New York regulatory investigation not required for National Grid’s proposed 115-kV refurbishment project

The proposed reconstruction of National Grid USA’s 115-kV overhead electric transmission line in the towns of Amherst and Tonawanda in Erie County, N.Y., and the towns of Pendleton and Lockport in Niagara County, N.Y., will not require an investigation by state regulators.

The New York Department of Public Service provided such notice in a Sept. 30 letter to the company.

According to the company’s report on the Huntley – Lockport #36 115-kV conductor clearance refurbishment project, filed with the state Public Service Commission (PSC) on Aug. 1, Niagara Mohawk d/b/a National Grid is proposing to perform a refurbishment project on the T1440 Huntley-Lockport #36 115-kV line (main line) and the Huntley-Lockport #36 Ayer Road station 211 Tap (tap line).

The main line, which is about 21 miles long, begins at the Huntley substation in Tonawanda and ends at the Lockport substation in Lockport. The tap line is about 1.2 miles long and is entirely within Amherst, the company added.

The 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, the company said.

The line has been identified as having six areas within 22.2 miles that have potential substandard clearances and engineering analysis is still being performed to determine if all six areas actually have substandard clearances.

The project requires preparation of the Part 102 report because the line has a voltage of 65 kV or higher, the proposed work takes place over a distance of one mile or longer, the proposed work involves the installation of six new intermediate structures, and the installation of two replacement structures that will be at least 10 feet higher than the structures being replaced, the company added.

All project activities will take place within the existing managed right of way (ROW), the company said, adding that the proposed new replacement and intermediate structures for the project will consist of single wood pole and double wood pole structures that will either replace or be intermixed with the existing steel flex towers and square based lattice structures.

On the environmental resources evaluation, National Grid said that there are no long-term impacts anticipated as a result of the project, but short-term impacts associated with the disruption of ongoing farming activities may occur.

The company said it will attempt to minimize short-term impacts through scheduling and, where possible, coordinating construction activities with ongoing farm operations. Additionally, all work in areas of active agriculture will be done under best management practices in order to minimize the impact to agricultural lands.

Among other things, the company said no work is anticipated near regulated streams.

National Grid is a subsidiary of National Grid plc.
