1 INTRODUCTION

Overview

1.1 Triton Knoll Offshore Wind Farm Limited (TKOWFL) is submitting an application to the Planning Inspectorate (PINS), on behalf of the Secretary of State for Energy and Climate Change, for a Development Consent Order (DCO) for the Triton Knoll Electrical System (the proposed development) under the Planning Act 2008. The Triton Knoll Electrical System (TKES) would connect the consented Triton Knoll Offshore Wind Farm (TKOWF) offshore array to the existing National Grid substation at Bicker Fen, Boston. 1.2 The TKOWF is located approximately 33km (20.5 miles) east of the Lincolnshire coast. The Secretary of State granted a DCO for the TKOWF offshore array on 12th July 2013. 1.3 All terms, acronyms and abbreviations used within this outline plan are explained on first use, and / or set out in full within the Glossary appearing in the Environmental Statement - document reference 6.2.1.

The Applicant

1.4 TKOWFL is a joint venture between two leading international energy companies; RWE Innogy and Statkraft. RWE Innogy UK Ltd is the UK subsidiary of the German renewable energy company RWE Innogy (part of RWE AG), a company with a strong and diversified position in renewable energy development. Statkraft is Europe’s largest generator of renewable energy and is the leading power company in Norway.

Project Overview

1.5 The components of the TKES, which are needed to connect TKOWF to the National Grid, comprise:  Up to six offshore export cable circuits – to transmit the high voltage alternating current (HVAC) electricity from the offshore substations to the transition joint bays at the landfall;  Landfall infrastructure just north of Anderby Creek, Lincolnshire – including transition joint bays which house the connection between the offshore cables and the onshore cables;

Triton Knoll Offshore Wind Farm Ltd Triton Knoll Electrical System

 Up to six onshore export cable circuits (up to 220 kV) – to transmit the HVAC electricity from the transition joint bays at the landfall to the Substation via the Intermediate Electrical Compound;  An Intermediate Electrical Compound near to Orby Marsh – to provide compensation for reactive power to allow more efficient transmission to minimise losses;  A substation near the existing Bicker Fen National Grid Substation – to step-up the voltage to the voltage used by the National Grid and provide additional compensation for reactive power built up over the export transmission;  Up to four onshore export cable circuits (400 kV) – to transmit the electricity from the proposed Triton Knoll Substation to the existing National Grid substation at Bicker Fen, Boston; and  Unlicensed Works within the existing National Grid Bicker Fen substation compound comprising up to two new ‘connection bays’ of electrical equipment required to connect the Electrical System to the National Grid. 1.6 The onshore Proposed Development Boundary for the Triton Knoll Electrical System is shown on the Works Plans( Application Document 2.1 and Figure 1.1 of Vol 3 Chapter 1: Onshore Project Description Application Document 6.2.3.1). Purpose of this Outline Plan

1.7 This outline Access Management Plan (AMP) forms part of the application for a DCO for the TKES and has been allocated application document reference 8.13 by TKOWFL. 1.8 This outline AMP is being provided in an indicative form to provide the Examining Authority and parties to the examination with an outline of the AMP to be submitted for any stage of the TKES in accordance with requirement 8 of the proposed DCO. 1.9 Its purpose is to provide outline proposals for access to the TKES for construction and operational purposes.

Scope of this Outline Plan

1.10 This outline plan relates to the onshore elements of the TKES for the proposed TKOWF, which include all construction access points to the cable

Triton Knoll Offshore Wind Farm Ltd Triton Knoll Electrical System

route and permanent access to the Intermediate Electrical Compound and Triton Knoll Substation. 2 TEMPORARY CONSTRUCTION ACCESS

Temporary Construction Compounds

2.1 Access to the cable route landfall, IEC and substation will be via the 26 Temporary Construction Compounds (TCCs) located along the Onshore Cable Route. These are illustrated on Figure 3.1 and will be accessed from the existing highways network. Access to a TCC will be designed to accommodate all types of vehicle required for that section of the works, including heavy goods vehicles (HGV’s) and any abnormal indivisible loads (AILs) required. 2.2 This outline plan identifies the location and indicative layout of the temporary access arrangements for each TCC. The drawings enclosed within this report relate to key locations along the route, together with generic layouts for the remaining accesses depending on the category of road that these TCCs will be accessed from, as summarised below:  Landfall;  Intermediate Electrical Compound;  Triton Knoll Substation;  Typical access from A road; and  Typical access from other roads. 2.3 Prior to construction, detailed layouts for each TCC would be confirmed by the Principal Contractor and agreed with the Highway Authority. Details of the access design will include the following areas:  Access point construction (i.e. crushed type 1 stone laid over terram membrane);  Fluming arrangements for any ditches at the side of the road;  Assessment of visibility splays at the access point and any mitigation required;  Extent of road-sweeping activity in vicinity of access point;  Construction routing for approaching and departing the site access;  Any temporary control measures to be applied to construction traffic using the access point (i.e. temporary speed limits); and

Triton Knoll Offshore Wind Farm Ltd Triton Knoll Electrical System

 Schedule of temporary signage to be used, and its location at the access and on the approach routes, in accordance with Chapter 8 of the Traffic Signs Manual (Traffic Safety Measures and Signs for Road Works and Temporary Situations, Part 1 Design, 20091),. 2.4 Draft outline drawings illustrating the potential layout of the temporary access arrangements for the above locations are provided at Figures 3.2-3.6. The ES assesses a worst case scenario for removal of vegetation to facilitate visibility at TCC accesses. In practice, removal of trees and hedgerows would be unlikely to be the first option for vegetation clearance, and alternatives such as hedgerow coppicing would be considered. If these measures were insufficient, traffic management measures would also be considered to ensure safety of access e.g. use of banksmen, temporary reductions in speed limit or temporary traffic lights. 2.5 The layout for each individual TCC access onto the public highway should be designed for the current level of traffic flows along the TCC frontage, as agreed with the relevant highway authority taking into account traffic flows from the committed developments, and the predicted level of turning movements and sizes of vehicles required to use the TCC during the construction period. The access design and layout should be produced in accordance with the ‘Design Manual for Roads and Bridges’ and the Highway Authority’s requirements. 2.6 The typical access arrangements provided for the TCC sites illustrate how they would accommodate all sizes of vehicles required to deliver specialist equipment and materials to the TCCs. 2.7 All TCC access arrangements would be designed to accommodate two-way traffic and, where appropriate, provide for standing vehicles clear of the through carriageway, sufficient to mitigate queuing on the highway. 2.8 The following table identifies the relevant outline access drawing appropriate to each TCC:

2.9 Finalised drawings, showing the full detail of access improvements, including measures to ensure safe access from the highway onto the Onshore Cable Route via the TCC locations, would be agreed as part of the detailed AMP through consultation with the Highway Authority as part of a section 184 Agreement..

Road Crossings

2.10 The Onshore Cable Route will cross public roads at a number of locations where a TCC is not proposed to be constructed, as illustrated at Figure 3.7. In these locations, HGVs will only cross the road while non-HGV traffic may

Triton Knoll Offshore Wind Farm Ltd Triton Knoll Electrical System

enter and exit the construction site. Methods of management of construction vehicles at each road crossing will be agreed within the Traffic Management Plan. 2.11 Draft outline drawings illustrating the typical layout of the temporary access arrangements for the above locations are provided at Figure 3.8. 2.12 Finalised drawings, showing the full detail of access improvements, including traffic management measures to ensure safe access across the highway between sections of the Onshore Cable Route, would be agreed as part of the detailed AMP through consultation with the Highway Authority.

3 PERMANENT ACCESS

3.1 The Intermediate Electrical Compound and Substation will require permanent access for regular maintenance purposes. The location of these is illustrated on Figure 3.1 and would be accessed from the existing highways network. 3.2 This AMP identifies the location and layout of each of the permanent access arrangements. Prior to construction, detailed layouts for each access would be confirmed by the Principal Contractor and agreed with the Highway Authority as part of a section 278 Agreement. TKOWFL will subsequently carry out the works under the DCO. 3.3 Draft outline drawings illustrating the layout of the proposed permanent access arrangements for the Intermediate Electrical Compound and Triton Knoll Substation are provided at Figures 4.1 and 4.2. 3.4 The layout for each individual TCC access onto the public highway should be designed in accordance with the ‘Design Manual for Roads and Bridges’ and the Highway Authority’s requirements. The drawings also illustrate how each access would accommodate all sizes of vehicles required to deliver specialist equipment and materials. 3.5 Finalised drawings showing the full detail of permanent access arrangements would be agreed as part of the detailed AMP through consultation with the Highway Authority.
