Transmission and Interconnection

Transmission and interconnection strategies have significant impacts on offshore wind cost, feasibility, scalability, sizing, and exposure to risk. In the Offshore Wind Policy Options Paper [PDF], NYSERDA explored two of these strategies—direct radial and backbone. Direct radial transmission facilities are developed, sized, and constructed to support one offshore wind facility. Backbone transmission facilities are expandable. They can accommodate an initial facility and facilities built later on.

NYSERDA recommended a direct radial transmission approach dedicated to specific projects and owned by the developer for the first phase of offshore wind energy development in New York State. The New York State Public Service Commission supported this recommendation when adopting the Offshore Wind StandardLink opens in new window - close new window to return to this page.

To explore transmission systems for future phases of offshore wind energy development, NYSERDA and the Department of Public Service convened a technical conferenceLink opens in new window - close new window to return to this page. on September 25, 2018. The technical conference covered topics including the optimal configurations for cost-effective transmission of large-scale offshore wind development and the various options for ownership and planning processes.

Additionally, the Public Service Commision is reviewing submissions from the New York Independent System Operator's (NYISO) request for transmission needs driven by Public Policy Requirements  for 2018 to 2019Link opens in new window - close new window to return to this page. [PDF].
