New York Transmission Company - Energy Highway

3 rd Leeds - Pleasant Valley 345kV Line
Immediately Actionable Project
Project Description:
Build one new 40 mile 345kV line between National Grid’s Leeds and Con Ed’s Pleasant Valley station.
The transmission line will traverse Greene, Columbia, and Dutchess Counties. It will utilize the existing
right of way corridor requiring a slight increase in width. It will be single circuit construction utilizing
bundled 1590 ACSR (2 x 1590 ACSR). Both terminals of the project are located in NYISO Zone G.
Project Size:
Length: 40 miles
Voltage: 345 kV
Anticipated Rating: 1986 MVA (summer normal)
Terminal Stations and required upgrades:
1. Add one line position at the Leeds Station.
2. Add one new line position at Pleasant Valley
3. Re-conductor the Feura Bush-N. Catskill #2 line using 795ACSR. This existing 115kV line traverses
Albany and Greene counties for 24 miles. This will increase the line rating by 116MVA/220MVA
(summer/winter @ 115kV).
