• SWS Development Update: John Rodger

• Q & A

Introduction: Pearse Murray : SPT Director SWS Summary

• Good progress being made on construction of phase 1. On programme to commission New Cumnock substation in 2015. • Discharge of planning conditions and conclusion of legal agreements for overhead line routes and substation sites taking longer than anticipated. • Pre-construction and contracting activities continuing in order to facilitate commissioning of Dunhill / Blackhill / Glenglass and Margree collector substations by end March 2017. • Contract placed for 132kV overhead line construction for stages 2 to 4 • Programme requires commencement of site work at Dunhill / Blackhill and Glenglass and OHL tree felling in Q3 2015. • Key risks to programme are discharge of consents, conclusion of wayleaves / leases and extensive construction activities at altitude over winter period. • 9 consented windfarms 14 consents in progress/not consented /refused - 481MW consented and 1011MW yet to achieve consents
