We’re proposing a rebuild and modernization of the Wright Avenue and Clark Street Substations, which will provide increased reliability, capacity, and resiliency for Auburn, Aurelius, Fleming, Springport, and Union.

The Wright Avenue project addresses critical capacity and reliability issues at the aging substation in Auburn, Cayuga County. Originally built in 1953, it faces thermal overloading, voltage regulation challenges, and contingency risks impacting 2,500 direct customers and thousands more in the local sub-transmission network. Serving Disadvantaged Communities and potential Environmental Justice Areas, the project includes a full substation rebuild to support 8.6 MW of new load requests, 35% from commercial heat pump installations and 65% from economic development. This investment resolves reliability and asset condition concerns, enhances system resilience, and enables future load growth in underserved areas.

The Clark Street and Endicott Railway substations, located in Endicott, NY, are approximately seven miles west of Binghamton and one mile apart. The Clark Street substation, built in 1942, serves 4,300 customers, while the Endicott Railway substation, built in 1940, serves 1,800 customers within a designated Disadvantaged Community Area. Both stations have aging infrastructure which is over 83 years old and well beyond its expected service life, raising concerns about reliability and safety.

The project involves a comprehensive rebuild of the Clark Street substation and the decommissioning of the Endicott Railway substation, addressing these concerns and facilitating future load growth in underserved areas.

The NYSEG Distribution Load Relief Program was established to identify and address capacity constraints on substation transformers and select distribution feeders. The Grant Avenue, State Street, and Stryker Avenue Substations will undergo upgrades to increase their capacity, allowing more electricity to pass through them and creating the necessary

infrastructure to support future load growth in Auburn, Brutus, Elbridge, Fleming, Montezuma, Niles, Owasco, Scipio, Sennett, Skaneateles, and Throop.

The New Centerport Substation Project aims to resolve urgent capacity constraints and reliability issues at the Port Byron and Weedsport Stations, which supply power to parts of Brutus, Conquest, Mentz, Montezuma, Throop, and Tyre. This project involves constructing the new Centerport Substation and transferring load from the Port Bryon and Weedsport Stations to this new substation. The work is expected to improve reliability, allow the addition of new distribution circuits, and increase capacity to support future growth.

The Auburn South Loop Comprehensive Area Study outlines necessary upgrades based on projections of grid growth over the next five, 10, and 20 years. Our analysis identified several upgrades to resolve current and future system constraints within the electric network, which covers Scipio, Genoa, and Aurora Stations, as well as three distribution tap circuits in Cayuga County.

The main goal of these projects is to tackle emerging capacity limitations in the designated area. They will increase capacity at all substations, supporting substantial residential and commercial growth and ensure backup sources are available. Besides addressing capacity issues, the projects will also improve reliability in the region.

Agriculture and farming are core to the Auburn communities, and our investments in the grid will enable a growing agricultural market in the Auburn area, with key farming operations including Willet Dairy and Ridgecrest Dairy, and other area farms who have expansion plans in the near future.

The Noyes Island Substation is a key junction point in Binghamton’s sub-transmission network and needs a complete rebuild to serve the greater Binghamton region better. The rebuild and enhancement of the Noyes Island station will provide increased reliability to the customer base.

The project will improve reliability and allow for up to 20 MW of future load growth in the area served by South Owego, enabling Crown Cork & Seal and Lockheed Martin’s continued growth in the region.

The NYSEG Binghamton Division Distribution Load Relief Program was created to detect thermal overloads in substation transformers and distribution feeders, and to suggest cost-effective solutions to address these issues. The primary objective of the project is to meet current capacity requirements. Additionally, it aims to replace aging equipment, thereby enhancing system reliability and reducing the risk of outages due to equipment failures.

The purpose of the CAS projects is to plan for upgrades that will be needed in the region based on five-, 10-, and 20-year load growth forecasts. The NYSEG Binghamton/Chenango Bridge CAS identified several system upgrades that are necessary to address current and forecasted system constraints within the region, which includes three substations: Chenango Bridge, Morningside Heights, and Nowlan Road, all located within Broome County.

The primary driver for this suite of projects is to address emergent capacity constraints within the identified area. The project will result in additional capacity at all substations, supporting residential and commercial growth while also providing a network of backup sources. In addition to resolving these capacity constraints, the project will also address reliability and infrastructure condition needs within the same area. These improvements are critical to the success and growth of key Broome County services, including Broome Community College, the Broome County Correctional Facility, and the Broome County Emergency Operations Center.

The main goal is to address emerging capacity constraints.

The project will increase capacity at all substations, supporting substantial growth in residential and commercial loads while establishing backup sources. It also boosts reliability and addresses infrastructure condition needs.

The Meyer Substation powers Conesus, Dansville, Groveland, North Dansville, Ossian, Sparta, Springwater, Wayland, West Sparta and is in need of a modernization that upgrades all circuits to 12.5 kV. This will allow our operators to maintain correct voltage levels and thermal conditions, while also enhancing infrastructure condition and reliability.

This substation in Dansville, built in 1948 on Frontage Road, serves 6,740 customers. Work has already begun, but completing the project will require additional investment, which is what we’ve requested in this rate plan. It supports NYSEG’s transmission lines and supplies energy to smaller substations across the service area. In the more than 75 years since this substation began operations, the region has grown, straining its ability to reliably serve customers.

The CAS plan for upgrades in the region using five-, 10-, and 20-year load growth forecasts. The study identified upgrades to address current and forecasted system constraints in four substations: Arkport, Canaseraga, Moraine Rd, and Webbs Crossing in Allegany and Steuben Counties.
