About the Project

New York State Electric & Gas Corporation (NYSEG) is in the planning stages of a significant, multi-year electric transmission system project, which we call the Livingston Transmission Enhancement (LTE) Project.

As part of our commitment to provide safe and reliable service to all our customers, NYSEG, in conjunction with our parent company Avangrid, is updating the electric transmission system in our service areas. While we are investing in upgrades to meet New York State’s energy goals and the community’s growing energy demands, we are working closely with our neighbors to ensure that all improvements are performed safely and with minimal disruption to the environment and the community.

Project Map

Project Scope & Benefits

The Project consists of the rebuild of approximately 18 miles of Line 934 (L934), a 115 kV transmission line running between the South Perry Substation in the Town of Castile in Wyoming County to the Meyer Substation in the Town of North Dansville in Livingston County, New York.

The Project proposes to rebuild approximately 9.4 miles of L934 the line parallel to the existing L934 centerline. This 9.4 miles of parallel centerline rebuild is broken into two segments.

  • The first segment is approximately 1.9 miles and begins at South Perry Substation until the line meets with the western boundary of Letchworth State Park.
  • The second segment is approximately 7.5 miles and begins at the eastern boundary of Letchworth State Park and continues until the existing L934 centerline and existing 230kV L87 centerlines diverge.

Through Letchworth State Park, no new structures or conductor will be installed; only maintenance and reinforcement of the towers is proposed in the Park.

The final approximately 6.7 miles proposes to rebuild L934 along a new center line that parallels existing L87 within an existing NYSEG right-of-way easement until terminating at Meyer Substation.

Regional Benefits 

  • Consists of "Local” Transmission System upgrades required to support New York’s energy goals. 
  • The Project would remove bottlenecks on the local transmission system and allow existing and projected future generation facilities to connect to the power grid. 
  • The Project would generate numerous ancillary economic benefits to our community partners. 
  • The most direct infusion to the local economy would come from employment opportunities associated with construction of the Project and of future generation facilities. Worker income would be spent in local communities on consumer goods and services such as housing, healthcare, and food, while property taxes would directly support the communities in which the Project is located. 
  • The Project is needed for NYSEG to continue to ensure electric generation deliverability and capacity throughout its Hornell Division. The Project also upgrades assets that are near the end of their useful life.

About the Permitting Process

NYSEG is actively developing the Project to avoid and minimize negative impacts to the community and the environment. Early Project planning efforts have included the completion of resource assessments to clarify important planning considerations such as streams and wetlands; soil characteristics; cultural resources; and sensitive plant and animal species. Active regulatory coordination, reviews and permitting efforts are under way for initial phases of the Project. NYSEG will seek reviews, consultations and/or permits from the following federal and state administrative agencies for the Project:

  • NYS Public Service Commission
  • U.S. Army Corps of Engineers
  • Federal Aviation Administration
  • NYS Department of Environmental Conservation
  • NYS Department of Transportation
  • Other permits as may be necessary
