  • Visual Simulations THE NORTHERN PASS SMThe Northern Pass Transmission Project About the Visual Simulations Factors to Consider when Viewing the Visual Simulations This booklet contains visual simulations of what The Northern Pass transmission line will look ➤ Weather conditions: Landworks takes photographs for the visual simulations on days when like from locations where people would potentially see it from. They were produced by LandWorks, it’s not rainy, when they know they would be able to see the structures from the chosen vantage a landscape architecture and planning firm out of Middlebury, VT, using sophisticated and point. The day could be overcast or crystal clear, which is reflective of the changeable weather industry-accepted software and software methodologies. conditions in New Hampshire. For each vantage point included in this booklet, we’ve provided a “before” image of what the view ➤ These are static views: Note that the view simulations are static images; the viewer is fixed on looks like today, and visual simulations showing what the view would look like with the inclusion of the objects presented in the photograph. This is not reflective of how you would experience these The Northern Pass transmission line using two typical industry designs: a) lattice transmission struc- views in nature, when you might be turning your head, driving, walking along a trail, etc. tures; and b) monopole transmission structures. ➤ Vantage points: Visual simulations present a sense of what the project will look like from one Photographs were taken using a 50 to 55-milimeter lens, which registers similar to what the human specific location, at one point in time. If you were to go 50 feet in another direction, you might eye sees. Because the eye acknowledges a 120- to 160-degree “cone of vision,” Landworks tends to not see the project at all, or you might see it more directly or in a different light. add a little more to the image on the left and right sides to provide a more accurate, panoramic view. Most Common Structure Heights for The Northern Pass In LandWorks’ experience, these visual simulations tend to look very close to (or exactly the same as) The anticipated height of most Northern Pass transmission structures is as follows: what the project will actually look like from these vantage points once built. ➤ For the new right of way in the North Country, from the Canadian border to Groveton, NH, The goal of the visual simulations is not to make the project look good or bad, but to provide an the most common structure height will be 85 – 90 feet. objective perspective and sampling of what the project will look like from as many different vantage points as makes sense.

Today, the majority of the existing transmission structures in these rights of way are 45 to 75 feet tall. The majority of these existing lines operate at a voltage of 115 kV alternating current (AC). The Northern Pass will construct lines that operate at voltages of +/-300 kV DC and 345 kV AC. These higher voltages require greater height and separation for safety.
