New transmission lines to transform New York's energy landscape

In a recent government meeting, officials outlined an ambitious infrastructure project aimed at enhancing the electrical transmission network across several counties in New York. The plan involves the construction of approximately 90 miles of new underground and submarine transmission lines, primarily consisting of 345 kilovolt (kV) lines, with one segment featuring a 138 kV line on Long Island.

The project will span Nassau County, Suffolk County, Queens, Bronx, and Westchester County, with a significant focus on a key segment represented by a dark blue line on the project map. This line will begin at the existing EGC substation in Uniondale, Hempstead, and will traverse through parts of North Hempstead before crossing into Queens and the Bronx, ultimately terminating at the Tremont substation.

Construction is projected to take around four years, with an operational target set for May 2030. Once completed, the new transmission lines are expected to provide substantial benefits to the region and the state, enhancing the reliability and capacity of the electrical grid. The meeting emphasized the importance of this project in meeting future energy demands and improving infrastructure resilience.
