No investigation required for proposed National Grid 115-kV refurbishment project in New York

The New York Department of Public Service (DPS) on Jan. 13 told National Grid USA that state regulators will not require an investigation of the company’s proposed DeWitt-Tilden #19 115-kV Line Conductor Clearance Refurbishment Project.

The DPS noted that the work proposed to the 115-kV overhead electric transmission facility, located in the towns of DeWitt, Lafayette and Onondaga in Onondaga County, N.Y., has been reviewed.

As TransmissionHub reported last November, Niagara Mohawk Power d/b/a National Grid filed a Part 102 report with the state Public Service Commission.

The line, which begins at the Dewitt substation in Dewitt and ends at the Tilden substation in Onondaga, is about 7.5 miles long and located on mostly single-circuit wood H-frame structures.

The project is necessary to provide system reliability to the electric 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 also said that similar to projects conducted in accordance with the 2010 NERC guidance document involving field conditions and facility ratings, National Grid adheres to a limited timeline to address substandard clearances to comply with New York ISO standards and guidelines related to facility ratings.

National Grid is a subsidiary of National Grid plc.
