Triton Knoll Offshore Wind Farm Limited have been awarded EU TEN-E funding to support the development of the Triton Knoll Offshore Wind Farm Electrical System located in both UK Territorial waters and the UK’s Exclusive Economic Zone. The funding which is to be matched will support a number of surveys, engineering reports, and environmental impact assessment studies for the Triton Knoll Electrical System. The studies will form part of the formal documentation that will accompany the Development Consent Order which will be submitted to the Planning Inspectorate. The sum of €1,159,559 has been granted and the process to reclaim this funding is ongoing.

This study area covers the road network local to the proposed development as well as the key routes which connect the general area to the wider highway network. A small number of abnormal loads will be required during the construction programme. These loads will comprise the transformers and reactors at the Substation and reactors at the Intermediate Electrical Compound. The routes to be used by abnormal loads have been considered by Collett Transport and comprise the road network between potential incoming port locations and the Substation / Intermediate Electrical Compound. The movement of abnormal loads will be insignificant in number and will be escorted and managed on the road network. On the above basis, the study area comprises the A and B roads expected to be used to access the Temporary Construction Compounds (TCC’s) from the wider highway network, commencing with the principal roads of the A16, A17 and A52. Interconnecting A and B roads form the remainder of the study area with Marsh Lane through Orby, Sea Road at Anderby and Roman Bank at Anderby Creek as known minor roads that will serve the TCC’s. The TCC’s will also be served by a number of other minor roads, however these are not considered to be sensitive to the impacts of construction traffic due to the low number of properties being served, lack of pedestrian activity and low traffic volumes. The study area is illustrated in Figure 1-1 and is described in greater detail later in this report. 1.3 Character of the Existing Environment The existing environment has been characterised based on a number of sources, including: • Traffic count data from the Department for Transport; • Traffic count data from Lincolnshire County Council; • Personal Injury Collision Data from the Department for Transport; and • Traffic surveys commissioned by RWE. 1.3.1 Wider Highway Network Boston and Skegness are located within the County of Lincolnshire, on the eastern coast of the UK. Access to the wider strategic highway network is predominantly via Triton Knoll Offshore Wind Farm Ltd 1 Triton Knoll Electrical System, Triton Knoll Electrical System 80427 510000 520000 530000 540000 550000 560000 West Lindsey District A52 Legend: Proposed Development Boundary 380000 A1111 Administrative Boundary (District / Borough) Principal Road included in Study Area A16 !
