Con Edison, New York Transco, O&R seek approval for partial transfers of segment of 345-kV line, substation

Consolidated Edison Company of New York (Con Edison), New York Transco (Transco) and Orange and Rockland Utilities (O&R) on Jan. 26 requested New York State Public Service Commission (PSC) approval for partial transfers of a certificate of environmental compatibility and public need and the associated environmental management and construction plan (EM&CP) from Con Edison to Transco and O&R.

The petitioners said they are requesting, among other things, authorization to effectuate two transfers. First, petitioners are requesting authorization to transfer from Consolidated Edison’s (NYSE:ED) Con Edison to Transco the Sugarloaf to Rock Tavern segment of the second Ramapo to Rock Tavern 345-kV transmission line. That segment, the petitioners added, is described as a 345-kV line that connects the Rock Tavern substation to Line 28 in the vicinity of the Sugarloaf substation.

Second, the petitioners said they are requesting authorization to transfer from Con Edison to O&R the new 345-kV Sugarloaf substation. The petition seeks authorization to transfer the portions of the Con Edison certificate and associated EM&CP with respect to those two asset transfers.

The PSC in 1972 issued the Con Edison certificate for the construction of a double circuit 345-kV transmission line from the Ramapo substation to the Rock Tavern substation.

The first circuit of the Ramapo to Rock Tavern transmission line, Feeder 77, was completed in 1974. The second circuit was to be built at a later date when the need for it arose, and the PSC directed Con Edison to build towers that could accommodate both approved circuits in order to minimize future environmental impacts when building the second circuit.

The petitioners added that the PSC in 2011 approved a partial transfer of the Con Edison certificate to O&R covering the Ramapo to Sugarloaf segment of the second 345-kV circuit of the Ramapo to Rock Tavern transmission line.

The PSC in 2014 approved Con Edison’s request to complete the balance of the second 345-kV circuit of the Ramapo to Rock Tavern transmission line covered by the Con Edison certificate (the RRT project) by its approval of the EM&CP for that project, the petitioners said.

That involved, among other things, construction of the second circuit from Line 28 in the vicinity of the 138-kV Sugarloaf substation to the Rock Tavern substation, as well as construction of a 345-kV/138-kV step-down transformer and associated 345-kV switching equipment and ancillary facilities in the vicinity of the existing 138-kV Sugarloaf substation.

The RRT project is currently under construction and is expected to be in service by next June. Upon completion of that project, the entire second circuit from the Ramapo substation to the Rock Tavern substation will be operated at 345-kV and will be known as Feeder 76, the petitioners added.

The petitioners requested that the PSC approve the transfer to Transco of the portion of the Con Edison certificate, and associated EM&CP, covering the segment of the second Ramapo to Rock Tavern 345-kV transmission line beginning at Line 28 in the Town of Chester in Orange County, N.Y., then occupying the east side of Con Edison’s existing double-circuit towers located within Con Edison’s Southern Tier Interconnect right of way (ROW), for a distance of 11.8 miles, and terminating at the Rock Tavern substation located in the Town of New Windsor, Orange County.

The petitioners also asked the PSC to approve the transfer to O&R the portion of the Con Edison certificate, and associated EM&CP, covering the new 345-kV Sugarloaf substation located on the south side of Sugarloaf Mountain Road in the Town of Chester, Orange County.

The petitioners noted that Transco will initially enter into an agreement with O&R for the day-to-day operation and maintenance of Transco’s segment of Feeder 76. O&R maintains, under contract with Con Edison, the 345-kV overhead transmission facilities owned by Con Edison within the O&R service territory, including Feeder 77.

Con Edison is a wholly owned subsidiary of Consolidated Edison (NYSE:ED). Transco is jointly owned by these affiliates of the New York transmission owners: Consolidated Edison Transmission, Grid NY, Iberdrola USA Networks New York Transco, and Central Hudson Electric Transmission. O&R is a wholly owned subsidiary of Consolidated Edison.
