About

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 Steuben Chemung Area Transmission Enhancement (SCATE) Project.

While making investments to improve system performance and update system assets to improve system resiliency, we are working closely with our neighbors to ensure that all improvements are performed with minimal disruption to the environment and the communities we serve.

Project Map

Project Scope & Benefits

The proposed transmission rebuild project includes:

  • Rebuild NYSEG’s 230kV Lines 68, 69, and 72 between Canandaigua, Stoney Ridge, Watercure, and Hillside Substations using single circuit steel H-frame & monopole structures with approximately 1.5 times larger conductor size and allowable capacity.
  • As a result of the known asset condition needs and the deliverability overloads requiring larger capacity conductors on the lines 68, 72, and 69, the recommended solution for all three are full rebuilds of the assets. The scope of work for each line is as follows:
    • Line 68 - Rebuild on a 65’ offset. No new ROW is anticipated for this solution.
    • Line 72 - Rebuild on a 65’ offset in existing ROW. Due to ROW congestion near Hillside Substation and anticipated outage restrictions, Line 72 will be rebuilt upgrading existing transmission towers and using new caisson foundation steel monopoles.
    • Line 69 - Due to ROW congestion near Hillside Substation and anticipated outage restrictions, Line 69 will be rebuilt upgrading existing towers and using new caisson foundation steel monopoles.

Regional benefits include:

  • 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 and future renewable generation facilities are located.
  • The upgrades would improve the reliability and resiliency of the entire transmission system, ensuring the maintenance of safe and reliable power distribution.

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
