temporary period of up to 5 years, of a new electricity double circuit transmission tower approximately 52 metres high at a position located between tower numbers 3 and 4 along the existing 220 kV Donard test (non energised) overhead line (OHL), and it will be used as part of an uprate trial along this test OHL, the permanent replacement of the existing single circuit tower number 3 with a new, upgraded single circuit tower of similar design and dimensions, approximately 35m in height, additional ancillary temporary development includes 3 no temporary pole structures, 2 no line puller / tensioners located either side of the proposed tower, a temporary landmat access road approximately 400m long and 5m wide, hardstanding areas with a combined area of approximately 840 sqm, a self contained pre fabricated site office of area 291 sqm, fencing and all other ancillary site works. The line will remain non-energised for the duration of the trial and following the conclusion of the development
