Steuben Schuyler Update (SSU) West is comprised of Transmission Lines 723 and 953. These lines are located in NYSEG’s Hornell Division and Elmira Division. Line 953 travels 5.3 miles connecting the Bennett Substation to the Spencer hill Substation. Line 723 travels 15.1 miles connecting Spencer Hill substation to the Bath substation.

The assets are beyond their useful lives. For reference, the average age of the conductor on these lines is roughly 35 years old and the lattice towers are approximately 36 years old.

Upgrade Project Scope Includes:

SSU West, including the Bennett Substation, involves replacing existing lines with updated conductors built on H frame structures. This update will address asset condition concerns, deliverability constraints, and provide updated infrastructure components which are crucial for strengthening and modernizing the current electrical power grid.

Regional benefits include:

• Consists of "Local” Transmission System Updates 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 Project is needed for NYSEG to continue to ensure electric generation deliverability and capacity throughout its Elmira and Hornell Divisions. The project also Updates assets that are near the end of their useful life.

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
