Moses-Adirondack Smart Path Reliability Project
Smart Path: Rebuilding an aging transmission line
Work has resumed on the Smart Path project, a vital transmission infrastructure project to rebuild and strengthen the Moses-Adirondack transmission lines. In coordination with New York State and other regional partners, NYPA identified a number of essential generation and transmission projects and associated construction, including the Smart Path project, that can safely continue using additional precautions against the spread of the COVID virus.
Through an Incident Command Structure, NYPA will continue to monitor the pandemic and make adjustments to these precautions as necessary.
About the Smart Path project:
NYPA is rebuilding its 86-mile-long Moses-Adirondack transmission line. Though consistently well-maintained, the line is over 70 years old and has exceeded its service life. Rebuilding the line will lead to long-term benefits and support future upgrades in voltage, which would allow for greater transmission of energy from renewable sources developed in Northern New York.

Rebuilding NYPA's Moses-Adirondack transmission lines: 86 miles long, the line runs from the switchyard at NYPA’s St. Lawrence-Franklin D. Roosevelt Power Project in Massena to the Adirondack Substation in Croghan.
The lines were built in 1942 and have exceeded their service life. The MA1&2 lines are essential for system reliability and system restoration (blackstart). Plan includes the removal of the old wooden H-frame structures and a rebuild with modern steel monopole structures.
Licensing and engineering studies began in 2015 and will continue through 2019.
Schedule (subject to change):
2020: Start of Construction
2023: Completion of Construction
