussions with stakeholders regarding the location of special features of interest, three additional areas have been surveyed to allow minor alterations to the original cable route. The report provides information on the bathymetry, seabed topography, sub-surface geology and biology of these areas, and a revised proposed cable route.

• Revised wireframe and photomontage images showing what the proposed wind farms would look like

  Centrica has prepared revised images based on new photographs incorporating the constructed Lynn and Inner Dowsing Offshore Wind Farms (now operational) and following the new guidelines for larger sized images. The new images present a clearer representation of how the wind farms may look when viewed from the selected viewpoints on the north Norfolk and Lincolnshire coastlines.

  The photomontages are available on CD by request at the details below, or alternatively are available to view in hard copy at the public viewing locations, also listed below. (Please note, due to the large file sizes and specific page sizing guidelines the photomontages were unable to be put on this website).

The supplementary information should be read in the context of the detailed information provided in the original Environmental Statement and the accompanying Non-Technical Summary.
