Faw Side Wind Farm Grid Connection Routeing Consultation Document September 2020 BASIC ELEMENTS 1.1 SP ENERGY NETWORKS BRAND, POSITIVE VERSION 1 The SP ENERGY NETWORKS brand is composed of two main elements - the symbol and the logotype. The integrity of the brand composition must be preserved in all applications in order to insure consistency of design and brand expression across a wide array of media. Only two configurations are permitted: 1 SP Energy Networks brand 2 Horizontal version of the brand The SP ENERGY NETWORKS brand must always be 2 the first choice. If this configuration does not suit the layout, the horizontal version should be used. Altering the positions or proportions of the brand elements is strictly forbidden, as is their combination with elements that are not permitted by this manual. Anyone seeking to reproduce the SP ENERGY NETWORKS brand must request a digital file from ScottishPower Group Internal Communications. ScottishPower Group Internal Communications must, in turn, approve the use of either of these two versions.

Introduction R1.1 Purpose of the Report R1.1.1 This document has been prepared by The Environmental Dimension Partnership Ltd (EDP) and Stantec on behalf of SP EnergyNetworks (SPEN) and relates to the identification and appraisal of route options for two new 132 kilovolts (kV) overhead lines (OHL) supported on wooden poles to connect the proposed Faw Side Community Wind Farm to the transmission grid in the south of Scotland, hereafter referred to as the ‘Proposed Development’. R1.1.2 This report explains the background to the proposal, provides a description of the proposed grid connection and sets out the methodology for routeing the new OHL. It presents the findings of the environmental baseline and an evaluation of the route options, culminating in a description of the ‘preferred route’ for the connection. The report also sets out the process for consultation with stakeholders and other interested parties and how this will be undertaken, providing the opportunity for interested parties to comment on the preferred route and inform the next stages of the design and assessment process. R1.2 Need for the Project R1.2.1 There is a need to connect the proposed wind farm to the transmission grid in southern Scotland. This is to be done via two separate OHLs. When a wind farm developer applies for a connection via National Grid, within the Scottish Power Transmission (SPT) license area, SPT, as the transmission licence holder, is obliged to provide such a connection. As with all grid connections of this type, the initial premise is that these will be provided through OHLs. In broad terms, the lines will run from the substation at Faw Side Community Wind Farm making a direct connection to the steel lattice towers on the existing transmission line known as the ‘V-Route’, which runs from Melrose to the border with England. R1.2.2 The location of the key elements of the electrical infrastructure and the wind farm are illustrated on Figure 1.
