The New York State Public Service Commission on Oct. 18 told National Grid that it will not require an investigation of the proposed construction of the Alabama Telegraph 115-kV Asset Condition Refurbishment Project.
The work proposed in the project located in the Town of Royalton, Niagara County, N.Y., has been reviewed, the commission said.
As TransmissionHub reported, Niagara Mohawk Power d/b/a National Grid recently filed with the commission a “Part 102 Report” for construction activities associated with an asset condition refurbishment project, which includes replacing 34 jurisdictional structures on the Alabama-Telegraph #115 115-kV transmission line (the 115 Line).
The project also involves installing one new structure on the 115-Line and replacing one jurisdictional structure on the Lockport-Mortimer #114, Telegraph Road Tap #115 115-kV Transmission Line (the 114 Line).
The 115 Line is located between the Alabama Junction Switch Structure and the Telegraph Road substation, a distance of about 4.7 miles, located entirely within the Town of Royalton, Niagara County, N.Y., the company added.
National Grid spokesperson David Bertola on Aug. 27 told TransmissionHub that the project’s estimated cost is $8.3m, and that if the project is approved, construction would begin in November. With that timetable, the project would be in service in April 2019, he said.
The company said in its filing that the 115 Line was built in 1931 and is a single-circuit transmission line. Due to severe pole deterioration, five structures were replaced in 2011 with wood pole H-frame suspension structures. The company added that from the Alabama Junction Switch to structure #12, the line is carried on wood pole H-frame structures and shares the right of way (ROW) with the Lockport-Mortimer #111 115-kV transmission line – carried on wood pole davit arm structures – and the Lockport-Mortimer #113 and #114 115-kV transmission lines – carried on double-circuit steel lattice towers.
From Structure #12 to the Telegraph Road substation, the #115 Line is carried on wood pole H-frame structures and shares the ROW with the #114 Line Tap to Telegraph Road, also carried on wood pole H-frame structures, the company said.
The 115 Line Refurbishment is a maintenance project that is necessary to provide system reliability to the electric utility end users. The existing 115 Line has reached or will soon reach the end of its useful life and timely completion of that work is essential to mitigate potential impacts to customer reliability and public safety, the company added.
