In 2019, LS Power Grid New York, together with the New York Power Authority, was designated by the NYISO through a competitive solicitation to construct, own, and operate the Marcy to New Scotland Upgrade Project.
Designed to address bottlenecks that limit the flow of electric power across New York State, LS Power Grid New York’s innovative solutions will greatly enhance the capacity of existing lines. Nearly 100 miles in length, the Marcy to New Scotland Upgrade Project has a number of different components, each designed to provide an efficient, low-cost solution.
Along most of its length, LS Power Grid New York will replace two aging sets of “H”-frame transmission towers with just one set of modern monopole structures that can move more electricity, more efficiently – the project along that segment will be able to carry more than four times the capacity of the existing lines. 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, LS Power Grid New York will minimize the impact on residents and communities.
