On October 1, 2013, National Grid filed a project with the New York Public Service Commission (PSC) that would relieve electric transmission congestion on New York's electric grid. In January 2015, National Grid proposed six innovative transmission line alternatives, collectively known as the New York Energy Solution (NYES), in response to a PSC February 2014 solicitation for alternative projects. The project alternatives were conceived and developed taking into consideration the extensive public input and community involvement, and all of these alternatives substantially improve upon the October 2013 submittal.
In September 2015, the New York State Department of Public Service (DPS) Trial Staff submitted a Final Report and Motion, outlining recommendations for two projects that would be bid on by developers, including National Grid, under the New York Independent System Operator's (NYISO) Public Policy Transmission Planning Process. The two projects include:
Segment A: A new 345kV transmission line running from the Town of Marcy in Oneida County to the Town of New Scotland in Albany County.
Segment B: A new 345kV transmission line running from the Town of Schodack in Rensselaer County to the Town of Pleasant Valley in Dutchess County, with ancillary work on a transmission line and substation in Orange County.
The September 2015 DPS recommendations were adopted by the PSC in December 2015. You can read the PSC press release regarding this decision here, and the PSC Order Finding Transmission Needs Driven by Public Policy Requirements here.
National Grid's New York Energy Solution is now comprised of two segments: Edic to New Scotland (Segment A) and Knickerbocker to Pleasant Valley (Segment B). The proposed project requires no additional right-of-way, optimizing use of the existing corridor. Additionally, the project would either visually enhance the current viewscape for New York communities, or keep it at status quo. The proposed project would relieve long-standing transmission constraints, improve grid reliability, facilitate the integration of renewable energy generators, support economic growth in the State, and address other State public policy needs.
