Niagara Mohawk Power d/b/a National Grid on Nov. 13 filed with the New York State Public Service Commission a Part 102 Report for its North Troy Bundle #13/#14/#16 115-kV Conductor Clearance Refurbishment Project.
As noted in the filing, the project requires the replacement of one structure and the installation of nine new intermediate structures on the Wynantskill-Reynolds Road #13, North Troy-Wynantskill #14, and North Troy-Reynolds Road #16 115-kV transmission lines.
The existing conductor would be transferred to the new structures, the company said, noting that the lines are located between the North Troy substation in the City of Troy, N.Y.; the Wynantskill substation in Wynantskill, N.Y.; and the Reynolds Road substation in South Troy, N.Y., a distance of about 11.8 miles.
The project is located in the towns of Brunswick and North Greenbush in Rensselaer County, N.Y. The company also said that the lines were built in 1931 and are generally supported by double-circuit, steel flex towers and lattice towers. The Tap-Sycaway Line, where installation structure 20A is proposed, is supported by double-circuit, single pole, wood davit arm structures. The company also noted that no major work has occurred to the lines since they were placed into service.
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, National Grid said. Timely completion of the work is essential to mitigate potential impacts to customer reliability and public safety, the company added.
All work associated with the project would be performed within existing rights of way (ROWs) owned by National Grid.
Among other things, the company said that project construction is proposed to begin in January 2019, and the target date for completion of the project is late spring 2019.
