Moses-Adirondack Smart Path Reliability Project

Smart Path: Rebuilding an aging transmission line

NYPA is planning to rebuild 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.

Reforming the Energy Vision: Building a cleaner, more resilient, and affordable energy system for all New Yorkers. #REV4NY

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.

Estimated Schedule:

2020: Start of Construction Expected
2023: Completion of Construction Expected
