Propel NY Energy in the Town of Oyster Bay

Propel NY Energy is a 90-mile, six-segment transmission improvement project across parts of Long Island, Queens, Bronx and Westchester County. Transmission lines carry electricity long distances, from where it is generated to the distribution lines that bring it to homes and businesses.  

A portion of four segments are proposed in Oyster Bay, consisting of approximately 31 miles of new underground transmission line through the Town, and in or adjacent to four villages, nearly 2 miles of submarine cable, and a new substation on utility-owned property. (See maps at right).

All routing is subject to permitting and further evaluation.

A project route was originally proposed in the July 2024 Article VII permitting application. In April 2025, viable alternative routes were identified in response to extensive input from local stakeholders — including municipalities, community organizations, and civic groups — and represent potential pathways to achieve the project’s objectives. These routes were further evaluated for inclusion in the Project’s permitted route. On June 25, 2025, Preferred Project Routes in Nassau County were filed to the Article VII application with the New York State Public Service Commission for continued permitting evaluation. The Preferred Route and all past routes can be viewed at right.
- A robust electric transmission network is fundamental to power our daily lives. It also supports healthier communities, and jobs and economic opportunity. 
- Electricity use is increasing and placing more demands on an aging system. 
- New York’s transmission system requires upgrades and expansion to improve reliability and create the resilient pathways needed to deliver clean energy to local communities and throughout the state.  
Pending regulatory approvals, construction is estimated to begin in 2026, with a 2030 in-service date. Construction will be done in short durations in specific areas across the full project.
