Project Update

Northern New York Priority Transmission Project, US [free access]

May 13, 2021

Developer: Yet to be decided

 

Project details and status: The proposed Northern New York Priority Transmission Project (NNYPTP) is a major transmission line rebuild, which will harden the resilience of New York's power grid and accelerate movement towards meeting New York State's clean energy goals.

 

In October 2020, the NNYPTP was identified by the New York Public Service Commission (NYPSC) as a priority transmission project that should move forward expeditiously under New York's Accelerated Renewable Energy Growth and Community Benefit Act, which is aimed at improving the siting and construction of large-scale renewable energy (RE) projects in an environmentally responsible and cost-effective manner.

 

In April 2021, the New York Power Authority (NYPA) announced the approval of the NNYPTP. NYPA’s authorisation paves the way for engineering and planning work to begin in preparation for the project's environmental review and approval process through the NYPSC.

 

The scope of work comprises rebuilding about 100 miles (161 km) of transmission lines by replacing aging wood H-frames with steel poles primarily within existing transmission corridors. The work will also include replacing or upgrading about 10 substations along the project path.

 

The project will involve the replacement of the existing transmission line in the St. Lawrence, Franklin, Clinton, Lewis, and Oneida counties. This is needed to both improve the resiliency of the New York state electric grid and also to efficiently transport renewable power to high demand areas of the state.

 

The project will support NYPA’s Vision 2030—a strategic plan focused on helping the state meet its energy targets in establishing a zero-carbon emission energy system by the year 2040.

 

Construction of the project is expected to commence in the third quarter of 2022 and to be in-service by the end of 2025.
