What will the poles look like?
Most people are familiar with the steel, self-supporting lattice-style tower structures, many of which were built during the 1950s and 1960s. Lattice-style transmission structures, although still in operation today, are generally not used in new construction. Today, we use a variety of tower and structure designs that are considered more aesthetically acceptable and leave a smaller footprint. For 345-kilovolt lines, we use either single-pole steel structures or wood H-frame structures. Factors such as cost, engineering, and the surrounding area dictate the type of structure. The type of steel may be a galvanized (silver) finish or a weathering finish which turns a brownish color over time. We will recommend a type of structure in our application to the PSC and share our recommendation with the public prior the application being submitted.
