The New York State Public Service Commission (PSC) on Jan. 13 told National Grid USA that it will not require an investigation of the company’s proposed Whitehall-Blissville #7 Line Conductor Clearance Refurbishment Project.
The work on the 115-kV non-Article VII electric transmission facility through the Town of Whitehall, Washington County, N.Y., has been reviewed, the company said.
As TransmissionHub reported, the line originates at the Whitehall substation in the Town of Whitehall and terminates at the Blissville substation in the Town of Poultney in Rutland County, Vt.
The line, which was built before 1973, runs for about six miles within New York before crossing the border into Vermont, where ownership transfers to the Vermont Electric Power Company (VELCO), Niagara Mohawk Power d/b/a National Grid said in a November 2016 Part 102 Report.
The maintenance project is necessary to provide system reliability to the electric utility end users, as well as provide for public safety in areas where structure replacement or other methods are used to mitigate substandard clearances and maintain thermal ratings, the company said.
As part of the project, National Grid said that it proposes to replace five structures and replace/relocate one structure to adhere to certain conditions. The project area traverses through agricultural areas and is adjacent to one residential property, the company said, adding that the line crosses U.S. Route 4 and State Route 21, along with multiple lower traffic roads. National Grid said that it owns the right of way (ROW) for the project.
Noting that the existing line is generally supported on single circuit wood H-Frame structures, the company said that the proposed new structure replacements/installations for the project would consist of wood H-Frame and three wood pole deadend structures.
