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.
New York State Public Service Commission Process
The New York State Public Service Commission (PSC), through the Article VII process, granted a Certificate of Environmental Compatibility and Public Need (CECPN) on July 12, 2012, and an Environmental Management and Construction Plan (EM&CP) approval on July 3, 2014, permitting PSEG Long Island to construct the project.
For information about the Article VII Application and related documents in this case, please access the PSC's website (documents.dps.ny.gov/public/MatterManagement/CaseMaster.aspx?MatterCaseNo=11-T-0116&submit=Search).

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.
