NYES Will Improve Energy Flow & Reliability With Minimal Community Impacts


New York Energy Solution (NYES) was selected from among competing proposals by the New York Independent System Operator (NYISO) in April 2019 as the preferred plan to modernize and upgrade the energy transmission network from Schodack in Rensselaer County to Pleasant Valley in Dutchess County.

On October 18, 2019, we submitted our application for a Certificate of Environmental Compatibility and Public Need under Article VII of the New York State Public Service Law. Our application has been given Case Number 19-T-0684.

Our planned upgrades will take place on an existing 54.5-mile utility corridor and on utility-owned land, and will permanently eliminate approximately 230 existing transmission structures, all while:

  • Alleviating energy bottlenecks;

  • Allowing for greater flow of clean energy from upstate generators;

  • Improving the reliability and resiliency of the transmission system.

Estimated Timeline

2019-2021:    Permitting

2021-2023:    Construction

End of 2023:  Project complete, improved transmission infrastructure in service.

Project Route

Transco+NYES_Generaljustmap copyFINALV2.png

Our work will stretch 54.5 miles through portions of Rensselaer, Columbia, and Dutchess counties, beginning in Schodack in the north and ending in Pleasant Valley in the south. Work will take place entirely in the existing transmission corridor and on utility-owned land in the towns of Schodack, Stuyvesant, Stockport, Ghent, Claverack, Livingston, Gallatin, Clermont, Milan, Clinton, and Pleasant Valley

Between Schodack and Claverack, we will:

  • Build a new 345 kV switching station on utility-owned land in Schodack;

  • Remove 80-year-old lattice transmission structures along approximately 22 miles of the existing utility corridor;

  • Install new, double circuit monopole transmission structures, with an average height increase of 10 feet, that will carry an existing 115 kV line and a new 345 kV line. One existing 115 kV transmission line will be permanently retired.

  • This portion of the project will require 15 more transmission structures than are currently in the corridor.

Between Claverack and Pleasant Valley, we will:

  • Rebuild an existing switching station on utility-owned property in Claverack;

  • Remove 80-year-old lattice transmission structures, which sit in side-by-side pairs along approximately 32 miles of the existing utility corridor;

  • Install a single row of new, double circuit monopole transmission structures, with an average height increase of 10 feet, to carry a new 345 kV line and one existing 115 kV line. Three existing 115 kV lines will be removed;

  • Eliminate 253 transmission structures along the main corridor;

  • Upgrade one existing section of the 2.2-mile Blue Stores tap line in the Town of Livingston, replacing the existing H-frame structures with an equal number of new H-frame structures with an average height increase of 15 feet. The existing 115 kV line will remain on the new structures.

  • Construct a capacitor bank station on utility-owned property off Van Wagner Road, approximately 0.8 miles northwest of the Pleasant Valley Substation. The location is shielded by a wooded embankment and adjacent to the existing utility corridor. Six existing lattice transmission structures in the corridor near the capacitor bank station will be replaced by three new double-circuit monopole structures, with height increases ranging from 35-65 feet. An additional five new monopole structures will also be built within the corridor adjacent to existing lines to carry a new 345 kV tap line between the capacitor bank station and the Pleasant Valley Substation. These structures will range from 120-175 feet in height, with just one structure reaching 175 feet. Like all of our project, this work will take place entirely within existing utility corridors and on utility-owned property.

[Please Note: Structure numbers are preliminary, pending final engineering]

NYES Benefits

  • Modernizes aging infrastructure.

  • Stays within the existing utility-owned corridor and on utility-owned land.

  • Streamlines the utility corridor with a new structure design, and permanently eliminates approximately 230 structures.

  • Alleviates energy bottlenecks, allowing for the efficient flow of clean energy resources from Upstate New York in support of the New York State Climate Leadership and Community Protection Act, which calls for 70% of New York State’s electricity to come from renewable sources by 2030.

  • Improves the reliability and resiliency of the transmission system.

  • Generates additional annual tax revenue for host communities and provides jobs during the approximately two-year construction period.

Modernization Is Needed

Studies performed by the New York independent System Operator (NYISO) and the New York Transmission Owners in 2012 confirmed the need for transmission upgrades to relieve congestion in the grid, especially at times of peak power demand, and to help the state achieve greater facilitation of renewable sources. The NYISO, the organization responsible for managing New York’s electric grid and its competitive wholesale electric marketplace, in 2016 sought proposals from developers to address the needs identified by the PSC under the Public Policy Transmission Planning Process. New York Transco submitted a proposal that included significant stakeholder feedback and, in April 2019, NYISO selected NYES for the Hudson Valley segment of the transmission upgrades

NYES Offers Lowest Cost, Best Outcomes

NYISO determined NYES will have the lowest cost per megawatt generated, the greatest reductions in carbon dioxide generation, and, according to the executive summary of the NYISO decision, the “most resilient foundation and structure design, resulting in significant benefits to the operability of the transmission system during extreme weather event.”

NYES is Committed to Listening

NYES is committed to stakeholder engagement at each stage of the project’s process. In fact, our plan incorporates stakeholder feedback expressed during public meetings and in the public record from years past, and is an example of the team’s focus on local first. We will continue to work closely with community leaders, advocacy groups, regulatory agencies, and individual property owners and residents throughout permitting and construction phases.
