The New York State Public Service Commission on Jan. 10 told National Grid that it will not require an investigation of the company’s proposed North Troy Bundle #13/#14/#16 115-kV Conductor Clearance Refurbishment Project.
The work proposed in the project located in the towns of Brunswick and North Greenbush, Rensselaer County, N.Y., has been reviewed, the commission said.
As TransmissionHub reported, Niagara Mohawk Power d/b/a National Grid on Nov. 13, 2018, filed with the commission a Part 102 Report for its project, which 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 in the filing, 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 company 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 also said that project construction is proposed to begin in January 2019, and the target date for completion of the project is late spring 2019.
National Grid spokesperson Patrick Stella on Jan. 11 told TransmissionHub that the permitted portion of the project is scheduled to start on Jan. 21, and to be complete in late February – weather and emergencies dependent.
"There will be additional maintenance work that will [be] completed that does not require Part 102 permitting but will continue until mid to late spring 2019," he said.
Project cost estimates were not available on Jan. 11.
