Project Description

 

National Grid's Gardenville - Dunkirk 141/142 Transmission Rebuild Project is a transmission line project that will rebuild aging electric transmission lines in Erie County's Southtowns region. The rebuild will focus on the northern 20 miles of existing 115,000 volt (or, 115kV) electric transmission lines, traversing the communities of Angola, Evans, Hamburg, Blasdell, Lackawanna, and West Seneca, in Erie County, New York. Once constructed, the newly rebuilt transmission lines will provide enhanced electric reliability for the Western New York region.

Project Benefits

  • The project will replace aging electric infrastructure. The existing lines were originally built in the 1930s and are nearing the end of their useful lives. The project will replace the existing infrastructure with modern technology.
  • With the installation of larger conductor (wires), electric power transfer capabilities along these lines will be improved to better meet the area's current and future electric load needs. System reliability will also be enhanced by building to the most current codes.
  • Rebuilding the transmission lines provides for a cost-effective solution for the continued long-term maintenance and operation of the transmission lines.

Permitting

Permitting Update

In May 2022, the Public Service Commission (PSC) approved National Grid's Environmental Management and Construction Plan (EM&CP). 

What is the EM&CP?

The EM&CP includes plans and specifications for environmental protections and construction of the Project. The main EM&CP document includes information on conditions from the PSC that National Grid must meet during Project construction. Appendix A of the EM&CP includes the proposed Plan and Profile construction drawings, which includes details such as Project access and structure locations. Various other appendices detail plans for environmental protection and communications protocols, among other topics.

The community, including affected landowners, will receive a Construction Commencement Notice before the start of construction. Construction is anticipated to start in Fall 2022.

Article VII

The Article VII process involves an evaluation of all potential impacts from the Project and will include a detailed environmental impact assessment. Other agencies, like the Department of Agriculture and Markets, the Department of Environmental Conservation, and the Office of Parks, Recreation, and Historic Preservation, are parties to the Article VII process. 

Other Agency Permits

Permits from other agencies are also required before construction can start. 

  • The U.S. Army Corps of Engineers will issue a permit under the Clean Water Act for construction activities in any waters under its jurisdiction (these typically include wetlands in upstate New York). 
  • The Federal Aviation Administration (FAA) reviews the project and makes determinations regarding structure heights and proximity to air fields. 
  • New York State Department of Transportation (DOT) and local highway permits will also be required for various Project road crossings.
  • National Grid will work with the railroad company on obtaining an occupancy agreement and any other permits needed for construction along the railroad corridor.

Public Involvement and Comment

The permitting process includes opportunities for public involvement and comment from permitting through construction. To contact National Grid with a question or comment, click the "Contact Us" link above.

Project Map

Project Segments

The Project is comprised of 6 segments, each with a unique transmission corridor and construction plan. Below are descriptions of each segment. For segment locations and visualizations, please see the Project Map above.

Segment 1 (Mile 0 to 8): Located in the Towns of Evans and Hamburg, Segment 1 generally involves the removal of existing double-circuit 115kV lattice structures and associated lines (wires), along with the removal of an existing 34.5kV sub-transmission line in the corridor. These structures will be replaced with a triple-circuit monopole structure that will house two 115kV transmission lines and one 34.5kV transmission line. Due to existing physical constraints, there are two exceptions to this general design:

  • The first structure outside of the North Angola Substation will be reused.
  • For one mile between South Creek Road and Lakeview Road, a new double-circuit 115kV monopole structure will replace the existing lattice structure. The 34.5kV sub-transmission structure will remain in place.

Segment 2 (Mile 8 to 11.6): Located in the Town of Hamburg, the existing double-circuit 115kV lattice structures and associated lines will be removed and replaced with a double-circuit 115kV monopole structure, which will be built approximately 38 feet to the east of the existing lattice structure. For approximately 3.4 miles between Pleasant Ave and Camp Road, the new 115kV facilities will swap locations with the existing 34.5kV sub-transmission line, which will be rebuilt where the existing lattice structure now stands.

Segment 3 (Mile 11.6 to 15.4): Segment 3 is located in the Town of Hamburg and generally involves the removal of existing double-circuit 115kV lattice structures and associated lines. The structures will be replaced with a new double-circuit 115kV monopole structure on the existing centerline of the transmission lines. Exceptions to this general design include:

  • For an approximately .2-mile span near Big tree Road, the existing 115kV double-circuit lattice structure and 34.5kV sub-transmission structure will be removed and replaced with a new triple-circuit monopole structure, housing two 115kV lines and one 34.5kV line.
  • Some structures will not be removed and will instead have the existing conductor (wires) replaced with new conductor. These structures are located near the FedEx distribution facility and south of the Mile Strip Expressway.
  • West of Seneca drive, three structures would be rebuilt in the general design, but the centerline will be moved approximately 38 feet to the west.

 

Segment 4 (Runs east to west. Then mile 15.3 to 16.9): Located in the Town of Lackawanna, the existing double-circuit 115kV lattice structures and associated wires would be removed and not replaced in the transmission right-of-way (ROW). The new structures would instead be built in the Segment 4 Bypass ROW, described below.

Segment 4 Bypass: The Segment 4 Bypass is located in the Towns of Hamburg and Lackawanna, and will be built using existing an existing transmission right-of-way. A new double-circuit 115kV monopole structure will be built to the west of existing double-circuit 115kV lattice structures.

Segment 5 (Mile 16.9 to 18.9): Located in the Towns of Lackawanna and West Seneca, the existing single-circuit 34.5kV lattice structure would be removed and replace with a double-circuit 115kV monopole structure. Also, the existing double-circuit 115kV lattice structure would be removed and replaced with a single-circuit 34.5kV sub-transmission pole structure.

Segment 6 (Mile 18.9 to 20.3): Located in the Town of West Seneca and terminating before the Gardenville Substation, Segment 6 generally involves the removal of existing double-circuit 115kV lattice structures and replacing them approximately 45 feet west of the existing centerline with a double-circuit 115kV monopole structure. The final .4 miles of the project (near Meyer Road, State Highway 400, and Center Road) would involve reconductoring (replacing wires) on existing lattice structures.


Construction Process

Rebuilding an electric transmission line involves a variety of activities set out in phases. Below are sample descriptions and photos; actual construction sequencing, methods, and materials will vary.

1. Site Preparation:
The first phase of site preparation and construction is tree and brush clearing. Clearing allows construction crews to build access roads and remove any trees that are in danger of falling into the transmission lines. Marshaling yards will be established to house materials and construction crews.

2. Environmental Controls:
Next, environmental controls would be installed to mitigate construction impacts to the area. These can include matting, silt fence, concrete washouts, among others.

3. Transmission Line Rebuilding:
The next phase would be transmission line rebuilding, where foundations are poured, structures are spotted and erected, and new wire is strung and energized. Old structures would be removed from the transmission right-of-way. This work would be done with a variety of equipment, including cranes and other heavy equipment.

4. Restoration:
The final phase of construction is ground surface restoration, in which the construction area is restored to the condition it was in before construction.
