N.Y. regulators to not require investigation of National Grid reconductoring project

The New York State Public Service Commission on April 16 told National Grid that it will not require an investigation regarding the company’s proposed construction of the General Electric-Geres Lock #8 115-kV Transmission Line Reconductoring Project.

The work proposed in the project located in the towns of Camillus, Geddes, Van Buren, Clay, and Salina in Onondaga County has been reviewed, the commission said.

According to the Feb. 19 Part 102 Report filed with the commission by Niagara Mohawk Power d/b/a National Grid, the company proposes to conduct the reconductoring and maintenance project along a section of the double-circuit line, which originates at the General Electric substation in Liverpool, N.Y., and terminates at the Geres Lock substation in Solvay, N.Y.

The portion of the line subject to the project is an approximately 7.1-mile portion between structure 455A in the Town of Salina and the Geres Lock substation, the company said, adding that that includes the replacement of 16 existing structures and the installation of one new intermediate structure.

Of the existing structures, the scope of work includes replacing the existing structures with 13 direct embed, double-circuit, 2-pole davit arm wood pole equivalent (WPE) suspension steel structures and three double-circuit, single-pole, steel davit arm deadend structures supported by concrete caisson foundation. The company added that the new intermediate structure would include the installation of one direct embed, double-circuit, 2-pole davit arm WPE suspension steel structure.

The line is supported by double-circuit, steel flex suspension towers, double-circuit, steel lattice suspension and deadend towers, double-circuit, steel, single-pole suspension and deadend structures (STR), as well as wood H-frame structures, the company said. The project does not include new or modified interconnection facilities or require any additional right of way (ROW) acquisition, the company said.

The project is necessary to improve the operating condition of the transmission line through replacement of assets, which includes reconductoring the segment of the line between Structure 455A and the Geres Lock substation, about 7.1 circuit miles, National Grid said. The proposed structure replacements are needed to meet the NESC clearance requirements, the company noted.

The line is about 8.23 miles long, the company said, adding that it originates at the General Electric substation in the Village of Liverpool, within the municipal boundary of the Town of Salina, proceeds west and south, crossing I-90 and I-690, and terminates at the Geres Lock substation in the Village of Solvay, within the municipal boundary of the Town of Geddes, N.Y.

The existing land use and/or groundcover conditions along the project corridor consist primarily of mowed utility ROW, wetland areas, and railroad corridors, National Grid said, noting that the adjacent land use in the project area includes industrial, commercial, residential, recreational, and open space – Onondaga Lake Park – as well as undeveloped land.

National Grid said that while the project traverses the Erie Canal, no impacts to the canal are anticipated. The line runs parallel with, and crosses, Interstate Route 90, and crosses Interstate Route 690, New York State Route 57 – Oswego Road – as well as State Fair Boulevard, Armstrong Road, Morgan Road, along with numerous lower traffic roads, the company said.

National Grid noted that it owns the ROW for the project.

The line was originally built in 1914, with some material upgrades in 1957 and taps to the Village of Solvay added in 1964, the company said.

Among other things, the company said that project construction would be eligible to begin as soon as all permits and approvals are obtained from the commission. The target date for completion of the project is spring 2020, the company said.
