3 rd New Scotland - Leeds 345kV Line Actionable Project Project Description: Build one new 26 mile 345 kV circuit between National Grid’s New Scotland and Leeds substations. The project will traverse Albany and Greene Counties. It will be a single circuit transmission line using bundled 1590 ACSR conductor (2x1590 ACSR). The line will utilize or be adjacent to the existing transmission line corridor to the maximum extent possible. New Scotland is located in NYISO Zone F and Leeds is located in NYISO Zone G. Project Size: Length: 26 miles Voltage: 345kV Anticipated rating (summer normal MVA @ 345kV): 1986 Terminal Stations and required upgrades: 1. Replace New Scotland substation with a 3/2 breaker scheme. 2. Add one line position at the Leeds Station. 34
Oakdale - Fraser 345 kV Line Upgrade Actionable Project Project Description: Construct a new 345 kV line from Oakdale Substation to Fraser Substation by converting the existing Oakdale-Kattelville-Jennison 115 kV line to 345 kV operation and extending the line from Jennison on to Fraser Substation. The conductor should be sized to no less than 1431 ACSR or equivalent (1505 A summer normal). The new line will extend from the Town of Union (Broome County) to the Town of Delhi (Delaware County). Oakdale Substation is located in NYISO Zone C and Fraser Substation is located in NYISO Zone E. Project Size: Length: 57 miles Voltage: 345kV Anticipated rating (summer normal): 1505 Terminal Stations and required upgrades: New 345 kV terminals and breakers will be required at Oakdale and Fraser Substations to accommodate the new line. 35
