Company Background

New York Transco’s mission is to plan, develop, construct, and own major high voltage electric transmission projects. These projects will improve the long term viability of New York’s transmission infrastructure, reduce congestion, and advance the states’ public policy objectives which include expanding renewable power and promoting economic development.

In June 2016, New York Transco energized three new projects: Ramapo to Rock Tavern; Frasers-Coopers Corner; and Staten Island Unbottling.  These transmission upgrades not only contribute to reliability if Indian Point Nuclear Power Plant were to shut-down, they also significantly reduce upstate to downstate transmission congestion which saves money for electricity consumers.

New York Transco, together with Grid NY LLC , a subsidiary of National Grid, has proposed additional projects in the New York ISO Public Policy Planning Process to further decrease upstate to downstate transmission congestion which will save money for consumers and encourage upstate renewable development.

New York Transco is owned by Con Edison Transmission, LLC, Grid NY LLC, AVANGRID New York Transco LLC, and Central Hudson Electric Transmission.

Project Name: Ramapo – Rock Tavern 345 kV Line

Transmission Project Description:
A second 345 kV transmission line was installed on existing double circuit towers between a new 345/138kV Substation at Sugarloaf and Central Hudson’s existing, but now expanded, Rock Tavern 345 kV substation in northern Orange County. The project also allows an existing 15 mile feeder between Ramapo and Sugarloaf stations that had been operating at 138V to operate at 345 kV, adding a total of 27 miles of new 345 kV transmission between Con Edison’s Ramapo and the Rock Tavern substations.

Project Cost: (in nominal/current dollars)
Approximately $ 73 million.

Status:
The Ramapo – Rock Tavern 345 kV project was approved by New York’s Public Service Commission in 2013 and the new 345kV line was put in service on schedule in May 2016. Final relay upgrades will be complete in fall 2016.

Transmission Investment Partners, Including Public Partnerships:
The project is part of the NY Transco project portfolio. The project was developed by Consolidated Edison Company of New York and ownership was transferred to NY Transco in May 2016.

The Overall Benefits of the Project:
The Ramapo – Rock Tavern 345 kV line increases transmission capability into Southeastern New York providing additional consumer access to efficient, cost-effective generation. The line was submitted as part of a response to the New York Public Service Commission to address its Indian Point contingency proceeding.  Specifically, it is one of three state-approved transmission projects to address a potential reliability need if the Indian Point nuclear plant were to be required to shut down.  It also provides statewide benefits without such a shutdown, including developing a more robust electric grid.

Project Name: Fraser – Coopers Corners 345kV Line with Reactive Support

Transmission Project Description:
21miles of  a 345 kV transmission line was re-conductored and a 240 MVAR series capacitor bank was added between NYSEG’s 345kV Fraser substation near Delhi, New York and Coopers Corners substation near Monticello, New York.  The project also included the replacement of 12 towers and refurbishment of 20 existing towers.

Project Cost: (in nominal/current dollars)
Approximately $ 70 million.

Status:
New facilities were placed in service as scheduled on June 1, 2016.

Transmission Investment Partners, Including Public Partnerships:
The project is part of the NY Transco project portfolio. The project was developed by NYSEG and ownership was transferred to NY Transco in May 2016.

The Overall Benefits of the Project:
The Fraser to Coopers Corners 345kV Line with Reactive Support increases transmission capability into Southeastern New York providing additional consumer access to efficient, cost-effective generation.

Project Name: Staten Island Unbottling

Transmission Project Description:
The Staten Island Unbottling (SIU) project split an existing 345 kV, 2.3 mile transmission feeder between Goethals substation in Staten Island, NY and Linden Cogeneration substation in Linden, NJ into two completely separate feeders. This consisted of relocating feeder terminal connections at both Goethals and Linden substations and associated relay modifications.

Project Cost: (in nominal/current dollars)
Approximately $ 47 million.

Status:
The project was approved by the New York Public Service Commission in 2013, and the independent feeders were put into service on schedule in April and May of 2016.  Final relay upgrades will be complete in fall of 2016.

Transmission Investment Partners, Including Public Partnerships:
The project is part of NY Transco project portfolio. The project was  developed by Consolidated Edison Company of New York and transferred to NY Transco in May 2016.

The Overall Benefits of the Project:
The SIU project increases the reliability at Goethals substation by reducing the impact of losing the single existing feeder between Goethals and Linden Cogen substations.  Due to the feeder separation, up to 480 MW may be supplied from the New Jersey generating station to Staten Island in a post-contingency configuration.
The Staten Island Unbottling project was submitted as part of a response to the New York Public Service Commission to address its Indian Point contingency proceeding. Specifically, it is one of three state-approved transmission projects to address a potential reliability need if the Indian Point nuclear plant were to be required to shut down. It also provides statewide benefits without such a shutdown, including developing a more robust electric grid.
