About the Project

Project Mission Statement:

PSEG Long Island is committed to delivering best-in-class system reliability by expanding electrical capacity to meet the needs of the communities it serves, today and in the future. This is especially true on the eastern end of Long Island, where demand continues to grow, and upgrades to the transmission infrastructure are needed.


Project Overview 

PSEG Long Island will be continuing construction of the "Wildwood to Riverhead Conversion Project,” which will provide needed upgrades to existing substation equipment at both the Wildwood Substation in East Shoreham and the Riverhead Substation in Riverside. In addition, a new 138kV underground transmission line section will be constructed from the Wildwood Substation to just east of LILCO Road, and three existing transmission poles will be removed and replaced with three new riser poles. At the Riverhead Substation, one pole will be removed, and insulators will be replaced. 

Crews will use bucket trucks and heavy equipment to remove and replace the transmission poles, as well as trench and install the underground transmission line section.

The upgrades will ensure that you and your neighbors receive safe, reliable electric power for years to come.

Project Facts

  • New substation equipment at the Wildwood and Riverhead Substations.
  • 900 feet of new underground transmission cable from Wildwood Substation to just east of the LILCO Road in East Shoreham.
  • Three poles replaced with three new riser structures at Wildwood Substation.
  • One pole removed, one pole with new insulators at Riverhead Substation.

New York State Public Service Commission Process

Construction Process

Insulator and Pole Replacement

The existing insulators will be replaced with newer insulators on one pole near the Riverhead Substation.  Overhead bucket trucks will complete this work within the corridor.

Substation Equipment and Trenching

New equipment will be added to both the Wildwood Substation in East Shoreham and the Riverhead Substation in Riverside to accommodate the new 138kV voltage. 900 feet of new underground cable will be added to the circuit for reliability purposes.
