State OKs $854M plan to update Marcy-to-Albany power transmission line


An $854 million upgrade of a 93-mile electric power transmission line from Marcy to Albany County has won approval from the New York State Public Service Commission.

The Marcy to New Scotland upgrade Project is designed to speed the flow of electricity from upstate to high-demand markets downstate. The project is being developed jointly by LS Power Grid New York Corp. and the New York Power Authority. It involves replacing existing lines along the existing transmission corridor, as well as upgrades to the Marcy and Edic substations in Oneida County.

The project will replace aging and outdated H-shaped transmission towers, some as old as 60 years, with fewer monopole towers along the route, which in Oneida County includes Marcy and Deerfield, then through Herkimer, Montgomery, Schenectady and Albany counties. It dates back to 2012, when the Public Service Commission sought ideas from power companies to improve the link between hydropower generators in the North Country to the rest of the state.
