New York regulators find deficiencies in National Grid report regarding 115-kV refurbishment project

New York state regulators on Dec. 2 told Niagara Mohawk d/b/a National Grid USA that its Part 102 Report submitted in relation to its Stoner-Rotterdam #12 115-kV Transmission Line Conductor Clearance Refurbishment Project is deficient.

The state Department of Public Service (DPS), on behalf of the state Public Service Commission (PSC), noted that it will not start its review of the report until the deficiencies have been remedied and will have 60 days to review the report once it is appropriately fixed.

Part 102 of the DPS regulations establishes filing requirements for reports to install non-Article VII electric transmission facilities.

The review of the company’s report is ongoing, the PSC said, adding that the deficiencies involve a need to address residential areas, as several areas adjacent to the right-of-way (ROW) appear to be residential, as well as a need to detail the work proposed in agricultural districts, since several intermediate structures are located in those districts.

The PSC further noted that while not required for completeness, staff requests certain information to progress its review, including the age of the Stoner-Rotterdam #12 line, when the final engineering analysis will be completed, and a description of why the proposed pole types were chosen for the project.

According to the company’s Nov. 14 report, it proposes to do a refurbishment and maintenance project on the T5800 Stoner-Rotterdam #12 115-kV line, which begins at the Stoner substation in Johnstown, Fulton County, N.Y., and ends at the Rotterdam #12 located in Rotterdam, Schenectady County, N.Y.

The line consists mainly of double-circuit steel flex towers and is about 23.1 miles long.

The project is needed 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 line has been identified as having 28 areas with substandard clearances, the company added, noting that due to the rigid timeline to remedy a potential safety issue, National Grid is submitting the Part 102 Report assuming that 13 intermediate structures and 19 floating dead ends will need to be installed. This will ensure that once the engineering analysis is complete, National Grid will have obtained the necessary approvals to correct the substandard clearances and mitigate potential safety concerns.

The project will be done within National Grid’s existing ROW and no new property rights are required, the company added.

Among other things, National Grid said it is consulting with the state Department of Agriculture and Markets regarding the potential impacts to agricultural land with respect to the project.

National Grid is a subsidiary of National Grid plc.
