The Marcy to New Scotland Upgrade Project will improve electric transmission facilities within existing utility corridors. These upgrades will help relieve bottlenecks on the New York power grid, support renewable energy, replace aging infrastructure to improve reliability, and provide many other benefits to businesses and residents across New York State.
Nearly 100 miles in length, the project has a number of different components. Along much of its length, we’ll be replacing two aging sets of “H”-frame transmission towers with just one set of modern monopole structures that can move more electricity, more efficiently – in fact, the project along that segment will be able to carry more than four times the capacity of the existing lines. In other segments, we’ll be adding new monopoles carrying two new circuits together. The project also includes upgrades at several existing substations and the construction of two new, indoor gas-insulated substations using state-of-the-art technology. By using existing rights-of-way and today’s best technologies, we’ll minimize the impact on residents and communities.
