Smart Path Connect

Smart Path Connect Transmission Project

Smart Path Connect, a project being developed in partnership with National Grid, is part of a comprehensive portfolio of transmission upgrades being undertaken across the state to support New York’s clean energy goals. Together, the projects will enable the flow of an additional 1,000 megawatts (MW) of clean, renewable energy across New York State.

Smart Path Connect will rebuild approximately 100 miles of transmission by replacing aging wood H-frames with steel poles almost exclusively within existing transmission rights-of-way and replace or upgrade approximately 10 substations along the project path.

Project Benefits:

  • Increases power flow capacity
  • Improves asset condition
  • Increases transmission system resilience to severe weather events
  • Creates longer spans between poles
  • Uses fewer poles and less land 
  • Reduces transmission system congestion
  • Creates hundreds of local jobs during construction

New York’s Green Energy Superhighway

Smart Path Connect is critical to realizing the full potential of renewable energy in the Northern New York area and meeting the New York Climate Leadership and Community Protection Act (CLCPA) targets.

The project complements and expands upon both NYPA’s Smart Path which is currently under construction and is anticipated to be completed in 2023, and the Marcy to New Scotland Transmission Upgrade Project which NYPA is undertaking with LS Power Grid New York in the Mohawk Valley and Capital Region.

With the addition of the Smart Path Connect, these investments will establish a continuous 345 kilovolt (kV) transmission path that greatly expands the deliverability of renewable power from northern and western regions to high demand areas across the state. The transmission work being undertaken by NYPA is also consistent with the Power Authority’s new VISION2030 Strategic Plan which is focused on helping New York meet its clean energy goal of having a zero-carbon emission energy system by 2040.


The Accelerated Renewable Energy Growth and Community Benefit Act signed into law by Governor Andrew M. Cuomo on April 3, 2020, provides for the “timely and cost-effective construction of new, expanded and upgraded distribution... to achieve clean energy and environmental targets established in the Climate Leadership and Community Protection Act.” The Act directs the Public Service Commission (PSC) to identify projects for which "there is a need to proceed expeditiously to promote the State's public policy goals."

On July 2, 2020, NYPA submitted a petition to the PSC for the development of the Smart Path Connect (formerly the Northern New York Priority Transmission Project) which was approved by an order dated October 15, 2020. The Project is a multi-faceted project that includes completion of the second phase of NYPA’s 86-mile Smart Path Moses-Adirondack rebuild, rebuilding approximately 45 miles of transmission eastward from Massena to the Town of Clinton, known as the Northern Alignment, and rebuilding approximately 55 miles of transmission, in partnership with National Grid, southward from Croghan to Marcy, known as the Southern Alignment. The project will also rebuild and expand several substations along the impacted transmission corridor. The work falls almost exclusively within existing transmission rights-of-way.

Why is this work being done? 
The wooden structures currently in place for most of the project length and related infrastructure are aging and vulnerable to harsh weather. Maintenance is more frequent and difficult because compatible materials are not readily available. Additionally, most of the work will involve upgrading the existing lines from 230kV to 345kV, increasing power flow capability.  

Are there any other benefits of this work? 
Rebuilding the line so it is all on steel structures will reduce maintenance and improve resiliency, allowing for a more efficient, reliable flow of electricity. Use of local trades and businesses during design, permitting & construction. Increased activity at restaurants, hotels and suppliers. 

Has any thought been given to placing the new line underground? 
Placing the line underground, much of which is rock, is not technically or economically feasible. 

How can the public get involved?  
The public will have many opportunities for providing input through the New York State Public Service Commission’s (PSC) Article VII environmental review process that is required for the rebuilding. NYPA and National Grid will make all project applications and related information publicly available. The New York State Public Service Commission (PSC) reviews input from public, stakeholders and regulatory agencies. 

Have environmental impacts been factored into the Design?
Yes. The proposed steel monopoles have a smaller footprint on the land than the current wooden H-frames. Approximately 50 percent fewer structures will be needed due to longer spans between monopoles.

What is the schedule for work and when will it be completed? 
Licensing and engineering studies began in 2020 and will continue through 2021. Construction to rebuild the line is expected to begin in 2022 and end in approximately 2025.

NYPA and National Grid hosted a series of public meetings or webinar events for soliciting community input on the Project.

The Public Meeting Webinars (held in April 2021) were thirty-minute presentations, followed by a Q&A session. Participants had the opportunity to view preliminary designs, ask questions and offer comments. 

The webinars were recorded and will be posted to this webpage at a later date.

Presentations focusing on the Northern Alignment from Massena to Clinton were hosted on Tuesday, April 6 at 2 pm, and Thursday, April 8 at 6 pm. 

Presentations focusing on the Southern Alignment from Croghan to Marcy were hosted on Thursday, April 8 at 2 pm, and Tuesday, April 13 at 6 pm.



NYPA and National Grid will pursue certification and regulatory review through the New York Public Service Commission’s Article VII Process. The Article VII process requires a full environmental review of any major transmission facility’s siting, design, construction, and operation in New York State.

The project will comply with all applicable state and federal laws. Certificates and permits will be sought from the appropriate agencies including the New York State Public Service Commission and the U.S. Army Corps of Engineers with coordination with the New York State Department of Environmental Conservation, Department of Agriculture and Markets and the NYS Parks Recreation and Historic Preservation Office. 

The Public Service Commission assigned case number 21-T-0340 to the project. Here’s a link to the filed documents list:
